I have a 92 Z with a built 700R4. Recently I had to replace the VSS. Before I was able to get the part the trans started going from 1st to drive at about 3250-4250 rpm from a stop or when the vehicle went into 1st. With the VSS it still has no 2nd.

What could this be?

I am willing to do my own work and wondered if solving this problem could be accomplished without dropping the trans.

I would appreciate any technical explaination or detailed procedure for diagnosis and repair. Any manuals or websited that deal with getting into this trans would be appreciated also.

Please correspond by email if you can.

Thanks

Jim
