My brainless son submurged his truck, my old truck in the lake.

What does he need to do to get all water out of auto tran's other than pulling the pan and draining .

 

[parcher]

Hopefully he hasn't cranked the engine over with water in the trans, this would pump water to place it will be hard to get clean. Drain and re-fill any comonent that was under water, road test breifly and check the color of the fluids. water in oil will turn to an emusion, easy to spot. Keep flushing any water fouled parts until there is no more v evidence of water then do it one more time to be on the safe side. Pay close attention to the axles and transfer case if equipped. If the cab went under pulll the carpet out before mildew sets in (this is a very difficult smell to get rid of).

Ditto on what parcher said. Keep changing all the fluids until they are clear/clean. The fun part is getting the water out of the hubs in the rear end, the only way to do it is to pull them and knock the seals out. Otherwise, if there is water in there, it will stay.

He drove it about 6 miles before I spoke to him, fluid was comming out of fill tube, so we know how much water was in trans. He is going to change and and drain until fluid is clean.

Those new trans flush machines work well for that type of stuff. They hook to the cooler lines. They do a pretty good job at exchanging all the fluid. Then I'd take the pan off and change the filter. Maybe you can find a shop close by that has one. Many of the instant oil change places have them now. Cost about $80. 00 or so last time I checked.

I'd change the diffs a couple of times too.

I have heard that an auto trans that is driven enough to get warm can have the water in it break down the glues that hold bands and clutches together. This was some years ago and things may have changed since then, maybe someone who is in the field can comment. Getting every bit of water out of the trans would seem like a must do.

 

[JoeBioDiesel]

I've seen coolant make clutch material flake off, but not water. My biggest concern is that it will make the fluid foam, which creates all kinds of problems. The driver would probably notice soft shifts and a higher stall speed on the converter... at least for a little while...

All other suggestions good . If you pull the trans pan and drain oil and new filter replace pan ,fill start ,idle open trans return line from radiator let fluid drain as some one with funnel and good supply of fresh trans fluid pores it in to the fill tube at same rate of out flow ,watch as fluid flows out to see change in color torque converter will be darker than the new fluid and or contain water , Make sure to do good check for sand ,mud ,water ,in the collection Pan ,jar , that was clean to start with. Running the Eng and trans with clean fluid to heat the fluid and dispense water is a must but you have to get most of it out ,If you have a exhaust brake use it at idle to heat Eng ,and radiator after replacement of fluid . Use WD 40 spray to get water out of connectors and junction ,fuse , other electrical connections , when all is done drive the truck to dry as much as possible and change fluid one more time or more . LOL Ron Bissett in Metro Louisville KY P. S AS Parcher, said use nutral and be sure to block the wheels for safety.

Just make sure the trans is in nuetral if you do the running flush deal, there is NO flow to the cooler in park, thet's why the dipstick says to check fluid level in nuetral.

Thanks for all the help, the captain of USS Laramie removed the interior, flushed the diff's and drained trans. Will be regretting trying to get the Dodge to swim for awhile.

Flush the transmission a couple of times. Had a friend burn down his Chevy after only changing the fluid once, and then heating the water/ATF mix up to boiling point where it came out of the dipstick and landed on the headers. ATF is cheap compared to a new truck... .
