A/T no pressure

[TurboAnything]

My car decided it hated me today i was far from home with no cell phone and my trans took a dump. It was fine 2 days ago started slipping a little during cruise and taking off from a light. Then today i made it almost all the way to work and it started slipping real bad then nothing just neutral. I let the car cool down for 10 min and it drove ok for about another mile and started slipping again. Now the car is sitting in a parking lot and will not drive i pulled the cooler lines and nothing comes out of them in drive. When i first start it it will move then it just starts slipping again.


I have now pulled the pan to find ATF with shavings in it and 2 small chunks off steel nothing real important looking. Now i took the filter and ran some solvent thru it and it did not seem clogged but for some reason the pump is not pumping?

Now mind you this trans was perfect 2 days ago. It has fresh fluid and no leaks and i tried all this with the tcu unplugged so its not the tcu.

Well you may have answered your question. Metal shavings and 2 hunks of metal but no pump. Did your fluid run low somehow? Some way? But I'm thinking the pump took a dump. And maybe the tranny was good 2 days ago, so WAS my alternator . These things happen as I'm sure you're already acustomed to. The problem with A/T's is they are SUPER sensitive to specific operating conditions. I have actually seen instances where even using the wrong fluid burnt up the reverse band, clogged up the 2-3 port in the valve body, and started to take a toll on the crescent pump in about 5 days.

The fluid was just autozone ATF+4 about 2 months old was never low. I did notice the trans seemed to get real hot on long drive like 1 hour or more. Now why do you think the car will move when cold but stop 10 sec later?

The only things that come to mind are (A) filter bolts have been over-tightened causing the pressure regulator valve to bind (very easy to do), (B) filter is stopped up (put a new one on even if yours "isn't" stopped up),(C) You've been given the wrong aplication filter (my transmission parts supplier regularly gives me filters for the 2wd n/a F4A22. Ask for a filter for a 92 3000GT N/A) or (D) your fluid level is too low (the fill sticks are notoriously wrong. Fill while idling in neutral up to 1/4 in. above "Full" mark). The metal shavings in your pan are probably from the thing running without fluid pumping through it. Don't forget your transmission uses that fluid for lube as well. Good luck.
