Should I be concerned about replacing fluid with Amsol voiding the warranty?
Service Tech assured that it would, but I'm experiencing sticky/crunchy shifting since delivery. They won't do anything to help as it's "operating as designed".
that's ridiculous IMO. changing fluid does not void any warranty, sounds like a crock of sh*t some dealer would push

Verbatim from Honda's highest level roaming Factory Service Technician. Worth a look into the exact warranty language it seems.

Isn’t there a difference in viscosity and weight between Honda and Amsoil MTF; that may be a reason why Honda would have a reason not to warranty? I’m about to do mine, still on the fence.

I don't think swapping out with Amsoil is going to cause any issues. That said, how would they know what trans fluid was used. I mean, are they going to do a fluid analysis in a lab if\when your tranny dies? Lots of people have used it and if you want to, go for it. There is no worry about the warranty here.

I put Amsoil synchromesh into my 2019 CTR around the 14k mile mark. I've driven with the new fluid for 3k miles and the shifting does feel better. I'm not sure if it's classic placebo effect but I was having second and third gear grinding in spirited driving that lead me to change it out. I also grinded going into reverse once while at a standstill. Since the change I haven't grinded second once and I can think of only one time getting a slight grind going into third from second.

I agree with @kimtyson too, it would be hard for Honda to prove you didn't use OE trans oil.

I wouldn't.

isn't that just the fluid inspection hole on the top? i thought the actual fill hole was on the side so oil drains out at the correct level. could have sworn there are three holes; one on top (fill hole), side (level check hole) and bottom (drain hole). if you are using a fluid pump i'd just fill it at the side level check hole. fill at top if you are using funnel.

Like you said, fill on top, level check on side, drain on bottom (with crush washer)
