Something is wrong with the 3-4 clutch assembly, the apply piston, & or the hydraulic circuits for the 3-4 clutch.

Goes no where fast because the 3- 4 clutch is not working for some reason.

I know all about blowing out the 3-4 clutch in m 87 Vert 2 years back.

Rebuilt & blueprinted my original trans last year.

My 700R4 trans works as good as the day I reinstalled it 10,000 miles ago.
Hard & very fast driving too.

If he lost 4th gear in a 1987 Super T-10 trans with the Doug Nash Drive Overdrive,
The trans would be laying on the ground blow to pieces.

The 3-4 slider of the synchronizer assembly engages the Input shaft "DOG" teeth.

I have blown M-22 Muncies apart and oiled the black top up.
They are similar to a Borg Warner Super T-10.
