rubber pads between transmission crossmember and frame

[85begalttype]

are those pads that sandwhich the crossmember to the frame all the neccesary, has anyone compared vibrations?, i will have a new trans mount.

I don't know if they are absolutely neccesary. My Olds doesn't use them. Why do you ask?

im doing a frame restoration and the frame im using doesnt have them, but my other car did

Not sure if necessary but every Fuel injected Gbody has them.

I've always wondered that.... I knew all TRs had them (84-87) never looked under an FI elky though...

I would say it may become a good place for false knock if it were to get a little loose. Just guessing, but any metal to metal contact would worry me for that reason only. I get some shift knock every now and then even with them in.

Are you sure its from Them?? Not a downpipe or exhaust peice?

i went with hr's new poly units - they are very nice compared to the old junk stock stuff...

Im not saying they are causing my knock, just making it known that it could become a source. I have not tracked my shift knock down yet. Only happens once in a while. I have the rubbers on my car, but was just throwing out a reason for putting them in vs. not.

+1 Very nice stock looking but better material.

As well as a few others.:biggrin: My 83 has them as well so I'd say most of the TRs with a 2004R had them.:smile:

I was wondering if it had to do with Buick making the car "cushy" and giving it a better ride. My wife's 86 442 doesn't use them and that crossmember is mounted directly to the frame. Very solid feeling car. Tried that setup on my 87 GN and it rode completely different so I put them back on. All of my hotairs had the pads and they all rode the same as the 87.

Monte LS has the same cross member bushings with the 4.3 FI's.
HI85WH1 it should also have the rubber bushings from what I have seen.
Buicks
87 307 no bushings
86 N/A 231 has them.
84 4 door v6 regal no bushings

Maybe it was just a V6 thing. Well I have a few cars here I can look at & that doesn't seem to be correct either. I'll do a little research.

Here are the original style & the HR styles

Isn't there 2 pieces, one above the crossmember--the other between crossmember and frame? Maybe needed for right height or correct alignment?

 

[GNeric]

Yes. The double pad setup has a longer metal insert in the top part. The single upper pad has shorter inserts. All of the ones I have seen are like this.

Correct... the 442 has a more rigid feel.. as does the MCSS...

IT may have to do with ride quality... gonna try and install a rigid mount xmember in the GN and see how it feels... (I think I have a spare) and from what I recall, the TR used the offest trans mount versus the straight version the other cars use...

 

[GNeric]

The crossmembers in all my TRs and the 86 442 are all the same except for where the trans mount is welded. On the Olds, it is directly under the trans and the TRs, it is off to the side. Not sure why the factory did this either. I didn't care for the way my GN felt with it solid mounted but I may be used to how the car rides. I may try it again later and let it go for a while and see if I get used to it. Hmmm...

Thanks for the info Eric. I was thinking about relocating my mount to center it better and use a better tranny mount. Now all I need to do is remove the cross member and relocate the pad.

I always thought they offset the rear mount to help reduce vibration and reduce the torque over.
