I need to change my motor mounts/engine mounts. I've already replaced the front + rear trans mounts and filled them in with 60A polyurethane. But now the others need to be replaced. I have a 2006 GTP 3.9L V6 w/ manual transmission. It is hard to find part numbers and reliable info through google, gmpartsdirect and rock auto.
The part numbers for the front and rear trans mounts are:
I think there are 2 more mounts? One on the right of the vehicle, and 1 under the battery tray? correct me if I am wrong. There is also the "absorber" (22708438) does this typically need to be changed too?
I have found the part number 22708448 (side trans mount) but I am unsure if this is the left or right, as on some diagrams I am looking at it shows another very similar looking mount looking more on the right side of the car but they never have a part number for it. Specifically I am referring to this diagram:
Any help would be appreciated. Thank you.
Look around here: https://www.gmpartsgiant.com

The first one is probably the better of the two, but it asks for details about your car - such as transmission - that plugging in GTP doesn't answer. Also, is your car a 2-door or 4?
For parts, you need the engine mount (passenger end) and transmission mount (driver's end) plus the absorber you mentioned.
Since they are derived from the same engine block, I think the mounts for the 3.5L motor (LZ4) should be the same as for your 3.9L (LZ9) but I can't promise that. (To be clear, the LZ4 was offered in 2007, not 2006. But I think the 2007 parts may fit. The 3.5L motor offered in 2006 was the LX9, a substantially different motor. Sorry if that makes things confusing.)
One GM part # I found was 22708433 for the engine mount, passenger side. The GM part numbers can be plugged into lots of places - ebay and Oreilly, for example. They will cross to aftermarket parts, and, on the GM parts websites, you will also sometimes see newer GM part numbers listed with the notation "replaced by".
I think the p/n you found, 22708448, is correct for the transmission mount (driver's side) .
The absorber p/n you have, 22708438, is for the manual transmission. I found 22708437 for the automatic.
Take a look at these other sites, and see if that helps.
