Weird tachometer bounce..
2002 TL Type S auto... Typical tranny hard shifts but drives normal and only acts up once in a while.... Looking into a AV6 swap.
My issue now is every time the car shifts gear and reaches the rpm to match the gear then returning to it normal state there are like 2 rpm bounces then it settles... It also happens when I'm coming to a stop.. I'm in two minds if its throttle related or my gauge is going bad.
NO CEL for that issue... Idles normal at 750 when warm.. Coil pack #2 was changed last year with random misfire codes but drove normal after
Any body knows what this could be...

Okay.. I accept that answer . But if I'm cruising 45 mph and it bounces if I brake briefly still could be tranny? I only ask because it's similar to my civic that had bad IACV but I don't have erractic idle on this.
I know these trannies highly vulnerable... There's just the slightest of times especially if its very hot I will get that stuck in neutral thing ... Thankfully I don't drive it on highways and I can pull off on the shoulder and start again... I'm saving up for the swap or a different vehicle so I hope I can bide on time.
One thing that concerns me is my mom took it for a transmission fluid change at Jiffy Lube in 2016... I have no clue what brand or type fluid they used. She said they told her they used an equivalent.. 'm guessing Dexron. Because I didn't thing much of it till recently. I bought HONDA genuine DW-1 but scared it may make issues worse if I change it.

If you really think they didn't use Honda fluid immediately go out and buy 9 qts of Honda tranny fluid.
Do the 3x3 drain to try to get all the Dexron fluid out. Hopefully it's not too late.

IMO: Ditto on NSXNEXT's suggestion. Per the Owners manual, " Dexron lll is usable, as a temporary alternative to Honda Z1 ", but should be exchanged with Honda fluid " as soon as convenient", as Dexron may impact shift quality!
