Tremec had sealant on it from the factory, so we put sealant on the replacement, too.
As you move the shifter handle around, the shifter’s bottom ball applies force to the shift arm, which actuates the forks and other things inside the transmission. It’s all black magic to me. I just want to make vroom vroom noises.
The cups/bushings are shown for reference. On the bottom of the blue adapter block are posts that will press into the shift arm in the transmission. The hole in the center of the adapter receives a part of the sequential shifter assembly, and the slot receives another part related to the reverse actuation. More magic, I assure you.
They really want a tight fit, and they are not kidding about needing to sand it. There was no way it was going in without sanding. Barry gives it some love using the buffing wheel. He barely took off more than the anodized finish.
