2-3 Shift Flare 93 300CE

[jlostlen]

Ive got a flare when shifting from 2nd to 3rd in my transmission. The 3rd gear catches into gear for a millesecond, slips out of gear, revs up, and then i feel it catch again and then the tachometer goes back down.
I get this issue if I manually shift from 2nd to 3rd as well, so i know that does rule out some culprits.
No other gears have this issue and shift pretty well. I have a code 26 for a upshift delay, which im told will not affect this condition. I reset the code and the code has yet to come back up for a day.
The flare is more severe at higher acceleration and still noticeable at slow acceleration

Thanks for reading,
