if it is a three speed automatic it is probably the TCC solenoid sticking. On the front of the trans (pointing towards radiatoer) there will be a square plug that you can unplug. if that fixes the problem then it is TCC sol. DO NOT DRIVE ON LONG TRIPS UNPLUGED THIS IS TEST ONLY. WILL CAUSE TRANS OVERHEATING AND DAMAGE IF DRIVEN EXTENDED PERIODS . but if it does correct the problem you know what is wrong.
It will NOT cause transmission damage in early 90s or older cars, only when you get into 96-97 and older cars with overdrive transmissions.
So, just look in the front of your transmission, its a 4 wire plug, unhook it and you should be on your way.
Low pressure line Larger line running from compressor
Might be a bad heater control
It is clogged and needs replacing or your engine is running very rich and is dumping unburnt fuel into the converter where it is being burnt.
Pull out the transmission dipstick (red handle) just as you would for checking the motor oil, but with the engine running and the transmission in neutral or park.
Had the same problem with my 92 cutlass ciera. It turned out to be ac compressor. Probably the clutch.
Add it the same place you check it, through the dipstick tube. Check the level with the transmission hot, in park, engine running, on level ground. Use only Dexron fluid. Do not overfill!!!!!
My fan will not come on, even though the diagnostic computer says its running at 220 degrees. We turned the fan by hand to see the electric motor was shot! $40 at parts store.
Quit running after its fully up to temp? Restarts after it cools down? Check the spark when it does it, could be the ignition control module.
sounds like the ignition control module
I would suspect a bad alternator and battery, have them both checked at the parts store. A car with a fully charged battery and a bad alternator will run until the battery is drained and then quit.
to cool the coolant in the engine
