While accelerating (my 2002 GP GT 127K miles) to pass at about 70mph recently, I had a sudden and temporary power loss and heard almost a squeaking sound from engine compartment. I then
noticed that if I took my foot of gas pedal, rpms would immed drop to near 1000 rpm...and when I then tried to moderately accelerate, engine would race back up to 3,000ish rpm before producing any more acceleration (and rpms required to travel 60mph are now about 3,000 rather than normal 1900ish). There is no check engine light. On the plus side, car seems to drive normally in 3rd gear (albeit w/less fuel economy etc). I do expect to go to a tranny shop to get a def diagnosis, but does this just sound like a simple loss of 4th gear? Could I expect to get a lot more miles out of the car if I just keep in 3 from now on, as cost of fixing wouldn't be worth it
Thanks for any insight.
