Auto tranny shifts out of gear and free wheels. I can shift to N and back into gear and it will pull on level ground. Up an incline and it shifts out of gear again. Seems to be worse when cold but even after it warms up, it stops pulling over and over again. Then I shift to N and back into gear and we ride a little while longer. ???????? Anybody know a fix for this?

 

pulled the codes and got P1739 and P730. Any help with these?

 

3rd pressure swith in tranny is bad p730 code- Trans shift malfunction,could be anything from a bad valvebody to dirty fluid.
