I had this same problem. Changed the drive motor out and had the same result.
We found the Access 3 module was bad. Our tech put in a good used one and flashed it.
This solved the problem.

Customer Service First, fixing comes later
I am having same code issues... I pulled the M2 motor/drive unit assembly off as it was turning really slow if any at all while wheels were raised and steer tires straight. I could turn the drive unit very easily and had no binding or slipping with it after having the motor removed from whole assembly so I figured the trouble was with the motor and replaced it. I'm still getting the 760/759 codes. Any suggestion's??? anyone

Do the above and if the tires are turning about the same speed (steer tires in the straight position) check both the encoders in the analyzer ECR1 and ECR2 if the counts looks right then see how much slack you have in the drive unit (truck blocked up)
If everything looks good go to F27 in features and disable it, drive the lift to ensure everything is working right.

Left and Right drives are not syncing up. Block truck up with tires off the ground and see how motors are turning when selecting travel.
