Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Vehicle will not accelerate after a stop at a light or after taking a highway from a ramp, the engine will rev up but the vehicle will not change gears, after a pull over to the shoulder of the road shutting off the engine and restarting it will run normal. This happened for about 20-30 times until yesterday I get out of work pulled out of the parking lot noticed the vehicle was in limp mode stuck in 2nd and will not change gears. I did some research and found out that the cause was from the valve body of the transmission or the conductor plate and only the dealer is aloud to repair it ???. …”
