Thought I would bounce this off you guys before taking it to the dealer. I have a 99 SC300; after driving it hard for any length of time, then coming to a stop, I notice whitish smoke (not a large amount, but enough to catch my notice) coming from underneath the middle of the car and if I pop the hood, from the tranny tunnel area. I have checked the tranny fluid level both hot and cold, and it seems very high; I have attached a pic .
Could it be that the tranny is overfilled and that's what is causing this issue? The car still shifts fine; I did notice this happen when I first bought it and drove it back to GA from SC. I took it to the dealer on two occasions, once specifically for them to check the tranny since the tunnel seemed hot in the cabin and they said everything was fine and that was normal.

Any help appreciated!

check your heater hoses at the back of the engine, one may have a pinhole in it.

It can be oil leaking on the exhaust.

Hmm I had that issue but I am running a 5 speed and it ended up being my rear seal on the transmission. GL

Well, took it to the dealer this morning, and it turns out that there are seals leaking oil onto the tranny. Nothing horrible, and it's not my DD, so I'll probably wait till my next oil change to get it done. I did decide to go ahead and do the timing belt, water pump and cam seals (those were leaking as well). Expensive, but I plan to hold on to this car for a good long while
