So today i just got a shift **** and boot in the mail and wanted to put it on, so my current shift know was stuck ‘took it off already.’ I torched the underneath where the shifter and the **** connect then it got loose so i started twisting, mind you i had everything removed the rubber underneath the white mesh type **** so i could see from the inside to the floor on the outside. As i was twisting i saw that the whole shifter itself started to twist iself to the loose position. I grabbed a pair of vicegrips retighented the whole shifter “i think” and then proceeded to unscrew ****. Now say if the whole shifter itself was a bit loose then it should have been what would be the outcome? After i was done i turned the car on put it in gear and jt was fine till i went to stop, went into first then slowed down to a stop, then reverse then slowed to a stop, both times there was some sort of vibration ir something. But after that it was fine? for the rest of the drive im confused. I also had vdc off.
