Trans mount clearance

Should the Auto trans be touching the cross member. If not what should the clearance be. I notice mine is resting on it.

Sounds like your tranny mounts are collapsed. I know mine are bad but i still have about 1/4 an inch clearance on mine. should be at least an inch of clearance from what ive heard. add shims to level each side when replacing. Im sure someone could give you better specs than me as i cant seem to find much in pet or the wsm

Best of luck,
Jonathan.

Thank you for the info, looks like I need to do the mounts and shims, I did the MM's a couple weeks ago and looks like it put the stress on the trans now.

Not an auto, but I'd imagine the diff case dimensions are comparable:

Where did you get your mounts?

I know 928rus/928intl/928spec all have the part in stock. heres the part: 928.375.045.16

Jeff, did you have to disconnect the axles to get your mounts off? I also was told by someone that the driveshaft bearings usually are damaged by the fact that the mounts are collapsed, is that true?

You don't have to disconnect the axles to change the mounts.

I am still trying to figure out how anyone can reach the upper bolt on the right-side mount of a Rogerbox 928 ...

FWIW there were no shims on mine and no need to add them. Others have experienced the same. YMMV.

I removed the wheel and used a long extension with a knuckle joint. And still it was a PITA.

From what i was reading in the wsm, the spacers were only used as needed to make sure and level inbalances in the mounts were corrected. If the the parts are good, Id imagine no need but good to have a couple of each side on hand during replacement just incase.
