Hey everyone I’m new to the forum and new to the pathfinder world. Just purchased a 1994 3.0 SE on 31’s. Seemed to run well when test driving and all. Got about 20 miles down the road And it started shifting out of 1st at around 3500 rpm but cycled through every other gear flawlessly, and would manually shift from 1st through drive perfectly and then the check engine light came on, so we ran the diagnostics via the ecu under the passenger seat and it showed an oxygen sensor and more importantly a speed sensor. Fast forward a couple days( next time I had to work on it) replaced the speed sensor and now it won’t shift out of 1st at all. Had a buddy who knows far more than me helping out and he got a volt meter and we pulled the speed sensor back out and spun the gear while he tested it at the cluster and it seems to be the Output from the cluster to the ecu meaning I need a new cluster. Anyone else out there have these issues? Any help/advice would be greatly appreciated. Thanks!!!
