Water in rebuilt Transmission... Why? Where?
 
Well I took out my transmission, brought it to a friend who I work with who owns a transmision shop, He Rebuilt it and installed a shiftkit, boosted the line pressure, and put on a new billet torque converter. When i Got it back I installed it drove it about 300 miles and brought it to him, and he checked the fluids, and there was a white paste on the end of the dipstick.. Water?

So he realized he messed up by leaving the transmission outside on cart while waiting for me to come pick it up, and while it was outside, he went out to grab a lunch and it downpoured. So as he got back to shop he moved it inside, and thought nothing of it until now seeing that white paste on the dipstick, When we noticed the white paste or water we changed the oil, figuring a little bit of water got in through the dipstick hole. Now a week later I just went on a 400 mile trip next state over and back, and checked the fluid again, and its back. But worse. theres more of it then the first time, and it seems to be built up inside the dipstick tube as well.

Where is this water coming from?

Im thinking condensation, but this much, that fast? I did lengthen the Breather air tubes for the transmission and transfer case up into the engine compartment ziptied to the dipstick tube for offroad purposes.

This is a 2005 Jeep Grand cherokee with the 5.7L Hemi. K&N cold air ntake, Custom Catback magnaflow, Mickey thomspon wheels..

Thanks for any thoughts

I know its easy to come up with negative thoughts. He was being honest about the water. At first we couldnt figure it out, and it came to him, crap.. I F*Cked $p.. Lets change out that oil. I told him theres more, now and worse, and hes stumped along with myself. Hes gonna take a look, and change the fluid for me this week. Theres no way, there would be this much left after what we cleaned out the first time. Cuase its 2-3 times worse. Im thinking overheating, and condensation...


I saw a Bulleting from jeep, about something to do with condensation from the evaporator somehow leaking down the dip tube and getting into the tranny.. But that doesnt apply to this jeep.

Thanks

Maybe a couple or 3 changes will get it all out. There are a lot of places for it to settle and hide.

Darn... Expensive oil!!! Yet, maybe a hopeful answer...

Get it on a flushing system It'll continually pump oil through the tranny till all the bad oil is out.

Otherwise... change it... drive. repeat. then hope it doesn't cause any other issues.

Don't flush!

You will get all the last vehicles crap into your new trans.

Drain the entire system (trans, torque converter, lines, cooler...all of it). Then check all your seals and sensors.

I gathered that its his tranny and rebuilt the parts in it... rather than getting a "core" rebuilt tranny and built it up.

I could be wrong though... wouldn't be the first time :lol:

Some of this has been mentioned, but as Escape says, the only way you'll get "most" of it out is to remove and drain everything. Changing the fluid in the pan won't get it. The converter passages, valve body, servos, etc. will retain contaminated fluid. Also, the filters will retain a fair amount. If you continue to change fluid AND FILTERS without removal and draining everything, you may eventually get a good share of it out. The question really is, do you want to risk doing a fix that may lead to a premature failure on an item that you've no doubt spent quite a few $$$ on, or do you want to do it the right way?

Thanks guys.. but I don't think there was more then a couple drops of water to begin with. Could anyone tell me if the external cooler I know I have might run in series with one built into the radiator, or is the radiator a standalone unit? I don't have access to my jeep at the moment.. thanks..
