Hi maybe someone can help me with this problem I have. I own a 1991 Pathfinder VG30 engine with the RE4R01A Tranny I have had problems since I bought the truck with it staying in lock up. The tranny failed (Clutches) I rebuilt it replaced all of the solenoids in it during the rebuild, also put in a shift kit. I still have problems with it staying it lock up. This is how it works, Shifts good to 2nd, Drive and OD, after a while 2-3 miles it will go in lock up for about 1/4-3/4 mile (sometimes it goes in and out before staying in) and drop out and will never try to engage again unless I switch it off for about 30 seconds and once agian the proccess starts over. whether I switch off while coasting on stop and switch off and start again. I bought a book when I built the tranny and I check the computer and it told me it had a bad revolution sensor. I have called several nissan places and some do not even know what that is. The only other thing that does not work is the Tach? The only thing I gained by the rebuild is replacing the worn clutches which I think this maybe caused by the lock up problem. If you can help please let me know.
Thanks, Ted
