No tcc lock up after engine swap

Stumbling at random?

The truck hasn't had cats for years now so that's not it. I re did all the gaskets so I know it's not a vacuum deal. All my grounds are clean, made sure I did that putting the motor back in. The tcc won't even lock up when I ground the solenoid out either

Stumbling at random?

New engine problems

not sure if this is the right place to post but long story short my motor locked down so I swapped a new one in. Same motor l31 vortec 350 from a suburban. Well I'm pretty sure I plugged everything back like I got it out but now my AC controls won't work. Like the blower won't come on. Also...

Weird 4L60e shifting

Yeah that was the first one I saw. It doesn't describe anything like what I got goin on. It's weird. I'm leaning towards getting a new TPS and new valve body, filter and fluid change and just being done with.

Weird 4L60e shifting

okay so I ready through everything on this trans that I could. I have a 97 extended cab z71 350 and 4l60. Well the problem is sorta intermittent. It will shift pretty hard into second gear from first under regular throttle but usually will shift smooth if I give it more gas and let it shift...
