Hey guys I am new to this site. I recently purchased a 4x4 1996 R50 Pathy. I am having serious problems with my tranny. My CEL is up and it is faulted due to an, incorrect 4th gear ratio. I have searched everywhere and have tried almost everything with no luck. I have checked the MAF and TPS, they are both good. I took the pan off the tranny and found that the solenoid pack was bad in the tranny. I put a new filter in and still have no luck. It seems as though the truck is shifting right on 1-3 but it wont shift into 4th. At around 45mph my RPMS are at 2700 and on occasion will drop to about 2400, then once I reach 50-55mph my RPMS are up to about 3200. I know that my 4th gear is not bad because before I started working on the truck(before new fluids) I could sometimes get it to shift and it would run great. Please help me out, I am really gettting frustrated with this car. I was really excited to get this pathy and it seems as though it is turning into another used car nightmare!!
