Transmission mount part number

I hadn't had any luck with the search function bringing anything up as far as part numbers for my car but it looks like my tranny mounts are fudged. Would this part number from gmpartsdirect be the right one ?

I can look into it, but I'm going to need to know what transmission you have.

They use the same database that your local GM dealer uses.

20814995 Is the GM mount specific to the 2.0 LNF turbo SS HHR 2008 thru 2010. That other number also fits but is for the Cobalt variant, it will fit.

You're welcome. It would be a good idea to check the others also. As one starts to fail, it puts a strain on the others.
