The transmission shop finally got my JMOD 1998 era tranny complete and in my 1994. When roadtesting, it ran like a rapped ape right up unitl the RPM gauge stopped working and everything went to hell in a hand bsket. Does this problem sound familar to anyone. Would it be something as simple as bad connections on the transmission electrical wiring or does some other evil gremlin lurk in the shadows. This car has sat for at least a year before I got it and all I ever driove it was up onto a trailer and around the block when I got it home to determine the old treansmission was junk.
