Tranny Mount?

my tranny shifts hard on some days when its colder. im guessing its cuz the mounts have contracted some what. when its warmed up it does a bit better. anyway, its not a screwed up tranny i already know. it is the mount thing under the tranny. it looks like a rubber rectange bumper type thing. its on my automatic. its right on the bottom. i noticed it was deteriorated some and would kinda like to replace it. my other mounts seem to be good because the engine doenst move much as it would if they were bad. anyway. has anyone replaced this tranny mount or whatever you want to call it?

Damn dude. You have been here a while. This is a noob response, SEARCH!

i already did a search man, thats why i posted. search didnt help what i want to know. guess i should better restate my question. has anyone replaced just the tranny mount and fixed the problem? im going to save doing all mounts for when i get either the motor rebuilt, or if i get a motor swap which will require all new, and probley custom fitted mounts.
