Okay my rancher want show any gear on display just flashes 6 times esp also it want change out of first gear. None of the es up and down want work and it jumps when u give it gas in reverse... Will someone please help me through this please... If i have to bypass or rig something to change gears i will thanks...

 

Just checked on-line and code 6 is angle sensor faulty. If I remember correctly these are expensive, and tricky to fit as they need pre-loading on the 400AT, so watch what happens when you take the screws out that hold the old one in. I'm fairly sure it springs through about 1/3 of a turn, note which direction, the new one needs to go in at the same angle and is then turned back in the opposite direction, so the screws can be fitted.
