Glad you got it fixed.
I feel the TRD Pro knob is worth the $85 from Roman @ToyotaOfCoolSprings
It feels much better in the hand than the stock shifter.
In case anyone finds this thread in a search, the TRD Pro knob sometimes has this issue.
There is a small screw up in the top of the threads than can be tightened.
Just use a long handled Phillips #2 screwdriver.
