Transmission Solenoid Replacement Cost

Your automatic shifts hard, slips, or gets stuck in one gear, and the check engine light is on. The shop reads the codes and says a transmission solenoid has failed. Before you pay, it helps to know what the part and the hours really cost.

So how much does a transmission solenoid replacement cost? About $270 to $775 at a shop for one solenoid or a solenoid module, worked out from the part prices and the carmakers’ own job times. The part alone is about $112 to $431.

In this guide I will show you why a solenoid code usually does not mean a new transmission, what shops charge, how long the job takes, and what owners were quoted.

A Solenoid Code Rarely Means a New Transmission

Solenoids are small electric valves that an automatic transmission uses to shift gears. They are normally mounted on the valve body, which a shop reaches by dropping the transmission’s oil pan.

The carmakers say the same in their own bulletins. Kia’s bulletin for its 6-speed automatics tells dealers to replace the solenoids when the codes show up, and not the transmission, with the transmission left in the car.

Hyundai’s bulletin for the 2018 Sonata 2.0T says not to replace the transmission for its solenoid codes, but the related part. On some transmissions the solenoids come as one solenoid pack or module, which you replace as a whole.

Street Smart Transmission, a transmission shop in Tampa, Florida, explains that a failed solenoid can put the car in limp mode. The transmission then stays in 2nd or 3rd gear, and you should only drive it home or to a shop.

What Shops Charged

The Tampa shop published these sample prices for four cars in 2019, with the dealer price next to its own:

The shop also notes that the fluid drained from the pan is normally put back in. New fluid adds about $20 to $50, at $6 to $10 a quart for 3 to 5 quarts.

How Long the Job Takes

The carmakers publish the hours they pay their dealers for warranty work, and those bulletins sit on the NHTSA website:

• Kia gives 1.2 to 2.8 hours to replace the solenoids on its 6-speed automatics, depending on the model.
• Ram gives 2.6 hours to replace the solenoid pack on the 2016 and 2017 ProMaster van.
• GM gives 2.6 hours to replace the solenoid and control module unit with the valve body on the 2025 and 2026 Chevrolet Trax and Buick Envista.

Tekmetric, a company that makes software for repair shops, found the average US labor rate was $132 an hour in June 2026. So 1.2 hours is $158.40, 2.6 hours is $343.20 and 2.8 hours is $369.60.

What the Parts Cost

Here are part prices I checked on October 7, 2026, from ToyotaPartsDeal, a Toyota dealer’s parts website, RockAuto, a parts website, and the Mopar eStore, where Chrysler dealers sell Mopar parts:

Now put the parts and the hours together. The cheapest Toyota solenoid and 1.2 hours is $112.09 + $158.40 = $270.49.

The most expensive Toyota solenoid and 2.8 hours is $335.23 + $369.60 = $704.83. The Mopar module at Mopar’s own price and Ram’s 2.6 hours is $431.25 + $343.20 = $774.45, or $264.89 + $343.20 = $608.09 bought at RockAuto.

What Owners Were Quoted

Here is what owners were quoted, with links to their posts:

• A transmission shop quoted $1,500 to replace the solenoid pack on a 2012 Ram 1500 with 112,000 miles, in September 2020. A mechanic who answered on 2CarPros put the part at about $500 and the labor at 1.5 to 2 hours.
• A Toyota dealer told a Tacoma owner that two solenoids, SL-T and SL-2, would cost about $1,300, in May 2010.

Both quotes are far above the worked-out prices above. So ask for the part price and the hours on paper, and get a second quote from an independent shop.

Check for a Free Fix First

If you own a 2016 or 2017 Ram ProMaster with the 6-speed automatic, ask a Ram dealer about Customer Satisfaction Notification V46.

Ram found that the solenoid coil terminals on these vans were built out of specification, which can cause an on-and-off electrical connection. The notice from November 2019 has the dealer replace the solenoid pack at no charge.
