hi, i have the 42RE transmission in my truck and got the tranny flooded with water. i dropped the pan on it, replaced the filter, let it drip for a few hours, n sprayed it as clean as i could with brake cleaner. after topping atf off i than flushed the tranny 3 times untill atf came out the machine was red. everything seems ok for now but i think i may have damaged my overdrive gear. does anyone have any advice on what to do besides replacing/rebuilding trans? is there anything esle i can do to save the overdrive gear?

before this happened, sometimes in the OD gear, i could here like a grinding noise. when i let my foot off the gas, it would go away. hasnt done this yet since ive done the work to it. it feels like when it shifts in OD, the RPMs are about 4000 more than before. for example im going 55-60 mph, the RPMs would be around 1300-1400, now its around 1700-1800. havent driven it on the interstate yet. so cant tell u how it rides at high speeds.

no iwasnt that deep. my driverside was deep enough that water was coming in my cab. i kept my truck running when i was stuck if that gives u a idea. i drove it 2day n it drove good, shifted good. just that OD gear with the different rpms now.
Two ways I can think of that water got into the trans - first way was the one Sully5981 describes; the other way is a leaky capillary tube that sits in the radiator and is part of the radiator trans cooler setup - if that tube is allowing the water/coolant into your trans, you will need to replace/repair the radiator or bypass the radiator based trans cooler for a fully external trans cooler.
