4l60e no reverse Hello,
I recently rebuilt my 4l60e and finally installed it into my 98 c5 corvette.
I did put a 3200-stall torque converter (not sure if this really matters).
Off the ground the wheels spin in all gears and will go above 30mph without touching the gas.
On the ground the car won't go in reverse, but I can get it to move back slightly.
I have no way to back if off my lift.
I was very detailed in the reassembly of the transmission. The only thing I was unsure about was setting the pump into the transmission as I needed to tap it into place.
I did check the reverse piston with air pressure during assembly, the front piston lip seal was a pain but after 3 lip seals I was able to successfully seat it but putting it in the freezer.
1 other concern I have is the spacer plate as I used a truck spacer place but ensured all the holes were the correct size (when compared to the old spacer plate).
I also did used the transgo sk 4l60e shift kit and a sonnax smart shell.
Where should I start? Is there something wrong with the tune possibly?
Update dropped pan, nothing obviously wrong with valve body.

You likely tore or omitted the rev teflon rings on the pump stator would be my guess, The only other is forgot to tighten the three bolts on the plate just under the solenoids a common mistake.
