I have a 1995 quadrunner 250f that the transmission locked up in low and high gear. It drives in super low. It engages but will not move. Any help appreciated.

 

my 1992 was like that all summer,it was stuck in high,someone told me to jack up the front end and grab one of the wheels and trurn it right and left i kept doing this and trying to move the shifter and it shifted to low,try it can,t hurt

 

I will give it a try.
the quad was being driven at the time and it locked up .
