Hard shifting in 95 GP

[RG501]

after my 95 GP warms up to normal running temps, it will start to shift hard. its not like a little bump but a hard jerk. i dont know how to fix it. my dad said that "hard shifts are good" and by adding the Lucas Transmission treatment it will "wear the metal in the transmission faster" i think hes wrong. is hard shifting normal like my dad says or something that should be fixed?

Hard shifting can be good i think if the transmission is made for it, but if u have the stock transmission on there, like mine ( i also have a 95 grand prix gtp) and for a while my transmission was shifting real hard, so i did a fresh fluid and filter change and it shifts very smooth now.

[RG501]

so you think if i put new fluid in it, it would help it shift smoother?

Yea, if u have access to a lift its really easy, but u could just do it with a jack. it is a pain to drain the transmission fluid b/c there isnt a drain plug or bolt so u have to loosen like 6 bolts and let it drain out of one end. Go to any local auto parts store like autozone and they'll prolly have a filter in stock and it took a LOT of transmission fluid to put back in when i did it. the guy gave me 6 i think and said the was plenty, but i had to go get 2 more quarts to fill it. Autozone will probably have like 3 different filters that u have to pick from, there should be a number on the bottom of your transmission pan that will specify which one you need. Mine is 4T65E and the filter for it was only 12.99 .

sense im no good at takein apart cars, do you think the guys at auto zone or someplace could do it for me?

[twstice]

I dont think autozone does that, but im sure any auto repair shop would do it, ...it shouldn't cost too much for labor i wouldnt think, because it's really simple, and there isnt anything in the way of it that has to be takin off or moved.

[RG501]

ok. how much do you think it would cost to fix? and is it true that useing the Lucas Treatment would wear down my transmission faster?

i was drivin today and i found that if i take my foot off the gas right before it shifts, and then give it gas after it shifts, it wont jerk at all.

[twstice]

Im not sure how much it would cost, i've always done all my fixes my self, but any auto shop should be able to give you an estimate. i wouldnt think it would be much. And i have heard the same about the Lucas Treatment, i dont know from experience, but i'd rather not find out, i just take their word for it, lol. Also about how u let ur foot off and get back on it, i was able to do the same thing, im almost positive the transmission fluid and filter change will fix ur problem.

[RG501]

ok. so i guess i'll just take it in and have them check it out. is doing the foot thing i said bad for the transmission? cause i almost makes it seem like im driveing a manuel shifting car.

[twstice]

I dont think the foot thing would hurt anything, but just dont floor it when it is shifting real hard like that, lol. and be real easy on it till u get it fixed.

my 95gp was experiencing the same problem. i did a filter and fluid as well. and then i got that 100% fluid replacement, (torque converter, cooler, lines, etc) and got it filled with that full synthetic stuff. i dont feel a thing anymore.
