A couple weeks ago, I got my T56 rebuilt, with 3rd and 4th faceplated. Today was the first time on the dragstrip. In all 4 of my passes, the 2-3 WOT powershift was amazing: fast and effortless, I still can't believe it.
But my 3/4 powershift resulted in a horrible grind in all 4 passes. I managed to get it into 4th on 2 passes. In the other 2, I didn't want to force it in, so I let off and coasted to the traps.
On the drive home from the dragstrip, transmission was whining for the first time...don't know if that means anything. Normal shifting is fine, however.
I thought that maybe the problem was due to a hot sticking clutch, so tonight I went out on the highway with a nice cooled off car. Did a 3rd gear pull...and went I tried to powershift @ 6500 rpms, it went in with a terrible grind.
Something is wrong.
I tried searching for this problem, grinding/lockout while powershifting a faceplated transmission. It seems to be non-existent.
Don't know where to begin looking, any ideas?
