Trans Mount - go bad after only 15k miles?




my trans mount is bad (am getting slight vibration) and am surprised as that was changed only 15k miles ago (at 100k miles, now im at 115k miles) with a new trans mount but not sure the brand.
thought these were good for like 30k-40k miles before going bad...perhaps the shop installed a cheap replacement as they only charged me $25 bucks for the part (that was 2 years ago) and checking prices today and the Genuie MB part is like $60 and others like Lemforder are around $30.
Mine was replaced about 10k ago and shows no signs of tearing. It was either bad quality or you have something causing the Trans mount to prematurely fail.




Checking this Parts.com site it looks like engine mount is: 2202402717

if they are stiffer hopefully will help as I drive a lot in manual and the 1st gear and 2nd gear torque really makes the front of the car jump and am assuming the motor mounts and trans mounts get beaten up a bit from that.
