Twm short shifter problems

LukasC

So guys i bought the twm shirt shifter and installed it myself then reinstalled it again because it didnt feel right. Im having concerns with it. When i drive it has a hard time switching gears stops in neutral then goes into gear. Shouldn't it be smooth from one gear to the next? Also it is grinding the gears even with my foot all the way down on the clutch and idk why its doing that. I loosened the linkage bolt to see if that helps. It didnt. So if anyone knows about what i can do or what the problem is that would b great! This was my first time installing a shifter on my own car was an easy install and everything lined up correctly but if yall have advice please let me know. Otherwords i may be selling this
