New Transmission Issues - Grinding/Notching 6th Gear occasionally
I recently replaced my transmission with a T-56 Level V from RPM Transmissions. At the same time, new GM trans mounts, LS7 clutch and flywheel were installed. I had a local installer do the work.
After the replacement, the 2nd to 3rd shift would occasionally grind, and shifting into 6th (from 4th or 5th) would either grind or notch into 6th. This happens once every 5 to 10 shifts. If I hold the shifter tightly into place in 6th, this seems to help. With the old shifter/trans/etc, I could put the car into gear, and I didn't have any issues.
Since the transmission replacement, I have also replaced the motor mounts (RevShift Blue), installed a PISNUOFF short throw shifter with Creative Steel bushings, and then took the car to RPM for them to take a look at things.
When RPM took the car for a drive, they did have issues shifting into 6th. They removed the trans and replaced everything associated with 3rd & 6th gear. I'd really like to thank they guys at RPM, they have been great to work with throughout the entire process. RPM mentioned that even with my new shifter, it still seemed to have a lot of play. I'd guest there is 1" to 1.5" of side to side play when in any gear.
I still get grinds or notches when shifting into 6th gear. 2nd to 3rd shifts seem better so far.
