Thanks for the replies on this. I have had a chance to inspect the mounts. The lower motor mounts appear to be good and still bonded to the metal as well as the transmission mounts but I know looks can be deceiving. The top mount on the bellhousing / firewall had a lot of sideways slop to it and could be the problem so I ordered a new one and am waiting on it. If that doesn't do it then the next mount I'll replace will be the one for the transmission mainly due to ease of replacement. I'm keeping my fingers crossed that it's not the lower motor mounts as the manual says fan and radiator must come out, wheels must come off and the engine hoisted part way out to change them. What a PIA for two simple mounts!!
