I have a 2000 Ford Ranger in which the transmission slips from 1st to 2nd. Also there is a bit of hesitation when I put it into reverse. We dropped the valve body and found that the circular part of the plate was tore in a spot. can I just replace this or do I have to get a whole new bonded separator plate? and if so where can I find one? thanks

 

A little of the same problem, free wheeling in 1st going down hill.
consensus is blown valve body gasket. Fix is bonded valve body plate.

BUT

I understand this part has be obsoleted.
Keep us posted.
