HELP ME!! '00 1500 5.3 to 6.0 swap, now won't go into gear
I have a 2000' Silverado and I just pulled the 5.3 and put in a 6.0. I got it all put back together and the motor started and ran fine. The problem I am having is now it won't go into gear. I am using the old wire harness and computer from the last truck and it starts/runs fine with the 5.3 computer minus the SES light. I am also using the original tranny. Another wierd thing happens now. When I shift the tranny from "3" to "D" the starter engages. With the truck off if I hold the shifter in between "3" and "D" I can actually start the truck. I am at a loss here. I have checked all the wires I can and I can't find any that might be pinched causing a short and I have no idea why the tranny now won't work when it worked fine before.
I am in desperate need of help,
Adam

It has to be one of the two connectors that plugs into the side of the tranny by the safety neutral switch. Did you completely take the harness off? Those two connectors sometime gum up and do not seat properly when connecting them back up.

Did you put a 6.0 tune in the computer for the motor. There are too many different tables to chance running the 5.3 tune in the 6.0. Also, what year 6.0 was it out of? I did everything you just did last year and no trouble. I would first check what these guys said. Also, check all of your starter wires. Did you label your wires when you took them off?

Are you talking about the nuetral safety switch? If so I forgot to mention I had to replace that. I broke it trying to pull the plugs out. They were stuck in there with something that resembled super glue. The indicator in the dash works fine. Shows which gear it is in.
The 6.0 is out of an '05. I started it with the 5.3 tune just to see if it would and it runs fine enough to drive it to the dealership to get it re-flashed. the only problem is the pump isn't working in the tranny. I pulled to cooler lines and nothing is flowing out.

sounds like two different problems.... did you "upset" the torque converter in any way while it was disassembled? if the torque converter was not seated fully in the transmission you likely crushed the pump. The other issue sounds like you have a wire pinched some where, the wiring to the starter is very simple, so that would be a good place to start.

OK, I ended up figuring out that I had broke the pump in it. Today I pulled it out and took it to the tranny shop to get rebuilt. In hindsight I should have done this to begin with. The tranny had 145k or so on it and I was trying to be a cheap a$$ and not replace. I wish I would have since I would have my truck on the road by now. I wouldn't have put it all together just to find out I screwed up. So I wasted some time and effort trying to use the old tranny, lesson learned.
Thanks guys for all the help,
Adam
