2004-2007 Cadillac CTS-V General Discussion Discussion, Transmission grind under hard accel in Cadillac CTS-V Series Forum - 2004 - 2007; My trans grinds when shifting Into 3rd only at high rpms or hard accel but when normal driving it shifts ...
My trans grinds when shifting Into 3rd only at high rpms or hard accel but when normal driving it shifts fine no grinds. I also noticed one time I had a hard time shifting into reverse gear would just not go In, is my trans messing up already the car is at 60k
That was the first thing I did cuz I noticed my pedal would stick to ground on hard accel so I bled it but it still does it but pedal don't go all the way down anymore but I did notice my pedal got a lil stiffer with the bleedin which felt way better... I also noticed that sometimes my gears grab nice n somtimes they feel sloppy when shifting like the shifter feels loose
If the clutch hydraulics are not an issue, the GM trouble shooting procedure calls for two tests. One is to establish whether the transmission can be shifted from neutral to any other gear with the motor not running (static test). The second is establish whether the transmission can be shifted from neutral to any other gear with the motor running (dynamic test). If it fails the static test the issue is likely with the shifter, or transmission mounting. If it fails the dynamic test, the issue is likely inside the transmission.
Having said all that, the pedal sticking to the floor symptom can indicate a failing clutch pressure plate.
