When accelerating from 3rd to 4th gear the gears slip and the car stalls for a couple of seconds and the rpm's go high and the engine reves up how do i fix this to make the car shift correctly?

Answer 1

you have a few opptions first thing did you add or remove any tranny fluid? i have a 2001 Pontiac grand am 6 cyl. 3.4 engine. it has no dip stick to check fluid the theory you shouldn't have add unless there is a leak.but in my case my whole tranny pan was empty no spills no indacation of a leak.except that when in 3rd and pressing the gas it didnt seem to want to go anywhere or the rpms would reach around 3000 but once i reached 4th it would drop down to 1500 and rides smooth. heres some things you could do if you don't have a dip stick to check tran fluid then just unscrew a corner of the tran pan and see if you do in fact have fluid even if you do i would just empty the whole thing clean off the magnet on the inside of tran cover change tranny filter.they say add 9 to 10 us quarts that's way wrong its 7 us qrts trust me i listen and addsd 9 1/2 and my car ran worst so i had to redo everything and i added 7 us quarts and my car is driving pretty good even though i ran the car with no tran fluid for almost a month.it stills runs a little funny when i first start it up in the morning.if that doesnt work for you then your vacum seal may be blowen and it is not getting enough pressure that could be why your rpms are going so high and taking a bit longer to change gears.but make sure you have enough fluid DO NOT OVER FILL LIKE I DID but if you add the right amount you will see the difference i did. iam not a macanic or English teacher iam just a person trying to save a buck. i learned threw trail and error but i got my car running and running good so i hope i can also save you a buck to
