[QUOTE="TBItoy, post: 724593, member: 1384"] -trans will go into "limp" mode and not shift at all/only shift into 2nd gear. Basically it thinks it's slipping all to hell when it sees the output speed much slower than expected. -If you program the tcm for double low range, and wire up the low range switch, it will shift correctly in double low. If you are only using single low, but have the switch on, it will see the tailshaft speed as much faster than calculated/expected and basically think that you are going way faster than you actually are, and it will never downshift correctly/only downshift at WOT/and then only sometimes... (think coasting down a big steep hill with a trailer pushing you, that's what the computer is "seeing") -you wouldn't need a kit to do what I posted, just drill/tap the stock tcase adapter for the vss, and put a tone ring on the shaft. -That kit you posted a link to is for putting the vss in the back end of a 700r4/old style 4 bolt 4l60e (click on the installation PDF and it shows where it goes in the actual trans case) OR, if you only care about/want auto shifting in high range, you could run a manual override and switch the solenoids directly to shift gears manually. You can build your own switch panel, or use a cool little unit from raddesigns [url=http://www.radesignsproducts.com/rail-controller.html]http://www.radesignsproducts.com/rail-controller.html[/url] Raddesigns also sells the auto/manual selector switch kit, and a potentiometer kit to directly control line pressure on a 4l60e. Lots of options with an electronics transmission. But the easiest is to put your vss on the tailhousing and let it run in "2wd", ignoring the transfer case module and controls all together. Oh and your auto tcase has 3 vss too. only 1 is for transmission control/feedback though. the other 2 are inputs for the transfer case controls/auto 4wd business. :JRich: [/QUOTE]
