Water in Transmission...

Sounds like we need to get it running ASAP and keep feeding AT fluid through it.

Wow, how nconvenient. Sorry to hear this.

Get that trans pan off, pull the plug out of the torque converter, let it drain down, blow out what you can, cooler lines back into the trans too. Speedo cable gear out, get in there with the blow wand too.

Step 2 put the pan back on and a filter, put the torque converter plug back in. Then fill it plumb full with Diesel Fuel. Water is heavier than oil, so the diesel fuel will displace the water.

Step 3 at your discretion: Pull all the spark plugs on the engine, loop the cooler lines together at the radiator. Crank the starter a few times to cycle the diesel through the torque convert. After you have cycled the engine without starting it many times, pull the loop off the cooler lines. Cycle the engine a few more times and see what comes out of the cooler lines in the catch pan.

Like I say Water is Heavier than Diesel so the water is going to the bottom of the pan.

Step 4 pull the pan and drain all the Diesel fuel out. See how much water settles to the bottom of your 5 gallon catch buckets, you will see it in the bottom.

Re-Evaluate, probably have to do one more diesel flush to get the water displaced out of the torque converter.

Now back together and fill it up with trans fluid and a new filter, plug back in the torque converter. Cycle the engine over with the starter many times then see what comes out of the cooler line. If looking pretty good, everone knows what a transmission transfusion is all about. Plugs back in and fire it up with the transmission transfusion machine. Start running the new fluid through it while it is running, transfusion machine has a sight glass so you can keep a watch on the fluid coming out and what is going in at the same time.

Crazy, Crazy. I would give it a try.

Good Luck . . .

PS: We have all done our own version of the transmission transfusion at our home shops. Pour the fluid in the fill tube as fast as it is coming out the cooler lines into the catch pans.
Get another pair of hands for some help.
