I only have first and reverse

I had the automatic transmission rebuilt for my 2004 after the install was complete I took it for a little test drive and found it would not shift out of first. I have checked and cleaned all connections the fluid level is perfect. Does anyone know if the tcm possibly needs flashed. Looking for some more possibilities. Thank you in advance.

Don't know what's wrong, but I think I would be revisiting the shop that did the rebuild.

You don't check anything. Right back to the shop.

Did you pull it, have them rebuild and you reinstalled?

Are you sure you are not getting 2nd gear & reverse? That would be “limp mode” & usually happens when you get a check engine light & a transmission trouble code. Even if the light is not on check for codes by turning the key without starting it on-off-on-off-on and reading codes in the odometer display. If there are no codes it will say “done”. If you have any trans codes that should help the shop that rebuilt it identify the problem when you take it back to them. Or you might drive it to them if it is not too far away so they can drive it & check it for themselves.

P0700 is a generic trans code. With a reader that reads trans specific codes which a trans shop should have it will probable show 1 or more other codes.

Why haven't you already taken it back to the shop that rebuilt the transmission? They obviously screwed something up in the rebuild, they should have noticed that issue during the test drive. I wouldn't tell them you did anything, I'd just drive it in there and tell them to fix their problem and don't call you to come pick it up again until it's perfect.

There was no test drive on their part. I did the remove and replace their only responsibility was the actual rebuild.

They should be away the shop could of bench test it before they called you. I'm not for certain about that, but Im thinking there is a way.

With out a tranny dyno no way to really test the hydraulics or electronics out of the vehicle. The only people I know that have that kind of equipment is like TCI or a major manufacturer. At least that I'm aware of.

What problem did you have before your transmission was rebuilt?
Just curious. Mine went into limp mode a couple years ago with no warning.
Mine turned out to be a bad TCM. More details by clicking the link below.

The seal for the selector shaft went bad and let water get down in it. In turn it froze it in place. I had it fully rebuilt because it was out and had 140k hard miles on it.

You don't have too many options other than pulling the specific code, and/or getting it to the shop that did the rebuild and let them diagnose it. It could be a bad TCM since it is in limp mode. I would not toss parts at it on a hunch though.
