Cb76Life is cool... so far.
Motor revs up to 5000 rpm on cold start

So I recently replaced my transmission on a f22a1. Before i replaced the transmission everything in the car was working perfectly fine. After I put the transmission in it started to act up. When I start my car up it goes straight to 4,000 rpms and then back to normal idle then revs backs up to 4,000 rpms. I have checked the Tps on the car also the Map sensor anything that had to do with the airflow on the car. The computer also isn't throwing out any codes I have no clue what cause this.

Your fitv is screwed. Replace it and bleed the coolant

Try bleeding the coolant first. It does sound like the FITV, but you might not need to replace it.
It lets in air based off of the coolant temperature, and if you have no coolant it will malfunction.
Next, follow the guides on here for fixing your FITV.
You pretty much need to open the top of it (via phillips head screws) and turn the white
piece of plastic down all the way, then back it off 1/4 of a turn.

There's lots of other things it could be. There is an extensive DIY on here written by HondaFan. Look up that too.

Revving up to 5k sounds like you should look for a vacuum leak.... May have forgotten a vacuum hose or maybe cracked one while doing the swap.

Aside from the TPS & MAP there is also the intake air control (IAC), Fast idle thermal (FIT) and Air boost (AB) valves that also have to do with air flow. Any one of these three could be leaking, out of adjustment or just not working.

I'm willing to bet you over tightened the kick down cable and its holding the throttle open slightly.

Do you have a vacuum gauge? Also try a little brake cleaner around the engine bay and listen for idle changes before you go spending money

Did you try spraying anything to find a leak? Sometimes they are really faint and you cant hear them unless you use something like starting fluid to change the idle and find them.
