Reverse only works on flat ground

[wil bryan]

Hi all,
I have a 2006 Explorer XLT V6 AWD... Picked it up recently from a rear brake job and within a day or two of the work shifting into reverse became a hard drop, and it stopped backing up any level of incline. I can still reverse on flat ground, and everything else operates well. When trying to reverse uphill the engine revs, but there is zero movement.

• Is this a reverse band issue, a sensor issue, or a rebuild the whole transmission issue?
• Is the timing just unfortunately coincidental to the other work or should I be concerned the mechanic did something (Ive had so/so experiences in the past).

thanks in advance for nay and all suggestions, really appreciate all you who help the noobs like me!

CHeck the fluid level?

I cant see how a brake job would effect reverse, I think its just a coincidence.

Most of reverse problems with that transmission is due to the low band, only thing you can do is conform the fluid level is correct, if its full the transmission will most likly have to be rebuilt.
