AT OIL TEMP flashing

[cardoc]

vegastriguy,

Your problem may be remedied with a pan removal, clean the sump screen and flush/refill. If yours has a spin on filter, take it down and look for debris in it. Clean it out before you spin it back on. If you take the pan down and see a lot of metal, budget for a rebuild or replacement. Other wise, you should see improvement.

Thanks Cardoc...I will do that tomorrow....

Park the car for about 2 hours, crank up the car for about 3 minutes, kill the engine. Check my fluids. Oil still good, AT oil still high.

Are you checking the AT fluid level with the engine off?

I checked it both ways...with it on and off....which is correct?

Warm, engine running, in Park.

Ok, I just did it that way to make sure. My transmission oil level is above normal.

Unless it was overfilled, when the level shows high, it is generally a flow issue. You may want to have the cooling lines and trans cooler flushed when you do the pan drop. The trans cooler portion of the radiator can clog up and restrict flow which will cause a chain reaction back to the transmission.

I believe you may find a clogged sump screen since it acted up when warm and went away after it sat a bit.

If the AT Oil Temp light is flashing, shouldn't there be a trouble code stored in the TCM that could help localize or identify the cause?

This thread might help identify the code, or codes. Many of the codes relate to open or shorted connections to solenoids, which could affect the way the transmission functions.
