Lemme guess, your cruise and a/c don't work either. What about your tachometer? If these things have stopped working then I'd say that your crankshaft position sensor is either bad or has bad wiring attached. I'm hoping that's what it is, as it's a lot cheaper to replace that sensor or fix the wiring associated with it than it is to get a pcm. It could also be a bad ground to the pcm.

Call down to Sun Coast Transmissions. The owner of that company was in the process of working on the 98's so the transmissions would work "right"..... he may have a spare he will sell you... just be prepared for :spank:

the 98 - 02 have the 47RE trans... the 24 valves have many more inputs to tell the trans to shift... stay put... what ever... the only real input the 98's have is the TPS (throttle position sensor) which can be a PIA... and best to do the "home made" TPS

Good luck :thumbsup:
