It controls fluid flow for smooth gear shifts and works with solenoids , sensors, and hydraulic circuits to automate shifting. Type of valve body : Your vehicle may have an electronic or hydraulic valve body, which can impact the price. Use jack stands to safely raise the car for access to the transmission.
For example, a hydraulic piston pump is more expensive than a gear pump but more efficient and long-lasting. Illuminated CheckEngineLight (CEL): If your CheckEngineLight or a dedicated transmission warning light is on and you’re having transmission troubles, it may be due to the pump.
This engages the torque converter, which uses this hydraulic pressure to shift to the correct gear. Transmission control solenoid: Regulates the pressurized hydraulic fluid (line pressure). This limits your engine RPMs and driving gear (on automatic transmission vehicles) to prevent damage to other car parts.
NOTE: Replacing multiple camshafts at once can save you labor costs as the engine is already disassembled. Type of camshaft: Modern cars usually use solid roller or hydraulic roller camshafts. Solid rollers typically cost more than hydraulic rollers as they’re built for high-performance engines and higher RPMs.
Here are some common signs that could mean its time for a replacement: Checkenginelight activating: If your checkenginelight comes on, it could mean theres an issue with the VVT system, but further diagnostics are needed since this light can indicate various problems.
Contaminated or Low Transmission Fluid Just as motor oil keeps your engine running smoothly, transmission fluid is essential for both automatic and manual transmission systems to function properly. The transmission fluid lubricates and maintains hydraulic pressure for smooth gear shifts. What’s worse? But that’s not all.
This results in engine overheating and can cause the temperature gauge to spike into the red zone, triggering the CheckEngineLight. You’ll Be Unable to Steer Easily A bad drive belt can cause the power steering pump to fail, preventing it from circulating hydraulic fluid.
If you suspect that transmission lines are damaged, immediately contact a car repair shop for a diagnosis and proper fix. How to Diagnose and Fix a Faulty Transmission Line Always rely on a certified technician from a trusted car repair shop to fix any damage to the transmission system and ensure precise fluid flow.
In automatic systems, this fluid creates hydraulic pressure to shift gears smoothly. That’s why you should always let an autorepair mechanic perform the transmission fluid exchange. Switch off the engine and park the vehicle. Is It Worth Replacing the Transmission Fluid ? Not at all!
