My 1994 Supra TT was having smoking when I drove back from NC on Saturday. I was getting ready to install the downpipe, then I saw oils under her. It seems to me like the transmission is leaking oil underneath. :( It's the 2nd time after Toyota changed transmission fluid about two months ago, don't know if that's related. Help me determine where the leaking is...

Oil leaking underneath Supra

If it's the transmission leaking, approximately how much will it be to get it fixed?

Not good luck lately, thermostats/water pumps, now this...sigh..:(

Damn - sorry to hear about your troubles.....Let's see - is it dripping out or does it just let go (all of it) at a given time?

If it is a drip, i.e. you can see a small puddle after leaving it sit for a day or two - it could be a front main seal, or even a warped transmission oil pan. The seals aren't too expensive at all - the biggest part would be the labor. A new oil pan would be a bit more.

If it pours out after driving it for a while or gives out under heavy load - you may have a problem with your TC pump.

I'll keep thinking - let us know how fast..etc - it leaks.

Thanks for all your responses. My garage did have very very tiny of dried oil puddle on the floor. Anyways, I was afraid of major problem with the car, so I took the car to a shop and have them check today. The mechanic said it was the wrap around transmission oil pan that's leaking. It should be able to fix with small amount of money. He suggest me to change a gasket for the transmission pan. He also found out there are small leaking from the engene oil pan, but to do the whole oil pan service, it will require 22hrs of labor @ $75 per hour :eek: Kinda fainted when hearing that :( Good news is that the engene sealer didn't leak so far. I guess I'll do the transmission first, and see how it goes... Also, one of the Supra owner here said the gasket probably failed when the long trip heated up your tranny fluid, and he suggests me getting an aftermarket tranny cooler. Do I need it now? I am on stock auto tranny with DP, exhaust, boost controller. bcc and hardpipe kit.

Yeah, I'd grab a small tranny cooler for stock to BPU++, it's cheap insurance against the headaches you're going thru now.

Acutally, I have a small tranny cooler forsale $30 shipped (I had one guy interested but haven't heard from him in a day or so). Here's the thread:
