Lost Reverse suddently

Driving around in the mud after a big rain. Found a creek that was too deep, so backed out. It wouldn't do much in 4HI so I shifted to 4Lo and it backed out fine. Drove off and then 5 minutes later shifted to reverse - nothing. Slight whine, shift to drive and it pulls ok. Is this a common failure for reverse?

Have you looked at the condition of your transmission fluid?...

Yikes! I know where this is going....

Seems like I read this a few times a year. You got in water that was too deep, water entered your vent & ruined your transmission. You can try to flush & fill your transmission (few have had successful results), but most likely a rebuild is in your future.

I had tens of quarts of fluid flushed through my 32RH before it was clean and it's still ticking. Those things can take a licking but I'm not sure if your 42RLE has the same ability to take a beating, but there is a chance!

The next thing you'll want to do is extend the transmission breather up into the engine compartment. I have my zip tied to the top of the fire wall.

As mentioned, check the fluid and do a flush if necessary. Good luck!

I went through the same thing a few months ago. Pull the dipstick and smell the fluid. If it smells burned, regardless of the color (mine was pink/red), the reverse clutch plates are wasted. The only solution was a replacement or rebuild.
