hello CatDW20 ,any fix is not going to be cheap ,after fixing cooler ,drain all the oils from trans and fill with oil ,and change filters often ,anybody have other ideas ? ,bruce oz


ex info--- from a member on acme -quote - if it was hot when it let go the water is gong to be at the top of every thing. needs to
get oil in it and run it asap but not get hot enough to steam the water. then water will settle to the
bottom and drian it off
-if he needs to run it then he will have to drain the bottom every day till it
comes out... Filters will not catch water in oil..flow is to fast

Thanks! My son in law bought this D8, which is in really good shape, other than the transmission issue.

The problem is that the fluids are real milky looking and foamy and stuck to the sides of everything. Just wondering if anybody has any ideas how to flush the transmission and torque converter, with as little cost as possible, without using many gallons of good oil to flush the system. Would anybody recommend using diesel to flush it? I don't want to mess up any seals, etc. Or, any other ideas to get rid of the milky, foamy fluid?

By any chance are there any words in the Operations and Maintenance instructions relating to compartment flushing? Once oil and glycol are mixed through gears or other rotating elements the cleanup becomes quite difficult and any remaining glycol will destroy the film strength of the new oil.

As a wild guess I would use one of those air driven atomizers that could spray a heavy diesel oil fog into the compartment to rinse out the goo. The tool is sold as an engine cleaner. This is what I am describing, http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=97014

First you need to correct problem. Likely cooler. Then you need to add about 1/3 Byutelcelloslov or what ever you can buy today in the oil. Run engine untill trans is warm but don't load it up. Then drain it all out, fill with new oil TDTO4 or equivilent and change filter. Be sure to drain from all plugs, torque bevelgear case at center and both sides near steering clutches. Then after a days work change filter again. To clean rad, drain and fill with water and some laundry detergent, warm the engine up and flush with a hose in the rad filler. Continue flusshing untill clear water comes out and no scum is left on water surface.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
