4T65-E rebuilt.

When run on a dyno it had no reverse and went forward in neutral.

Dyno opperator knows nothing about transmissions so I couldn't get any more info

Thanks

It would help if the dyno operator remembered whether reverse was binding up or was it a neutral condition? My first suspicion would be that the forward clutch's are somehow jammed.

Oh wait i was thinking of the 4L65E yours is a 4T65E.

I would like to know if rev was a bind also but the dyno guy knows nothing about transmissions
I'm thinking 1-2 band jammed on some how or some idiot left the accumulator spacer plate out.
That would be me.

Never seen this before

I will let you know what I find.



Thanks  Bob

Overrun servo pin missed the band and jammed the band into the drun
