Walking through 4r100 shift linkage inspection and adjustments.
When I talk about positioning the unhooked transmission into NEUTRAL, I say to align the tic marks on the DTR. The tic marks are very faint, so they may be difficult to see. I should have suggested doing it this way in the video instead... Rotate the shift arm clockwise toward the rear of the trans until it stops moving. This position is PARK. Then rotate back toward the front of the transmission TWO CLICKs, this is NEUTRAL. And of course, make sure your parking brake is on and wheels chocked!
