2-3 Shift Flare 4r44e
So, I bought a 00 Mazda B3000 (Ford Ranger) two months ago, and it has begun to flare between 2-3 gears. It didn't do it immediately when I bought it, but over the 1k miles I have driven it this issue has appeared (not really sure when). Right now it is sitting at 131k. I did a 3.5 qt fluid change right after buying it.
It downshifts into third fine, and if I let off the gas right before the 2-3 shift, it shifts fine as well. The only time it does the flare is when I am accelerating decently and I am at operating temperature.
The rest of the gears shift fine, although they are a little weak so I suspect the previous owner did some hauling that wore the clutches or something. I might have to replace this tranny at some point anyway, I would still like it to last as long as possible but this shift flare is kinda getting annoying.
From my research online, it can be a number of things, such as:
A problem with the intermediate servo, servo spring, or servo bore (that last one requires a whole new tranny right?).
A problem with the EPC solonoid
A problem with the valve body gasket
I also saw a thread that recommended putting a shift kit in as well. I found one on rockauto for about 50 bucks so I might give that a try.
Overall I can replace all of the parts listed above for around 150, but I would like some advice on which to do first, or if I should even do them at all. I am a little bit of a noobie to transmissions (and automotive work in general), so any help is appreciated. If I do all of these fixes and it is still doing it I am going to throw some lucas stop slip in there and ride it till it dies
Thank you!

In case anyone was wondering, I did fix this issue
I replaced the valve body gaskets, EPC solonoid, and installed a trans-go shift kit. It shifts great now.
The gasket was actually a bonded gasket, but it still looked like it was coming apart. I sanded off the gasket and put new ones on, that was about the hardest part.
