just swapped the trans in my brothers 2003 1500 silverado. its a 4l60e. he had it rebuilt 6 mos. ago and it **** the bed again.i replaced it with one grabbed from a junkyard. took me q full day but its all set. now of course i get in it after i replace it, changed filter/gasket, and refilled it, i put it in gear and...nothing. no reverse, drive any gears doesnt matter 2wd-4wd just nothing. trans doesnt even feel like it loads up when i shift. also seems almost as if it wants to stall as its idleing in park a little almost like it had a lumpy cam. ready to tear out my hair, any ideas? thanks
