White smoke coming from under the car after driving 5 miles on the freeway.

So.. im getting this white smoke coming from my undercarraige after i drive on the free way, i have a feeling its coming from my transmission. its stops smoking after i stop driving on the freeway and just go around town. i have a automatic tranny that working on getting repalced for a awesome 5 speed.

Any one know what this could be or what i can do to prevent it from hapining again?

it just started doing it again, but not on the freeway, mabey an exhaust leak before the Cat?

my engine is running strong, at normal temp and sounds normal.

Most likly some kind of oil burning.. I see you have a blower? any chance it has a oil feed line coming from the engine oil pan??

get underneath could be your rear main seal or the seal on the tailshaft...

Im pretty sure its the transmission pan gasket that is leaking, any one free tonight?

yeath my seal on my tranny is leaking and i have the same problem i have to pull that dame tranny again for the 3 time to change the seal. goodluck

Sounds like a transmission or rear main seal leak. The oil is probably hitting the exhaust and smoking off. Changed both the Main Seal and Trans Seal on my car this year.....GOODBYE SMOKE!!!

a tranny tail shaft leak would be easy to spot look under the car around that area for caked oil/dirt in a line around the end of the shaft

Just beware. Automatic tranny fluid is very flamable stuff. I had a fire once from tranny fluid leaking on the exhaust.

 

[ears]

ooohh that sounds rough!!
good luck man!!

sounds like somethin you should alwayse consider doin when you put in a new clutch checkin out that rear main seal!!

i would hate to pull all that crap apart just for a little rubber gasket!!! god that would suck!!

"white smoke " may be Steam! and not smoke. Usually oil or tranny fluid is blue smoke, white is almost allways steam (water vapor).
Look and see if your radiator fluid is low, also ck your oil, if it's like mudd or chocalate pudding, its water in your oil and you have a head leak.
