Hello, liberty lovers! <insert bald eagle here> 
I have a 2004 Liberty, V6 3.7 and 42RLE gearbox and a transmission problem.
It has never failed, neither the forward nor the reverse gear.
I went on vacation to the coast, traveled without problems about 250miles. A couple of days after arriving, I left the parking lot at home, put it in reverse and it worked normally.
I entered the beach in low gear, with the whole family, with no effort. I didn't do dunes, I just went in.
When I was about to leave, I put it in reverse and it didn't engage, the truck didn't move.
Forward, no problem, everything was fine, including the overdrive.
I came home, arrived without any problem.
When you put the lever in R, you hear a little noise and the truck moves slightly (just like when you put D and moves slightly without stepping on the accelerator. That smooth movement where you can stop the vehicle with your hands). But when accelerating in R, the truck does not pull back hard or add speed. If I engage double and/or low, it doesn't change either.
I took it to an automatic gearbox repair shop, they scanned and computer trows P1776, P0736, P1790, P0706, so the mechanic told me that the problem was in the valve body, that I didn't have to think much about it, just replace it and that was it.
P1776: Solenoid Switch Valve Latched in LR Position
P0736: Reverse Incorrect Gear Ratio
P1790: Fault Immediately After Shift
P0706: Transmission Range Sensor Circuit Range/Performance
Since I was closed for the whole month for vacation, I brought the refurbished body from the US and replaced it. I added about 6.5lts of fluid, but the situation didn't change. The forward gears go smoother, but the reverse gear still doesn't work.
I did about 30miles from where I did the work to replace the valve body to where I live, freeway mostly. The funny thing is that it hasn't given any error codes yet.
Thanks for reading, any comments would be appreciated.
Meet me me yesterday, doing the thing...
