1989 V6 2.8L MPFI. Auto. Just about every time I'm driving, if I hit the gas with any kind of authority, I get this loud thump from under the shifter hump. Its a little further back, like under the armrest even. Its fine till I stop again, then it happens as soon as I give it even a little bit of gas. I can hit the gas so it doesn't happen, incredibly gently, but the cars behind are pissed off then LOL.

Always happened like that in this car (had it for 4 years now). The severity of the thump, (which can be felt, and heard), is directly proportional to how hard I hit the gas.

Any clues? Is my tranny jumping around down there?

 

Check your transmision and torque arm mounts.

 

yes it sounds like a trans mount to me

 

 

classic trans mount.

i bet it shifts a lil hard when you go into reverse and back to drive again too, huh?

 

btw, trans mount is about $12... i reccomend a poly one...

its just two bolts on the trans, and one or two thru the crossmember... first time might take you 20mins.. after that, its a 10min job.

 

Oooh, thanks guys, and yep, thats exactly right Mrdude.

I'll look into it this weekend.

Recommendations on where to get one?

 

You can get stock replacement or poly transmission mounts at just about any auto parts store.

 

go to your local autozone, checkers, napa. any one of those will have what you need

 

Thank you very much

 

i had that same problem all summer and we couldnt find the problem until i went to the place where i got my exhaust done and the guy showed my it was the trans mount i should have thought so because there were pices of it hanging under the car. btw my replacement part was only like $6.50 but now it drives like a compleatly diffrent car
