I dont know why any of the respected tranny rebuilders never tell anyone this, maybe for job security.........
It is very important to replace motor mounts when making good power, especially with our 15+ year older cars that have worn mounts.
It is a good idea to replace them with stiffer mounts as normal mounts or worn out mounts will cause engine shake, and when it shakes it releases and applies engine load on and off fast. This can cause gear chatter with high load! It like taking an air impact to your gears, not cool.
Just thought id share this to help our commnity a bit as it seems these tranny's can get the best of us!
