1992 Ford Explorer Sticking - Drive Train & Driveline
Question: The automatic transmission was rebuilt about 25, 000 miles ago. It was functioning OK at first. Now when the transmission is cold it won’t shift out of first gear automatically. If I move the shifter from drive to second gear the car will shift into second, just fine. Move the shifter back to drive and it drops to first gear. To add some strangeness it does not feel like a full first gear. Stepping on the gas feel like first about 30 MPH @ 4, 000 rpm, but when I take my foot off the RPMs drop to idle and there is no pull on the engine. If I place the shifter in first gear the transmission acts like it is in first RPMs and when I take my foot off the gas there is pull on the engine. If I shift to second get the RPMs above 3200 RPMs and shift to drive it will shift to drive most of the time. Only on really cold mornings does this not work. Once the transmission warms up a little bit it does not have any problems. What can I do? Is there a temperature sensor on the transmission?
Thanks JJ

Technican: Did the rebuild come with a warranty?
Did the transmission fluid used match the specifications in your owners manual?
You can check for computer troublecodes, but I'd guess you won't find anything helpul. The following link will lead you to a repair guide which contains instructions-

Check the condition of the transmission fluid, perhaps the cheapest stuff available was used and a professional flush and fill with quality fluid is in order.
Owner: Hello,
I've re-opened this question at the customer's request.
Technican: As the previous tech stated, did the rebuild come with any type of warranty?You say it has been 25, 000 miles ago, so I am guesstimating that it been at least 6mos. to a year.I'm at question as to how much of a rebuild was done.Most rebuilds require the replacement of all clutch plates, torque converter, valve body if necessary and shift modulator.Any one of these will cause the problem you are describing.Fluids can and will be a factor, but it sounds to me as if the problem is a little deeper than oil.Check with the shop that did the rebuild to see if you have any recourse.In my opinion, any good repairer should be willing to help you if there repairs have failed at the amount of mileage you have since repair.In my state, there are several watchdog outlets(BBB, BAR etc.)that frown heavly on improper auto repairs and can actualy revoke a business license if any impropieties are found and proved.With that said, if it were me, I'd head back to the repairer and start asking some serious questions.
