I just changed my throttle body as well just a shot in the dark to see if the sensors were bad or something. I was running into the same question as you. That IAC valve has a different number for the last number. I wouldn't worry about it too much.
I got a used one off ebay, and I was checking the number on all of them. I did eventually find one that ended in a 0, but it was very hard to find. There was probably like 3 of them out of hundreds. I saw a lot of them that ended in 1, but I really don't think it matters. My car is an 01, and the throttle body came from an 03. Pretty sure they're pretty much interchangeable, especially if only the last number is different.
I've replaced my transmission 3 times already, so I've been through the slipping before. I've tried a lot of the transmission additives. Lucas stop slip actually killed my first transmission. Maybe I overfilled it or something, but it was completely done after I put that stuff in there. I did try again afterwards and it helped a little bit.
The weak spot of the transmission between 2nd and 3rd gear. Mine started flaring a few years back.
The thing that worked best for me was a fresh 3 quart drain and fill of Honda DW1 with 4oz of Lubegard red. It would actually make the car run pretty good for a couple of weeks. My friend has a GMC Yukon Denali, and he even put some in his transmission and it got rid of his transmission rumble even though it was the wrong type. I think domestics are suppose to use Lubegard platinum or something. Red is for Hondas.
But yeah, give that a try. Should be like 30 bucks for 3 quarts of ATF, and like $10 for the Lubegard red. It's $8.39 on ebay right now: Lubegard Red Ebay . I've bought from that seller before and he's fast.
I've also tried Seafoam Transmission treatment. I don't think it did anything. The one I disliked the most was Rislone Transmission Stop Slip. It made the car feel really heavy and the shifts were really lazy. It felt like it took forever to shift.
