Hello all, new here.
Problem with a 1990 4 cly auto, I was driving home from work the other day and everything was fine, then all of a sudden the trany went in to N and stay there. Fluid level is good, I pulled the cooler line and no fluid is pumping out. Any ideas.

Fluid level does not change and there is no noticeable noise. Could the shift switch on the front have gone bad?

Thanks for the reply.

ok drained pan fluid looks good no visable debries. Dropped tranny TC have fluid in it, pulled pump and all drain holes and ports are clean. Installed tranny and still acts as if its N, no wheel movement when gas is pressed. Also whit gas pressed I can shift from P to low with nothing happing. I wish I would of read your reply about the spring before I did the work. What else do you think. Its almost like no fluid is getting to the pump.

Thanks J

Ok guys, I pulled the electronic shifter contol off and cleand/inspected it, it is fine. Pulled the pan and knocked on eveything including the regulator valve. Soungs like the selonoids are working. The fluid looks good screen was clean. The fluid is just not getting pumped through the tranny at all.

Before I pulled the tranny the first time I could get the wheels to spen if I reved the motor up way up and it felt like it was shifting but I had to floor it.

After I dropped the tranny I swapped to another used TC and pulled the pump. After inpecting the pump all the ports and holes where clear and clean.

I put everything back together and now the wheels will not spen at all. When I tach it up the tranny does not do anything. I can shit from P to L when the RPM up.

I am lost. J
