Hey guys. I'm new here. I have a voyager that has a bad leak in the trans. A first it looks like a front seal leak. But it doesn't leak when the car is running. It doesn't leak when the car is in any gear and you hold the brake so the axle isn't turning. If you let off the brake and the wheels (and axles) are turning then fluid starts pouring out from behind the flywheel like it's a front seal. I have the car off the ground so I can crawl under it and see that is not coming from the axle seal. Like I say, you can put it in drive and rev it up and hold the brake and it doesn't leak till you let off the break and the axle starts turning. This doesn't seem like a front seal leak. The thing had the crank sensor brake off and I wonder if this could have broke a hole in the trans. Any ideas? It's not my van so I don't know for sure what exactly happened.

 

no one has any ideas besides Tizzy1? I think It's a hole in the bell housing.

 

By any chance is fluid pooled on top of the final drive and is the back hatch coated with tiny drops of fluid? That's the only experience I've had with a tranny leak on these wonder wagons. Turns out the front pump seal was bad and fluid was leaking past the crank sensor and on top of the tranny.

 

Yes there's fluid on top and the crank sensor was replaced. Is the front pump seal the same as the seal around the torque convertor. and did yours only leak when the axle was turning, but other wise not even a drop. i am going to take this apart in the next couple of days and will post what I find.

 

Got the trans out and yes there was a large hole in the bell housing into the diff. so the seal was good.

 

 

If you have a hole in the bell housing, Then the pin from the final drive gear may have punch a hole in the case. which means you need to either replace the case and switch all the internal parts into the new case or replace the transmission.

 

Mastertech, There is another option that the owner has chosen. Sell the van for parts.

 

That is the owner choice. I'm just giving the information on how to repair the transmission. Anytime and this goes for all members, If you don't get an answer to your question after two days. Send me a PM so I can help. Because I'm all over the forum.
