i have a 95 Z28 for some reason my tranny is only getting first and second gear it was just re done 3 months ago but if i drive it first thing in the moring or let it sit for awhile it will get 123 no od also the car has a bad hesitation after it is drivin about 8 miles or so could this have something to do with my tranny or vise versa any help would be great after i stop at the first red light it will only get 12 till it sits again
