Blowing tranny fluid

I've got a 2001 Bravada with 140,000 miles on it. New transmission was installed 4 years ago & last year the tranny was service while still under warranty. We just got done driving round trip from Cleveland, Ohio to Orlando, FL this past week & on our drive down the car was smoking. I looked under the car & there was transmission fluid all over. It's all blown back to the rear end & is all over the back gate. Didn't do it the entire trip but most of the time. I checked the fluid level while hot & the fluid level was above the full level, almost like it was topped off BUT, it wasn't. It didn't do this at all in the 3 years of having the new transmission. Car was running great leading up to the trip. Pulled the car into the garage to check where the leak is coming from. I pulled the car too far into the garage & decided to just roll it back instead of starting it(neighbor complains about noise at night) different story, ANYWAYS with the car in "N" it wouldn't roll back at all. Got it up on stands & the fluid is coming from the end of the rubber hose above the right side of the transmission.

I think you overheated the transmission. It's happened to me, too. If so, your fluid will be cooked, but with some trans service, it may work normally and be just fine.

Given it's been hotter than Heidi Montag's bathtowel recently, I am not surprised it overheated. A long trip in hot weather, at highway speeds, with AC cranked, full-time 4wd drag, and possibly lots of weight in the car lends to high operating temps.

Imho, drop the pan and clean it out. Change the filter and refill with fresh fluid. Disconnect the cooler return line and start the truck. Allow old fluid to drain from the line. Refill the trans, and reconnect the line.

You may want to consider installing an aftermarket trans fluid cooler, and having the trans checked for a faulty torque converter lock up solenoid

Thanks, i was thinking the same thing about the over heating. Going to change the fluid this week.
