However, it is one of the more expensive car part replacements that you will need to make. The cost of replacing a bad transmission valve body will depend on the make and model of your vehicle. However, replacement of the entire valve body assembly is quite common. If you take your vehicle to a qualified transmission repair shop, there is a chance that the shop may be able to replace an individual component instead of the entire valve body. There are many tiny components inside a transmission valve body that must function exactly as designed for proper transmission operation. We recommend Parts Geek for the best prices and selection. This may also cause you to be stuck in neutral or a single gear. 5) Shifting Delaysĭoes it take a long time to shift gears from reverse or drive (or the other way around)? Sometimes a malfunctioning transmission valve body will delay the fluid flow, causing delays in gear shifts. ![]() Once this happens, the gears cannot be pressurized properly which degrades the performance of the vehicle. If the transmission is not able to downshift, then hydraulic fluid may not be entering or navigating the transmission valve body properly. Your shifter should never slip out of gear if your transmission valve body is fully functional. If you try to change gears with the shifter and you notice it slips regularly, then you may have a problem with the transmission valve body. If the answer is yes to any or all of these scenarios, then chances are you may have a bad transmission valve body. You may even hear them simply from changing gears. 2) Banging Noisesĭo you notice any banging noises as you apply pressure to the brake pedal and slow down? Perhaps you also hear these noises when you put the car in reverse and drive backwards. If one of these solenoids were to fail, you may find yourself locked out of certain gears, or you may be unable to shift at all.Ī qualified transmission shop may be able to replace a single component inside the valve body, or you may need a new valve body depending on what the root cause of the problem is. There are many solenoids that the TCM can turn on and off to direct the flow of transmission fluid inside the valve body. Below are some of the common symptoms you may experience if you have a bad transmission valve body.

The transmission fluid is sent to the right place at the right time by using hydraulic circuits, controlled by a system of valves and solenoids that direct the flow.ĭepending on the position of each solenoid, each hydraulic circuit activates a different function of the transmission. Not to be confused with the intake and exhaust valves in your engine, the valve body is an assembly inside an automatic or CVT transmission that routes automatic transmission fluid (ATF) throughout the transmission. How Can I Prevent This Problem From Happening?.Transmission Valve Body Replacement Cost.And if you bought it used after 2004, the inspection/jet kit install needed to be done before the car was sold to you or it was a violation of federal law.

It's cheaper for them to just fix the ones under warranty that fail.Īs to KRS62's post, as others have pointed out the warranty on the 2nd gen trannys was expanded to 7 years/100K miles by Acura, and then through a class action lawsuit that warranty got extended by an additional 9 months and 9,000 miles, so it's now 7 years, 9 months/109K miles. No sense spending a lot of money on designing a fix for a part you aren't making or using any more. By the time it was discovered they were already working on the tranny design for the 3rd gen TLs and so the 2nd gens just got a band-aid fix (reprogrammed ECU, new fuel rails, and the oil jet kit). ![]() ![]() Well you will still see the problem on anyone with a '00 - '03 TL/CL because the problem was never fixed.
