My 1993 Acura Integra pops out of 5th gear around 55-60 mph. Sometimes I can put the car back in 5th gear only for it to pop back out. When the car will not go back to 5th gear, I have to slow down and put the car in 4th gear. Other times when I can not go to 4th gear, I have to pull over and stop, wait a while, then start over in 1st gear. What is the problem?
