Sorry for the million and one posts. Never owned a 4th gen before and have plenty of questions. I have a 3.8 V-6 manual tranny. I replaced the trany mount because the shifter would bounce an inch or two. Well now its a little better but still bounce an inch or 2. Is this normal? I know these mounts are supposed to be hydrauliclly filled. Is this bounce normal? I looked for a poly mount but they dont make one. I put one in its place and it was short like an inch or so but if I put a spacer it would fit. Would that be a bad idea? I dont want to break anything but I just think the shifter shouldn't bounce that much... It didnt in my 85 v-6 manual firebird.

 

No it shouldn't bounce. When you say mounts are you talking about the engine or trans. It's not uncommon for the trans mount to break, so you might want to check it.

 

I just replaced the tranny mount, though it would stop the bouncing but it didn't. The tranny mount is brand new and not broken ... still bouncing

 

How exactly it is bouncing? Shifter/stick bolts are tight?

 

All the bolts are tight, the shifter is bouncing straight up and down, usually when you give it a lot of gas when your starting out or go over a good bump or pothold... as the torque arm is connected from the rear axle to the tranny. I was gonna get a poly torque arm mount but that would make it stiffer and transfer more up/down motion to the tranny mount and probally make it worse

 

GM has used basically the same tranny mount on rear wheel drive cars for about 40 years. I'd be surprised if the same mount for the 4th Gen V8 M6 and A4 cars was any different than the mount for the V6 M5 and A4 cars.

I also have never seen a "hydraulically filled" mount. They are hard rubber from the factory, with the mounting steel embedded in them.

What mount did you end up buying that is too small by 1"? What kind of "spacer" did you use?

The shifter should not do much more than move a fraction of an inch when the engine applies a substantial torque load.

 

Yeah these mounts are very different from the earlier camaros, I changed them out on my 85 and 89 firebirds before. They are a rectangular shaped mount. I took the original one out of the 96 camaro and it is much different. It is more round in shape and according to the auto zone web site and a few other parts web sites, it indicated that it is hydrauliclly filled. I tried to put a poly tranny mount that works for the older camaros and it would bolt up but it was about an inch shorter than the orginal in the car. So I went to auto zone and bought the OEM one and installed it but it still bounces brand new and it is not broken. I dont understand it. Is it supposed to bounce. I am thinking about putting in the poly one with a spacer but I just dont want to break anything if it is designed to bounce the way it does... maybe a design chance because of the 2 peice drive shaft? Here is what the autozone website says:

OIL FILLED (HYDRAULIC) MOUNT. RECOMMEND REPLACEMENT TO MANTAIN ORIGINAL EQUIPMENT VIBRATION AND SHOCK DAMPENING


And its not like they put the wrong part up, when I bought it, it matched my old one exactly and other part stores say the same thing Plus it says its hydrauliclly filled for vibration and shock dampening... (maybe why it moves up and down so much) Like I said it it dampens all that then If it make it more solid with a poly bushing... I dont want to break anything.

 

Oh yeah the poly mount I bought is sold by auto zone as well but as you see here It requires modification. This is the part number I bought but it did not fit... needed spacer. Its the ones under performance mount. I believe one of those was the part number I bought. I know G means a black mount and R means a red one.

Does anyones do the same thing? Any comments?

 

You seem to be basing your belief that the stock tranny mount is "hydraulically filled" because of what you read in an "ad". It says their aftermarket mount is hydraulically filled to give the same feel as the stock mount. Maybe their design isn't so good, if it still allows the tailshaft of the tranny to move up and down 2".

Does your stock mount look like any of these?

Injuneer, the one that was in my wife's 2001 V6 M5 Camaro was very different than those.

 

No the orginal or the replacement does not look like any of those. It was a round or oval shape where it meets the cross member and has a little metal tab that sticks out the side that a metal bracket attached to the mount after so much flex will hit the metal tab on the side to slow down the movement of the tranny after it moves like a quarter inch. Now from what I have seen at part stores the 98's and up can use the mounts you have shown in the picture but the part number for 97 and below is different? What year did the mounts in the picture you showed come from?

 

The orginal and the replacement both looked like this:

Oh yeah and this is another parts store that says its a hydraulic mount. Actually every store I look at says the same thing. Are they all wrong?

Oh and the new mount is not broken, I did check it and it is not making the thumping noise as if it were broken just moves more than I think it should. My real question is, that is it designed to move that much or will I have a problem if I buy a poly mount and engineer a spacer of the corrcet size to maintain alignment where it will be much more rigid. I don't know it it moves that much for a reason, like maybe the 2 piece driveshaft? The old mount and a new poly mount put side by side are much different in size. Maybe a 1/2 to 3/4 inch shorter on the poly mount, but the bolts do line up.

 

Anybody?

 

Ok just changed out the mount yesterday. It was broken but in a way hard to see. It was hydrauliclly filled. I guess these were installed on a select few years of V-6 manual tranny camaros. Mine being a 96 got it. Anyways After looking at the poor design of these mounts there is only just a little above 1/8 inch of rubber at one seam. This almost immediatly ripped open letting all the hydraulic fluid seep out. Im sure the orignal GM mount was better than the Kragen (made by anchor) mount I installed the first time. Well I did get an energy suspention poly mount. You have to modify the tranny bracket. Basiclly you have to elongate the already elongated hole so the bolt going from the bracket to the mount will line up. Thefirst time I tried to put a poly mount I used prothane. It seemed to be shorter in height than the orginal mount. I now tryied an energy suspention poly mount. They use a backing plate which helped it with the height. It seems to fit in much better. While the tranny seems not at the same height as it used to (when I shift into 2, 4 and R it almost touches the back of the plastic trim around the shifter) Every thing seems to be alright. It didnt really change the angle of the driveshft that much. Your probally talking like a half degree or less. The only thing I noticed was more vibration. I hope its not a problem. Probally why they had a hydraulicly filled mount in the first place, to dampen the vibrations. Just thought I would post my experence for others to reference in the future.
