Last nite will cruising about 40 mph I suddening saw in my rear view mirror what looks like smoke coming out the back of the car!! So pulled over real quick an stopped to see wtf is going on. I smelling trany fluid as I got out and looked under the car and saw a puddle of the red stuff. I got back in and backed the car up to confirm it was in fact trany fluid - looked under the car again - nothing dripping - check the fluid level - it's fine!!
So I finish the errand and go home and checked the fluid level again - it's a ok - wtf?
Drove it this morning - no puddles, no issues!!
Anyone got a clue to what happen??

 

Very glad this story didn't involve what I thought from the subject line... sorry, no ideas in diagnosing the potential leak, unless it's PS fluid?

OD clutches are the weak link, and the smallest, so they go first. Most guys who tow with a 4L60 in OD have experienced this. You may try flushing the trans fluid (its most likely burnt) and replacing the filter. this may buy you some time.

have you heard the hard parts line? it's what a transnission shop uses to bone a newb up the wazoo foward and backwards

you have the most common auto trans on the planet, yet to estimate the rebuild $$ the trans con has to disaasemble and inpect the hard parts because he's not sure of the cost of a sun shell, planetaries, or a clutch drum

even though you're at his little shop of horrors, with the most common transmission ever made he has to tear it down to estimate

GM srta is a good value, as they come with "HARD PARTS"


I agree 100% with what you said-

I should have given some details on the car:
The car is a '94 - 94,000 when bought it from a Chevy dealership last Aug and the trany was "resealed" 2 weeks after I bought it - the Chevy dealership did the work, because it started leaking all over the place - I wished I had my "smart" hat on when I agreed to having it done - should had just gone with a "factory rebuilt" unit - but they probably thought I was concern about keeping it "numbers matching". Probably would have a warranty of some sort at least.
I've had another car do this many years ago ('73 GTO) - just once and the car was nearly new!!
