So FFR says these 0.6″ spacers that came in the 6-speed kit go between the transmission and the mount. Doesn’t work for me.
In this pic, the transmission is resting on the pan (on the chassis). The transmission mount bolts aren’t long enough to accommodate the spacers. No new transmission mount bolts in the kit either. So used some other long bolts for testing. The spacer probably needs to be more like an inch or so to work. So maybe this is another 04 6-speed incompatibility.
So modified the chassis (Zach’s way).
Also cleaned up the tail housing with the freeze plug. Great idea Kurk!
