All automatic transmissions have a valve body that serves as the main control center. The valve body contains multiple passages and channels that direct hydraulic fluid flow to different valves to engage the required clutch and shift to the desired gear. The valves comprising the body serve different purposes, and their names reflect their functions. For example, if the body has 2-3 shift valves, it’s responsible for shifting from second to third gear. And the 3-2 valve is responsible for shifting from third to second gear.
So, the block consists of a body with a cover that closes and protects the valves from the external environment. The block can have one to three valves installed – depending on the vehicle’s configuration. Sometimes, you can see that an oxidation line has appeared on the cover bend, the seal has deteriorated, and water is entering the block. Consequently, everything becomes corroded inside. Additionally, when water penetrates, it’s not just the valves that suffer.
The block operates as follows: first, compressed air is supplied. When the electromagnetic valve is not activated, it receives a PWM signal at 1% of system voltage; when activated, it receives a signal at 98% of system voltage. And when the control unit receives confirmation that gear shifting has occurred, the valve becomes inactive and again receives a signal at 1% voltage.
If you suspect your automatic transmission valve body is faulty, look for certain signs. The most noticeable ones are noises during gear shifting. If you hear loud sounds during deceleration, gear shifting, or reverse driving, this indicates a valve body malfunction. Another sign is lever slippage when attempting to shift gears. When the body works properly, the handle doesn’t slide so easily. You might also notice slower movement in reverse or during gear shifts. All these indicate that something is wrong with your automatic transmission’s valve body.
Initially, these problems might be easy to miss. But if you drive your car more than 30 minutes a day, the problems will become more apparent as your transmission heats up. If you encounter any of the above problems, immediately take your vehicle to the nearest repair center and have your valve body checked for replacement.
Today professional repair shops typically opt for complete replacement as a preferable alternative to repair. To determine the best option for you, you should compare the costs of both approaches. When it comes to parts alone, an aftermarket transmission valve body replacement can range from approximately $100 to $2,500. Labor costs for professional valve body replacement typically add another $300 to $1,000 to the total bill. However, these figures are estimates and may vary considerably. It’s advisable to get quotes from several reputable shops in your area to determine the most cost-effective solution. What is really important, is to choose a reliable mechanic service, so we recommend to work with licensed representatives only.
