I have a "99" Sable that runs and shifts fine until it gets hot, then it stays in 1st gear until I turn AC off or stop it for an hour to let it cool off. If I run it with out the ac on it is fine also. I have changed the fluid and filter in the transmission and also installed a trans. cooler with no luck and also this problem only happens in town, when I am on the highway it runs and shifts great. Any suggestions?
How do you know it's getting hot ? What is the Temp gauge showing ? Do the cooling fans work ? Have it checked for trouble codes an scan data checked .
It was however the correct thing to do in changing the fluid and filter - that's the first suspect. No no it wasn't , the correct thing would be to take it to a qualified repair shop . Hooking up a professional type scan tool an viewing data , inputs to transmission control module , ECM/PCM - engine computer etc. The control module controls shift solenoids -which shift the transmission . You could have 1-2 shift solenoid shorting when getting hot . View scan data is the only way to see this problem .

actually just installed in fron of the radiator it should come with some kind if zip ties or something to atached to radiator the look for the transmission cooling lines most of time they are like 5/16 to 3/8 of an inch thick and they are atached on the side of radiator, then get transmission cooling roober line and continue the lines to the cooler and also get 4 hose clamps to install on the hoses ends

When was the transmission rebuilt and was it done by a shop with a warranty? I have yet to see an alternator cause damage to a transmission but there has been stranger things. If the alternator was hooked up wrong or a wire was left off, the system could be loosing power to one of the ECMS. Or one of the ecms could of been damage if the wrong battery terminal was hooked up. That I have seen. For the moment, it sounds like the car is in limp home, which is a safety feature by the manufactures that does not allow the car to be driven. Are there any lights on, check engine light, transmission light ect when the car is running?

got me racking my one ameoba brain cell this one,and i cant think of anything that i have had like this sort of problem,except once with an old petrol commer truck many years ago,and the problem here was the inlet maniifold was loose.Now as this is obviously an auto then when the engine "kicks " as its dropped into gear then something is causing it to cut out .Now i suggest you check manifold nuts are tight first.Then check all the wiring connectors onto the sensors on the engine ,pulling the rubber covers back and checking the wires are connected and none broken or and undue bending that could have broken the copper inside the insulation.Then check the actual connectors themselves ,ensuring they are not broken or burnt.If you cant find anything then call out your local mobile mechanic as he will no doubt have a plug in tester and when engine cuts out it should show a fault??But if it is one of these sensors then iam at a loose end as to what one would cause this sort of fault because when i was at college we were still taught how to white metal and scrape the big end and crank bearings.Not to walk around with white coats and plastic pervert gloves and all looking like bill gates type nerds who can only talk about gigas and OBDII also wouldnt dream of changing a clutch on a big truck on the side of the road with only a trolley jack and a couple of pieces of 4x4 and a chain.Let alone sort out the truck driver and give him a right hander for burning the clutch out in the first place.

I had the same EXACT problem on my 2002 Sable. Freaked out thinking I needed a transmission.
All I needed was a tune-up. When not firing properly, sensors "take over" to compensate.
Check plugs/wires...you'll be surprised...I sure was!!

Motor getting hot doesn't necessarily mean the transmission is getting hot. It was however the correct thing to do in changing the fluid and filter - that's the first suspect. The stopping of shifting is baffling here.. The overheating should be unrelated. Your cooling fan (if it's working) doesn't provide nearly as much cooling in town than the air flowing through the engine bay at highway speed. Is it consuming any fluids ? Any leaks ?
