Allison 5sp: Truck wont move.

[05chevy]

I just bought a 02 2wd that has been sitting for 1 1/2 years. Trans is a reman allison with 100k on it. The guy I bought it from said he replaced all solenoid in the vb. Replaced all wire harness to the vb. New NSBU switch and harness to it. Still wont move.

I tried hooking my tcm out of my 05 to it and still no movement. What could be the problem?

I'm guessing check line pressure first to make sure the pump it working?

Thanks for any help

Check the line pressure--

 

[05chevy]

The only code is p0700
The trans is full of fluid
And this is how the guy replaced 2 pig tails. Anyone have a harness for sale?

unhook the tcm or the round plug on the back of the tranny and see if you at least have limp mode...if not check line pressure. This would just be a real quick check.

that is some engineering if i've ever seen it. What's on top of the splices? Duct tape? or waded up silicone?

id start with checking fluid level, If you have a pressure gauge, check pressure, if not then id unplug the main harness, see if you get 3rd and reverse?



That splice job took a different kinda special!!!

That what happen to my truck last week, put a new NSBU switch and it still was in limp mode took it to advance auto to clear the code it wouldn't clear came back. So I threw in the towel and drove it to the chevy dealership and up being a ground wire needed fixed and a plug ended up needed replaced.

Nope, stunt double

Bump any suggestions?

P0700 isn't really a code.

It's an ECM code that tells you there is a code in the transmission.
