    You may want to change your engine mounts to poly at the same time. I've heard that just replacing the trans mount to poly can cause breakage, as in broken transmission case. Reason being that the engine mount being rubber can flex more than the transmission.

    I'll third the "do all poly or all rubber" quotes. The adapter "feet" in particular are very weak, if the engine can twist but the transmission mount can't, somethings gotta give, and often times its the adapter.
