Ditto.
If the valve body switchout allowed it to shift, and (at the same time) caused a failure for line pressure to rise, something is likely amiss in the checkball, separator plate, or valve body gaskets.
Without having it on the bench here, I could not begin to guess. I still think the root of the problem is a new transgo valve binding in the valvebody. They are know for it in the 93 model year.
Thanks for the help. Will a 92 valve body work? TCC wiring?
Any 88-92 valve body will work, with the matching separator plate, and checkball arrangement. Wiring is no bighie also, but you would need both wiring diagrams side by side to confirm wiring and pressure switch combinations. I have not done it in a while, but do not remember it to be terrible difficult.
If replacing the valvebody is an option, PATC has a stock of brand new 1993 valve bodys. Assuming they have not sold out by now. They had alot of them, so I dont think it is likely. I only suggested changing valvebodies if you wish to elininate the transgo kit. I know a few guys that owned 1993 model year transmissions that had enough, and removed it.
