Water in transmission?

Pulled the plug to check to check fluid level today and out runs a light tan goo. Guess I should have checked it while the motor was out.

Anyone with a T98 ever have this happen? Any suspect place water might get in?


Thanks, Greg

 

H2o will run right down the shifter cane, past the boot and inside. Esp bad w/no top, no boot, and they sit out in the snow like here in the East. See it more often than not on ones I've parted. Get too much in and it freezes and cracks the case.

 

T18

 

Has not been exposed to weather at all.(Not sitting with trans exposed) So what did you use to clean it out? Did you reseal everything including the front seal?

 

Looks like creek in your avatar. Air breather on top of tran. also.

 

I drained it , poured gas in there ,ran it, and started with fresh oil.
probably not the right thing to use but it got the job done

 

Gasoline is an explosion risk, as well as not being a lubricant ... kerosene or diesel would be better, but still...

People have been known to run motor oil in these transmissions; If I had to add something other than gear oil, I'd run the cheapest motor oil at WalMart for a trip around the block, then drain. Not a recommendation per se, but a suggestion of something that has to be better than gasoline.

 

Thanks for the replies. I think I'll give the motor oil a try.

 

If it's been sitting for long periods of time condensation can build up enough to cause that too.
Automatic transmission fluid is high detergent and a good lubricant. Works great for flushing out manual tranny's. I wouldn't run it long that way but just for flushing purposes it does a good job..

 

I was wondering if it could be condensation. It had not been driven for several months while I got around to the motor swap.

 

Looks like a lot more water than could be accounted for in condensation.:?

 

Have to agree with CJ5aTim, thats a lot of water for condensate. I would suspect water got in the trans through the front bearing retainer if the jeep has ever forded water. There is no seal in the front bearing retainer on stock T98's.

 

That was cj5/442's picture, not mine. Not sure what caused his.

I have not done any fording. The jeep sat for almost 7 months until I had time to get it running again. It always had the top on and was also tarped if it rained or snowed.

I went with nickmil's advice and used the ATF treatment today. Seems like it worked pretty well. I'll keep an eye on it to see if it happens again.

 

did you park that thing in a lake?
or did you fill it with milk as a joke?

 

SIDSCJ's comment is totally correct, and cracked me up.

Here in today NH, I just came inside from putting a space heater under the jeep - the transmission is frozen solid and has the vehicle locked up tight.

Not for the first time... I need to put a rain diverter on the shifter one of these days!. It's my cutdown 'doodlebug' CJ used for working around the farm, and the trannie is not so good anyway.

Is it possible your water was remaining from something a previous owner did?

Not in my case. All fluids were changed about a year and a half ago.

 

You can make a "no-frills" rain diverter from a plastic funnel. Get on that the neck is a little larger than the shaft. Split the funnel with a razor knife. Holde it on with a hose clamp. Seal the seam with RTV. My $.02.

You can also do a lot of fabrication out of thick plastic soda bottles and a heat gun. Have made temporary filler caps for windshield washer fluid out of the neck of a soda bottle. Heat the plastic until pliable, and keep the heat away from the neck. I done carefully, you can sill use the screw cap.
