Hi everyone, I have a couple of questions regarding the transmission mount on my 940 turbo wagon. Mine is soaked with oil and has 310k on it. Recently, I started getting a ton of exhaust rumbling noise and vibrations from under the shifter. The exhaust has no leaks in it, though - and is very secure at the transmission clamp. At first I thought it might be the original cat (which I replaced to no avail), then I realized that an exhaust bracket attaches to the back of the header pipe right at the transmission mount, so I'm assuming that's where my noise is coming from. So my questions:

-has anyone had this similar rumbling noise before and replacing the mount fixed the problem? Nothing like this is mentioned on the site or in FAQ, and I'm wondering if this is really the culprit...

-is it obvious when the transmission mount is removed how the exhaust bracket attaches? I couldn't quite figure this out when under the car. Does this bracket have to be removed in any way in order to change the mount? (no reference to this bracket in the FAQ or the site in general, as far as I can tell...)

-anyone happen to know the size of the nuts holding the crossmember and mount in place?

Many thanks!

Dear benfingland,

Hope you're well. At 310K miles or kilometers, the transmission mount does not owe you a penny.

A worn-out tranny mount will transmit drive-line noise/vibration to the bodywork, just as will worn-out engine mounts.

I believe that the tranny mount - affixed to the rear of the transmission - is separate from the bracket, attached to the transmission housing, that braces the exhaust pipe. A tranny mount (#1328900) has an MSRP of about $60.

The bracket (Part #6842241), that anchors the exhaustsystem to the transmission costs about $17 (MSRP). There is a clamp, that goes around the exhaust pipe (9135511; cost $7 MSRP). The machine screw - that joins the clamp to the bracket is item #985187 ($1.50 MSRP).

If I recall correctly, the attachments are pretty straightforward.

Hope this helps.

Yours faithfully,

Spook

Thanks, Spook - very much appreciate the part numbers! Yeah, it's 310,000 miles, not km - so I think it's certainly time to switch it out with a new one...
