I know this thread is 3 years old, but I'm hoping that RivnGrn can let me know how you solved the problem was since I'm having the same issue. I had the motor rebuilt and it works fine, but just parks high. The guy who rebuilt it says there's no adjustment for the park switch, but there must be someway to change it or it wouldn't be out of whack now. Anyone have any advice (other than taking my chances on another rebuilt motor)?
