Hi,
I have similiar problem, my 1998 RS only work in fwd, but I have the fuse in because when I take it out it only shifts from 1st to 2nd and when it tries to shift into 3rd or 4th it justs revs no power to any wheels.
It has a 31711 ad800 tcm,is this for a 1998 2.5RS only?? Is there any other tcm I could put in that would work??:-\
Regards,AJS70
