I have a 92 Bonneville SSE 3800 V6. About 2 months ago the tranny suddenly started having shift problems. We were on the freeway driving when we got off I suddenly noticed that it wouldn't upshift until 3500+ RPM's were hit and overdrive no longer works and 1st also doesn't work unless I manually shift into it. I ahve check all fuses in both the fuse box and convenience center and nothing is wrong there. Also the electrical connection on the forward side of tranny is connected but makes no difference when I take it off and drive it. Fluid is also freshly changed any ideas would greatly appreciated. Thanks.
