98 No reverse after bad rain storm.

[pbellone]

I have a 98 4X4 EXT 5.7L. I have been trying to locate a leak that is getting water in my blower motor. Today, after a significant rain storm I went to the store and heard a bang like a bad shift. It did it a few times on the way home. When I tried to backup in my driveway it worldn't move. Selected reverse, the engine rev'd alittle and nothing. Forward seemed ok but no reverse. I removed the blower and found the bottom full of water.

This issue seems electrical with the tranny. 104,000 miles and this truck has been perfect. Not a problem. Is there a control box/wiring in the area around the blower that may getting affected?

Transmission has to come out,broken sunshell and this is a common problem with the 700R4/4L60Es.The aftermarket hardened sunshells do break and I know one transmission shop that has seen this.

Don't like that answer. I Googled it, I hate it more. I wasn't doing anything rough when it happened. Can it be something else? (this is the denial part) Pete

Check the condition of the fluid also,if it is pink,your good.It is inside the transmission,with the broken sunshell and can be fixed without a rebuild if you are lucky.I do repairs on these with broken sunshells and never had one come back yet.
