Howdy I drive a 96 geo prizm with an automatic transmission. The car is a great commuter and a real work horse except for the fact that its been having a hard time going into 5th gear. Lately on the highway I’ll be going 70mph for 5 minutes on very high res until it finally shifts into 5th gear. Yesterday it took 10 minutes driving at 70 for it to shift into 5th!
Is this something I should really be worried about (as in transmission replacement?) or is it a smaller fix?
