Torque converter leak.

Robert Schaad · Jan 26, 2020

For those that do not believe any thing I say, I spent 20 years in Germany and always drove MOPAR. So I ran into many problems that I had to fix because there are no NAPA, or other parts stores there. You must fix it yourself. 1976 Aspen R/T, with a trans leak. The leak only happened when driven, not at an idle. WHY? What is it. One day on the Autobahn, my trans stopped working leaving a huge puddle of trans fluid on the ground. I added several quarts since we always carry extra in Germany. Got home, Then NO leak. No leak for several days.
So the answer is strange. I replaced my transmission, since I had another one. Upon close look, I found a hair line crack in the Torque converter snout. So the leak was caused by the high RPM driving, which would cause the crack to open a little, or the heat of the autobahn driving to open the crack a little. I have run into some very strange problems while serving in the Army in Germany.

Hell, anything is possible..Bought a new trans from a well known company and it shifted fine drove out fine but sitting over night it would puke out all the trans fluid. Pulled it checked torque converter replaced the fluid and drove it the next day. Not a drop on the ground. Next morning it looked like a murder scene on my driveway.. Pulled it back out to check the torque converter again. This time using my micrometer I checked the snout size vs the pump seal... Well, all was good there. Then low and behold I noticed one of the pump bolts was not seated all the way into the trans. It would only leak when pressure sat on it for a while. They paid to ship it to and from them and fixed it.. But what a pain in the *** to pull it 3 times. And the car had an H-pipe.. Making it a royal pain in the ***.

Is it a 904 trans? Cracks are not uncommon at the pump drive tang slots. Turbo Action offers a thicker snout. However the stator support must be machined for clearance. You can also switch to an A 500 over drive pump and hub. It is not slotted

Had a '76 Volare with exactly the same problem - replaced two seals before I figured it out!

How did you find a 1976 Aspen in Germany? I say you should have built the ultimate sleeper - Hemi Trabant.

I paid 400 bucks for a beautiful orange 76 Aspen R/T with white bucket seats / console and a built 360 / 727 a number of years ago. thing ran flawlessly

I met an American that lived there and he had it in his shop for many years. He was going to rebuild it, but you know how that works. Here is how it looked when I sold it.
