Reported at 37,000 miles, June 2014 CrashInjury

Driving from out of town and all of the sudden rps ran high and trans would not shift. It would catch finally and then slip out had to drive it in 1st gear. Had it rebuilt lasted 1 yr and now back in shop! Having it rebuilt again. Very frustrated with this vehicle. I have had to replace just about everything on it at least once some things twice. Very poor made vehicle. Please look into the transmission problems.
