Does the T case bolt up to the 4l60? How does that work for VSS with PCM?

the tcase is the gm 6 bolt style np208 so it will bolt up to the adpater that came with the 4l60e. I was going to mod the tcase for a reluctor wheel but i may use the jags that run pinionmount vss. I do not like the aa kit that puts the vss between transmission and tcase as computer does not know correct speed in 4 lo

Check out Dakota digital's in line vss. 8000 ppm and ultra easy hook up.

for the 4l60e you have to have the 40 pulse per drive shaft turn. Only way is a reluctor mounted on tcase or differential. I have thought about fabricating a kit for the np208 which never came with a vss.
