so installed my competition plus short throw shifter and almost immediately on my drive to work i noticed an increase of noise inside my car while driving. i can hear the engine from the inside differently, it doesn't sound like how it used to, it sounds different for some reason. (also when i installed the shifter i did a test drive and a 1st gear pull, when i shifted to 2nd gear, the gear didn't go in so my engine revved to about 6400-6500 just for a quick second or two till the RPM's dropped back down) don't know if that helps. when i got home, i started checking everything out and noticed that my large dust boot wasn't installed properly so i got it to sit the way its supposed to with the seal around the base of the shifter and the second seal on the floor panel and the third one where the chrome stick bolts to the shifting unit i also put the provided zip tie on there... does anyone have any suggestions? Thank you all for p input but i know for a fact it was after the shifter install

did you drop the tanny support bracket when you installed it?

i installed it on my 11GT but had exactly the same problems. I made sure the rubber shift boot is mounted all the way to the shifter base (you have to stretch it around the square hurst shifter base). The boot still didnt perfecty seal the opening in the console so i glued it. Finally sealed the entire inner console with thick layers of dynamat extreme. Worked perfectly. Even my old stock tranny whine cant be heard anymore.

no i didnt drop the tranny support bracker, i just unbolted the old shifter and dropped in the new one from the top.

by9568840--- you glued the rubber boot to the shifter and floor tunnel opening? how will you take it off in the future if you need to? what kind of glue did you use? what is dynamat extreme? and what do you mean the inner console? i was starting to worry it was just me but apparently its not just me haha so thats good

I would check to see if you perhaps mistakenly cross threaded the single forward shifter monting bolt (not the linkage bolt)
