I'm not sure what's going on with the car, but when I put my foot into it it does this weird knocking sound just before it shifts. It's like someone's hitting the car with a hammer from underneath. It shifts nice and smooth in low revs.

I'm thinking it's either my tranny, or my rear end, or maybe just my cat getting clogged up making it struggle at high revs. I don't really know. If it turns out to be the tranny or the rear end, what's the best and cheapest solution you guys recommend that'd make sure it won't happen again?

 

sounds like the transmission mount has failed. there not to expensive, like 12-18 bucks, and easy to change.

 

phew, I thought it'd be much serious than that..haha. thanks man...you sure right? cause it kind of hesitates to shift too while making the knocking noise till I ease off the gas, and shifts really rough. One time it actually spun tires going from 1 to 2 pretty hard.

 

Don't get your hopes up

Your inquiry was about a knocking sound

crabby responded to what would be the high probability item. I've replaced a couple already in 18 months thanks to junior driving it.

As for hard to shift, that is another issue that you need to review after you inspect and or replace the mount.

 

I guess so. What does it do when the mount goes bad?

 

Turns out the mount was bad. $15.35 from Autozone, lol.

Thanks for the info guys, really appreciate it.

 

Unbelievable. Only been 10 days and that piece of crap already broke again.

The problem was fixed at first but then it started having the same damn problem again. I talked to a few guys at the meet and they were like "autozone? ah no wonder it broke so fast". I didn't even put my foot down in these 10 days...wtf?

Autozone has never been anything more than a letdown. Do you guys know where I can get a super-duty transmission mount that wouldn't crap on me again?

 

Energy suspension makes a nice one that is poly. alot stronger than the rubber ones. I sell Anchor mounts at O'Reillys and I have never had some one bring either the Anchor or the ES mount back broken. If you have an O'reillys give them a shot.

Most places carry the poly one, got mine at Advanced, seen it at Checkers. I'm pushing 500hp on my poly and it is fine. Think it was under $25

 

you got something else going on. either the mount was bad or you have some movement were you shouldnt. a poly mount is stronger but you will feel it. transfters vibrations better. motor mounts could be getting sloppy and letting the motor move a bit to much. did you feet this last one go. if so what happened? get a poly torque bar bushing i did that with mine before i got the tunnel mount for the torque bar. you feel that to. better transfer of power,,, more crisp anyways.
