transmission leak
Hello everyone, I just had my transmission rebuilt in January of 2006 by a local transmission guy here in Eagle Pass, TX. Well prior to having my transmission rebuilt, I would noticed on several ocassions pools of transmission fluid underneath my passenger side just behind the front passenger wheel. Well after having the transmission rebuilt, new fluid and gasket installed, I am still seeing the pool of transmission fluid. Where the heck is it leaking from? I cant tell whether is coming from the transmission pan area, but the bolts are tight. Please help..Marty

There are O-rings to both your modulator and the dipstick tube located on the right side of the trans. I tried resealing mine (new pan gasket and front seal) and when I put it back together it was still barfing huge quantities of fluid all over my garage, as it turned out it looks like it was coming from the dipstick tube. I repaired the leak by installing a muncie M20.

I am assuming its a TH 350 or 400...
Front and rear seals (recently rebuilt so should be OK here)
Leaks come from the O ring on the dipstick (easy to fix)
Seal on the modulator ( easy to fix)
The shifter selector seal (need a special tool unless you want to spent all day)
and of couse the pan gasket. There are stories of porisity of the housing too b ut this is not too common???
My TH 400 had a selector seal leak and a dipstick leak......
best of luck
