Water In The Transmission!!!

Perhaps you know more than the oem and aftermarket engineers do. All heavy duty cooling set ups I've seen run the cooler line through the rad on the return side. All aftermarket trans coolers that I have installed for the last 30+ years recomend running the return through the rad. Where you live you don't see the -25 that I do. Trannys don't want to work when they are that cold. The cold side of the rad is still quite a bit warmer than the air. If the tranny fluid temp doesnt get uo to 160+ the moisture will not come out of it. Too cold tranny or hydraulic oil will make increased pressure wich will blow out seals, internal and external. Optimal lubrication and flow are not acheaved at lower temps also. Perhaps I know nothing but I've witnessed hydraulic failure from low temps. The co.I used to work for would not operate their cranes and forklifts in below -15f temps because of the damage that had happened. Special low temp hydraulic fluids are used in canada and the arctic .

Yes and no, many OE cars/trucks don't run a tranny oil cooler but a seperate unit. 1st and 2nd Gen Caravan's don't use a rad cooler, :thumbsup:

I run a large cooler in my Turbo van, thru winter, etc, no issues at all.
