Confused on Trans issue...

[bmos37]

Anyone have any thoughts on what could i be doing wrong here?

I recently (today) switched my Trans in my truck out for a suncoast stage 5 built Trans that also has the 6 speed valve body & TCM, I was under the impression that it was going to be a plug & go installation ( suncoast site says 1 hour install) well now I am getting the P0700 & P 0708 codes & truck does not display the pointer for which gear it is in. & will not shift gears ( I have reverse & drive) but no shifting.My question is what am I doing wrong? I have efi & of course @ the moment my computer is down so I can't do anything there ( not that I would know anyway's) the TCM has the same build #'s as the original in the truck.The ECM is the ECM that I would eventually like to use also
Any info would help here.

NSBU Neutral Switch Back Up switch. There is a procedure for adjustment. I have not had to do it but others here have.

Need more info on exactly what you changed. Was the NSBU switched? If so, did you just throw it it on without paying attension to how it was indexed?

Mike,
I changed nothing on the Trans, I pulled it out of one truck & put it in mine. I used everything from the donor truck in mine. That is where the confusion is.

Got it all figured out!
It was the NSBU switch didn't realize it was rigged in the donor truck.

Thanks to those who put me on the path.
