When your car starts lurching, stalling at stoplights, or slipping between gears, the problem is often a small but critical part inside the transmission valve body: a solenoid. These electrically controlled valves direct transmission fluid to engage the right gear at the right time. A failing solenoid can make a smooth-shifting car feel unpredictable, but replacing it is a straightforward and affordable fix that can restore normal operation without needing a full transmission rebuild.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You might drive a Chevy truck with a slipping torque converter (a device that locks the engine to the transmission for better fuel economy), or a Honda Civic stuck in first gear. Either way, this breakdown of the best automatic transmission solenoid options will help you choose the right replacement based on real-world fitment, durability, and value.
Our Picks at a Glance
How To Choose The Best Automatic Transmission Solenoid
Picking the right replacement solenoid starts with your car’s transmission model, not just the brand name. A 4L60E solenoid set won’t work in a 4F27E Mazda, and a shallow-pan part will cause leaks if your truck has a deep pan. You also need to decide whether you are fixing a single known code (like P0753 for shift solenoid A) or doing preventative maintenance while the pan is off.
Know Your Transmission Type and Part Number
Every automatic transmission uses a specific set of solenoids that differ in shape, connector style, and fluid pressure rating. Check the transmission code on your vehicle (e.g., 4L60E, 4L80E, 4F27E) and cross-reference OEM part numbers like 24230288 or 28200-PLX-003. Using Amazon’s “Confirm Fit” tool with your exact vehicle trim and year is the best way to avoid returns.
Single Solenoid vs Kit: Which Do You Need?
If a diagnostic code points to one specific solenoid — say the TCC (Torque Converter Clutch) solenoid — a single replacement like the Dorman 926-378 is the most direct fix. If you have high mileage (over 150,000 miles) and are already dropping the pan, a full kit like the SecosAutoparts 6-piece set lets you replace all shift and pressure solenoids at once, saving future labor costs. The trade-off is that a kit costs more upfront and may include solenoids that were still working.
OEM vs Aftermarket: Quality and Warranty
OEM (Original Equipment Manufacturer) parts like the GM Genuine solenoid are built to factory specifications and carry the brand’s warranty, but they come at a premium price. Aftermarket brands like Dorman and A-Premium often match OEM fit and function while costing less, and many offer their own one-year replacement guarantees. The key difference is material and testing: some aftermarket solenoids use laser welding and Viton (a heat-resistant synthetic rubber) seals for better durability, while bargain units may fail earlier. A lengthy warranty and high review count (especially 300+ ratings) are strong indicators of a tested part.

In‑Depth Reviews
1. Dorman 926-378 Transmission Torque Converter Clutch Solenoid
The Dorman that kills chugging and stalling before you even leave the driveway.
If your Chrysler, Dodge, or Ram van or truck dies when you come to a stop or shudders on the highway, the torque converter clutch solenoid is usually the culprit. This Dorman TCC solenoid — at just 2.56 ounces (a featherweight, 4.4 times lighter than the ApplianPar Civic solenoid) — is a direct replacement that matches the shape and plug of the original factory part. It runs on 12 volts, is made from steel or aluminum, and buyers report “it stopped the shuddering and stalling” after installation.
One reviewer on a Dodge van noted it was an exact match in shape and plug for the OEM part, and the van “no longer dies when I stop.” The build quality comes with a limited lifetime warranty, which is rare at this price point for a single solenoid. The only real task is finding it under the vehicle — the job is straightforward but takes some patience with access from underneath.
Why it wins
- Exact fit and plug match for many Chrysler/Dodge/Ram models
- Weighs just 2.56 oz, easy to handle in tight spaces
- Limited lifetime warranty from a brand with over 100 years in the business
Before you install
- Only for torque converter clutch function, not shift solenoids
- Access can be tight — dropping the pan may require extra time
Grab this if: your Chrysler/Dodge/Ram is stalling or shuddering at stops and you want a TCC solenoid that fits perfectly and carries a lifetime warranty.
Look elsewhere if: you need shift solenoids A/B or a pressure control solenoid — this only handles the torque converter clutch circuit.
2. GM Genuine Parts 24225825 Pressure Control Solenoid Valve
Factory-spec muscle for fixing soft shifts and slipping on takeoff.
For GM owners — especially Chevy Impala, Cobalt, and Pontiac G6 drivers — the pressure control solenoid (often called the EPC solenoid, which stands for Electronic Pressure Control) is what fine-tunes line pressure for firm, predictable shifts. When this part fails, you get long, mushy shifts that feel like the transmission is sleeping. This GM Genuine part is built to the original factory specification and weighs just 2.72 ounces, making it even lighter than the Dorman TCC solenoid above. One certified auto tech buyer reported that a bad EPC solenoid was confirmed via pressure test; after replacing it along with filter and fluid, “pressures normalized; shifts firmed up.”
The catch is the labor — one reviewer with a 2005 GTP Comp-G described it as a “very difficult job (9 hours with lift to drop cradle).” The part itself is the exact factory component, but accessing it can require removing the subframe on some GM models. If you are already replacing shift solenoids, doing the pressure control solenoid simultaneously saves a repeat teardown. Owners mention that after replacement, you should check fluid level immediately because the system may need an extra 2.5 quarts.
Real-world fix: One buyer’s Impala had long soft shifts and slipping on takeoff — this solenoid, combined with fluid and filter changes, restored normal pressure and firmed up every gear.
Best for: GM drivers who want an OE-grade pressure control solenoid and are willing to tackle a tricky install (or pay a shop) for factory-reliable shift quality.
Not your part if: you only need a shift solenoid A/B — this is strictly the pressure control valve (EPC), not a shift solenoid.
3. HERCOO 4L60E Shift Solenoid Valve A&B with Filter Gasket Kit
The kit that bundles solenoids, filter, and gasket for a complete deep-pan rebuild.
If you drive a 1998-and-up Chevy or GMC truck with a 4L60E transmission and a deep oil pan, this 4-piece kit from HERCOO gives you both shift solenoids A and B plus a filter and gasket — everything you need to refresh the valve body while the pan is off. Weighing 22 ounces, it is a substantial kit compared to the single 2.56-ounce Dorman, but that weight comes from the included hardware. One buyer with a 2002 Silverado Z71 replaced both A and B solenoids because the “B servo went out” and reported the truck “shifting great again.”
There is a critical fitment trap, though. This kit is designed for a deep pan, and one reviewer warned that it “does NOT fit 2004 GMC or anything using a SHALLOW pan.” Another buyer found the filter didn’t fit their 2007 Envoy SLT 4×4, though customer service worked out a solution. Always check your pan depth before buying — if your transmission has a shallow pan, this kit will not work. The 1-year replacement warranty gives some confidence, but fitment verification is on you.
What’s in the box
- 2 x 4L60E shift solenoids A and B (interchangeable per some buyers)
- 1 x transmission filter and 1 x pan gasket included
- 1-year replacement warranty if the item fails
Check before buying
- Only fits deep oil pans — shallow pan transmissions are incompatible
- Some buyers received a filter that did not fit their specific model
Ideal for: GM truck owners with a 4L60E deep pan who want a single order that covers solenoids, filter, and gasket for a full valve-body refresh.
skip it if: your GM vehicle has a shallow transmission pan — you will need a different filter and gasket, and these solenoids may not sit correctly.
4. A-Premium Transmission Shift Solenoid for Chevy, GMC, Cadillac
A 1.56-pound solenoid that customers note fits like a glove and fixes shifting on the first drive.
For owners of Chevy Silverado, Tahoe, Suburban, GMC Yukon, or Cadillac Escalade with a 4L60-E transmission (deep pan only), this A-Premium solenoid replaces OEM numbers 24230298 and 10478120 among others. One reviewer noted it was a “perfect fit for 2001 Chevy 1500; easy install, fixed shifting issue immediately, runs smoothly.” At 1.56 pounds, it is noticeably heavier than the 2.56-ounce Dorman TCC solenoid — a weight difference of about 1.5 pounds — reflecting the larger body and internal coils of a shift solenoid versus a TCC unit. The package dimensions are 10.59 x 8.35 x 4.8 inches, about 2.5 times larger than the SecosAutoparts kit’s box, so it comes well-protected.
The one-year unlimited-mileage guarantee is a solid safety net, though the fitment note is strict: this is for deep oil pans only, not shallow pans. Another buyer highlighted that the filter seal was “hard to install” and had to be driven in with a socket, so have a socket driver ready if the seal is tight. Overall, the 4.6 out of 5 rating from 85 reviews suggests consistent quality, but confirming your 16-bolt deep pan before ordering is essential.
From the shop floor: “Fit like a glove and no leaks” and “Came on time and fixed my issues” — two separate buyers confirming consistent fitment.
Right for you if: you have a GM truck or SUV with a 4L60-E deep pan and want a shift solenoid that buyers consistently call a direct fit with immediate results.
Wrong choice if: your transmission has a shallow pan — this part is specified for deep pan (16-bolt pan) applications only.
5. MOTOR-ZONE 2PC Shift Solenoid for Chevy 4L80E/4L85E
A no-frills 2-pack that got a Chevy Silverado shifting again while staying affordable.
If you own a heavy-duty Chevy Silverado 2500/3500, Suburban 2500, or Express van with a 4L80E or 4L85E transmission, this MOTOR-ZONE pair covers shift solenoids A and B (replacing OEM numbers 24230288 and 24230289). Each solenoid weighs just 6.4 ounces for the pair, making them lighter than the 11.3-ounce ApplianPar Civic unit. The manufacturer uses laser welding and a Viton sealing system (a heat and oil-resistant rubber) for high performance, and reviewers point out that they “works like they should and fixed my shifting problem.” However, with only 16 ratings at 4.4 stars, this is a newer product with less long-term feedback than the Dorman or A-Premium options.
The fitment list is broad — covering from 1991 to 2009 models — but the 4-speed automatic compatibility means you must verify your transmission generation. One potential gap: the product has no stated warranty beyond standard Amazon returns, unlike the A-Premium one-year guarantee. For a budget-friendly quick fix on a work truck, this is a solid entry, but for higher-mileage rebuild projects, a kit with a longer warranty might give more confidence.
What works
- Covers both shift solenoids A and B in one affordable 2-pack
- Laser welded with Viton seals for better fluid resistance
- Fits a wide range of GM heavy-duty trucks and vans from 1991-2009
What’s missing
- No stated manufacturer warranty period
- Low review volume (16 ratings) limits reliability picture
Choose this for: a budget-friendly 2-pack to fix a 4L80E/4L85E shift problem on a Chevy truck or van when you don’t need a full kit.
Pass if: you want a multi-year warranty or need pressure control solenoids — this is strictly shift A and B.
6. SecosAutoparts 6PCS 4F27E Transmission Solenoid Kit for Mazda
Six solenoids for Mazda owners who want to flush every bad code at once.
If you drive a Mazda 2, 3, 5, 6, CX-7, or MPV with the 4F27E (4-speed) transmission, this kit covers shift solenoids A and B, PWM (Pulse-Width Modulation — solenoids that vary fluid pressure smoothly) solenoids C, D, E, and an EPC solenoid — all six in one box. At 1.96 pounds, it is 26% heavier than the single A-Premium solenoid (1.56 pounds), but that weight makes sense because you are getting six separate valves. One buyer with a 2009 Mazda 3 at 180,000 miles reported: “At 180k miles, fluid black with filings. Needed 3 drain/fills and full solenoid replacement to clear codes and restore TCM/ECU signals.” That tells you the kit is a thorough solution for high-mileage transmissions that struggle with multiple codes at once.
The box is compact at 4.21 x 3.74 x 2.91 inches — about 2.5 times smaller than the A-Premium unit’s packaging — so it stores easily. However, incoming quality control is a real concern. One buyer received a “destroyed” box with solenoid bags hanging out, and two of the first set of solenoids were faulty, leading to a return. The manufacturer states they test each solenoid on a machine, and oil stains are normal (a small residue from testing), but the inconsistent packing suggests buying from a seller who handles returns smoothly. This kit is exclusively for Mazda 4F27E transmissions — it does NOT fit Ford models, despite shared platforms.
The upside
- Replaces all six solenoids in a 4F27E transmission with one order
- Tested at the factory before shipping (oil residue is normal)
- Compact packaging — 4.21 x 3.74 x 2.91 inches
The downside
- Multiple reviews report receiving used or faulty solenoids in damaged boxes
- Strictly for Mazda 4F27E — does not fit Ford transmissions
Intended for: Mazda owners with a high-mileage 4F27E transmission who want to replace every solenoid at once and are comfortable checking each unit before installation.
Avoid if: you want a single solenoid for a specific code (P0761, P0753) — this kit includes solenoids you may not need, and QC has been inconsistent.
7. ApplianPar Automatic Transmission Shift Solenoid for Honda Civic 2001-2005
The lightweight fix that got a 2002 Civic out of first gear and back on the road.
For Honda Civic owners (2001 to 2005 models) facing error code P0753 — a bad shift solenoid A that locks the transmission in first gear or reverse — this ApplianPar replacement is the budget-friendly answer. Weighing 11.3 ounces, it is about 4.4 times heavier than the Dorman TCC solenoid and significantly lighter than the OEM part, according to one buyer: “02 Honda civic, a bit lighter than the OEM but it works great.” The reviewer had lost first and second gear before replacing this solenoid; after the swap, the Civic shifted perfectly again. Another buyer with a 2002 Civic had the same P0753 code and reported the car “couldn’t shift out of first/reverse” until this solenoid fixed it instantly.
The part is a straight replacement for OEM number 28200-PLX-003, and the 4.8 x 3.27 x 2.24-inch package is small enough to fit in a glove box. However, the reviews are polarized: one buyer called it “garbage product. Did not work,” while five others confirmed it solved their issue. With a 4.1 out of 5 rating across 112 reviews, the majority of buyers had success, but the polarized feedback means you should be ready to return it if your specific transmission has additional problems beyond a simple solenoid failure.
Why it works for most
- Direct replacement for Honda Civic 2001-2005 shift solenoid A (P0753)
- Lightweight at 11.3 oz — easier to handle than the heavier OEM unit
- Over 100 reviews with 4.1-star average, majority report fixed shifting
The risk
- Polarized reviews — “worked great” vs “garbage” with no middle ground
- Slightly lighter construction may feel less durable than factory OEM
Top pick for: Honda Civic owners with a confirmed P0753 code who want the lowest-cost shift solenoid replacement and are willing to test fitment before permanent installation.
Not for you if: you have a different transmission code or need a solenoid for a non-Civic Honda — this part is specific to Civic 2001-2005 only.
Understanding the Specs
TCC vs Shift vs Pressure Control Solenoid
Not all solenoids do the same job. A torque converter clutch (TCC) solenoid controls when the torque converter locks up — when it fails, the car may shudder or stall at stops. Shift solenoids A and B manage gear changes (1-2 and 2-3 shifts); when they go bad, you get stuck in one gear or get harsh shifts. A pressure control (EPC) solenoid adjusts the line pressure that firms up each shift — a faulty EPC causes long, mushy shifts that feel like the transmission is slipping. Make sure you match the solenoid type to the diagnostic trouble code (DTC) your car is throwing.
Voltage and Electrical Match
Every automatic transmission solenoid in this guide runs on a 12-volt electrical system, which is standard for most passenger vehicles. The critical electrical spec is the resistance (measured in ohms) of the solenoid coil — typically 20-30 ohms for shift solenoids. If you install a solenoid with the wrong resistance, the transmission control module (TCM — the car’s computer that manages shifting) may not be able to drive it correctly, causing codes or no function. Always compare the new solenoid’s resistance to the factory spec for your transmission using a multimeter if you want to be sure.
Deep Pan vs Shallow Pan Fitment
GM 4L60E and 4L65E transmissions come in two distinct oil pan depths: deep pans (16-bolt pattern, holds more fluid) and shallow pans (fewer bolts, sits flatter). The A-Premium and HERCOO solenoids are explicitly designed for deep pans only. Installing a deep-pan solenoid in a shallow-pan transmission will result in a poor seal and leaks because the solenoid sits at a different height. Before ordering, count the bolts on your transmission pan or check your vehicle’s service manual to confirm the pan type.
Material and Seal Quality
Transmission solenoids live inside hot, pressurized fluid, so material matters. Cheaper solenoids use basic plastic and rubber seals that can degrade over time. Better aftermarket units — like the MOTOR-ZONE and Dorman — use Viton seals, which are more resistant to heat and transmission fluid breakdown, and laser-welded joints to prevent leaks. Stainless steel exteriors (as seen in the HERCOO kit) resist corrosion better than painted steel. If you drive in severe conditions (towing, extreme heat, stop-and-go traffic), spending a little more on a solenoid with Viton seals and a metal body is worth it for longer service life.
