    Ok, yesterday moring I was driving to school and I wanted to make a light so i gave it some gas, the light truned red and when i came to a stop there was a whole lot of white smoke. It cleared up right away and I know it came out of the dipstick tube and landed on the headers. What could cause this? It only does it when the engine is cold in the morning.

    Check and make sure the vent is clear. Usually, the tranny only does this when the vent is clogged or its overheating. ......possible torque converter failure... ??? slippage equals heat... which boils the fluid, it expands, and has to go somewhere... good luck with that [​IMG]

    I second the clogged breather tube. In the morning, when the tranny fluid is the coldest, it needs to get up to N.O.T. which would produce a gas. Since the gas can't get out the breather tube it forces the fluid out the dipstick (and not out around the seals which is good).

    Ok, where do I find the breather tube? Also, Does anyone know what the length of the dipstick tube is? Is it 27"?

    GM started using a locking dipstick for the auto tranny's in the early 90's and retrofit it as a recall on late 80's trucks. Fire would be my main concern...and the locking dipstick would prevent the spillage. I'd check the vent first though.
