I am having a problem shifting if I turn the A/C on ( after 10 minutes ) or if I drive for 30 min. turn the engine off and come back 10 minutes later and drive.

Does the Mustang have a clutch cable or is it hydraulic?

Do you think that it's a clutch or transmission problem?

Any suggestions?

1998 Mustang GT
5-speed
115k miles

 

what kind of "shifting problems" are you having?

 

It's very difficult to shift, like I'm forcing it into gear

 

sounds like a clutch problem(cable)
