clunk sound

**Justin23454** · 11-09-2010, 04:10 PM

When I push the gas I hear a clunk sound, it sounds kinda like the engine slides back towards the wall, but I know its not, because we have looked at it while I push the gas. I know the tranny fluid is alittle low, but I dont think thats what is causing the sound. Ill try and get a video of it tomorrow so it will probly be easier. Also, it doesnt do the sound when it shifts through gears, just when I give it gas.

I would guess a bad motormount

**Tyler_LS1** · 11-09-2010, 05:12 PM

How many miles? I'm guessing it's an auto?

**Justin23454** · 11-09-2010, 05:32 PM

ya its an auto. it has about 120k on it, but this is the 3rd engine in it. The 1st guy replaced it so I would think they had new motor mounts, they didnt look that bad when we put the new engine in..

**Justin23454** · 11-09-2010, 05:56 PM

sigh, probly is the motor mount.... I shoulda just replaced it while the engine was out FUCK I dont wanna take it right back out to replace the mounts...............

Could it be the transmission mount? im thinking thats more likley if that is even an option

**Justin23454** · 11-09-2010, 06:26 PM

after looking more into it, Im thinking its the trans mount. It has that damn banging sound bad all the time, unless its in N. If I put it in gear its SoOOoOO damned annoying.

Then I would start there first, the tranny mount is much easier to change

**0rion** · 11-09-2010, 08:55 PM

it does sound like your tranny mount is the culprit.

**turyg ls1** · 11-10-2010, 03:25 AM

I agree with Tyler.. Its easier

**Justin23454** · 11-10-2010, 06:21 AM

Will a 96 trans. mount work on my 98? Ive been calling people but no one has them, they all say it doesnt show up.

**cpop98ws6** · 11-10-2010, 08:32 AM

82-02 are the same mounts. I went with the prothane mount, much better than the stock one.

**Justin23454** · 11-10-2010, 08:45 AM

ive called about 15 places around here and only napa had a 96 one. 18bucks. I think ill get that then order the other ones. Also does it matter if its for a v6 ?

**Justin23454** · 11-10-2010, 04:37 PM

yaaa was the tranny mount.

fixed for $17.39 and not hard at all to fix lol.

**Tyler_LS1** · 11-11-2010, 01:42 PM

Nice! Did you do a polyurethane one?

No I just went cheap for now so I could drive it, if I tried to get one of those I would of had to order it which woulda taken a few days

It's always better to put a rubber mount back in unless you are going all poly (motor and trans mounts).

Why? Just to keep the amount of flex similar?

x2

it can change your pinion angle slightly because the poly doesn't squish down like rubber so if you do the tranny and not the motor the tranny will be up a little higher
