Hi All, I am new to this forum and figured maybe I could get some advice from everybody out there.

I have a 1995 2500 V10 4x4. It has around 220k miles on it. I was driving on the highway and started leaking transmission fluid. I was coming out of NYC so there were limited places to stop and I was kinda stuck on the road; over the matter of a couple miles, the truck became less and less responsive, as in it kept revving higher and going slower until eventually it just free revved while in gear as I was pulling over to the only shoulder I could find. The tranny was leaking fluid pretty steadily and I figured there was probably not enough fluid for the torque converter (its an automatic)...I don't think it was a catastrophic failure but rather a seal or something, but I really have no idea...

Any info on this would be greatly appreciated!

 

Tranny relies on hydraulic pressure to operate properly. Not enough fluid means it can't generate enough pressure for things to work as they should.

Dump some fluid in, start the truck. Find the leak. Fix it. See if the tranny still wants to do its job. Don't hold out too much hope there, though, stranger things have happened.

If it is leaking from the torque converter seal, trans is going to have to come out anyway..... and with the mileage you have on it, rebuilding it while its out would probably be a very good plan. You would be rather bent if you yanked it, fixed that seal, put it back in, only to discover you had to yank it again.... (and probably even LESS happy if you paid someone else to do it...... and lets not even talk about the wife's take on it, provided you have one of those.)

First things first though, need to find out where the fluid is leaking from, take it from there.

If it leaked the fluid out and was slipping like you said - it's probably done. Slipping = heat which kills a tranny in a hurry....
