4L60E Doesnt seem to move the wheels

[steve aleve]

So I am getting close to test driving my 47-54 3100 on an S10 frame with a 5.3 and 4L60E. I finished up the brakes and the engine starts and idles very nicely. The only thing I am unsure of is that when I jack the truck up and I go from park through the gears, it doesn't make the wheels turn as I would have expected.. For the most part they don't turn at all. They have turned a few times when I try but nothing consistent. Any thoughts? I have the TCC wire to a switch and I have played with that too and nothing...
