I also heard that putting on a poly tranny mount with stock rubber motor mounts is bad for the transmission. I believe it considering the shifts feel firmer, so more stress is being applied to the tranny. Im going to LTs and poly motor mounts this weekend, I'll throw in an update on the new mount feel when its done.


Using polymounts on an Automatic transmission with stock rubber engine mounts up front will crack the extension housing on the tranny along with putting aditional stress on different parts that connect to the Torque converter ..
Adding poly motor mounts up front only buy a little more insurance for preventing that..
Any automatic making decent power that goes to the track often needs a tunnel brace mounted torque arm to take aditional stress off of the transmission..
