1. daniel Says: my tranmission on a 2000 dogde durango 4wd with a 360 leaks at 75 to 80 miles an hour slow back down and it stops leaking when you run 80 for awhile it starts leaking and it comes out on the exhast making a lot of white smoke

2. bo Says: can't come out the exhaust on the dodge. can get on the exhaust if leaking on it from the front seal area if its over filled that's where the trans breather is on the front pump. no vaccum modulator on chrysler/dodge products they never used them. check ATRA.COM we love problems

3. paul h Says: The only thing I can think of that could cause that is a bad vacuum modulator on the trans which has a crack or hole in the diaphram and allows trans fluid to be pulled into the engine manifold vacuum port under periods of high engine vacuum.....such as freeway driving. Not sure if your trans has a vacuum modulator but if so, pull the vacuum line off and check for trans fluid in it.

4. ? Says: I'm really curious as to how you know that your transmission leaks when you're traveling at around 75 miles per hour.

5. Darrell Says: Don't go over 74.

6. Kenneth Says: check the seal around your trany and make sure its a tight fit and yeah how do u know it leaks going 75 mph down the road
