i accidentally screwed up some things on my remote yesterday so i decided to reset it to be sure everything was ok. when i did the reverse quit working on my lst2. i read my manual and halfway understand it. i have got the controller to back to where i thought the reverse should work. i went in system mode and under AUX it is saying 2P. the A button is no longer adjusting the brakes or the fuel mixture but it still wont shift into reverse. there has only been 6 tanks run through it so i wouldnt thing the tranny should be messed up. other than that it runs fine. what can i do?
