5MGE A/T Can it burn trans fluid?

[jsbenami]

Well just as I am getting progress towards selling my 85 Celica Supra......

I am wondering if these cars when equipped with a automatic transmission can burn transmission fluid? I know on some other makes things can un seal and leak into the vaccum system that will suck in automatic transmission fluid producing a smoke as the vaccum sys sucks it into the cyliner chambers. Deos this ever happen with this car?

Reason being is that when it idles for about 20-30 min white-ish smoke puffs out the tail pipe, but there is no discernable coolant loss, no bubbles of a BHG and no overheating or signs the like oil/coolant cross contamination.

The auto trans was services a number of months ago and reads a bit high on the stick, can overfilling cause this too? The smoke smells slightly acrid and sweet. When you drive the car it go's away. If you sit in traffic a real long time it will puff sometimes when you take off. I suspected it was oil because the car eats allot of it, but it should smoke on startup ect not after idling for a long time.

Sorry, but trans fluid won't find its way into a supra engine. You are burning engine oil. Yes, idling for a little while (even a long red light) can cause oil to be burned, especially when you accelerate. Sounds like your piston rings are worn, and valve seals too.

Drain and fill back up with 4 qts of 20-50w oil, and 2 bottles of STP (or walmarts engine oil treatment, blue bottle, it is STP in their bottle).

This will help slow down the oil loss/burning. Don't bother with those phony additives that claim to stop leaks and oil burning.
