Which Acuity parts needed to just remove lateral slop on shifter?

[Spart]

The OEM boot is indeed designed with some forward lean to it, that's probably why you're having issues with the odd gears. If you reverse it you'll have issues with the even gears.

It seems like the taper actually goes the wrong direction. There's plenty of slack in the even gears and no slack at all in the odd ones. I wonder if flipping it around will even it out.

Ordered a gallon of this last night:

I am happy with the performance of the OEM Honda fluid in cold weather. I've also been really happy with Redline MT-90 in cold weather (in my truck) so I'm going to give MTL a shot. If I don't like it, ACDelco Synchromesh FM will be next up.

I also got the Acuity bushings to do "while I'm in there."

I am running MTL and like it a lot. In the summer I plan to swap it out to MT85 (and go back to MTL next winter). Two flushes a year might be overkill, but at least the trans won't fail from under-maintenance

I mean it's not necessarily overkill if you're tracking it.

If you aren't tracking the car, I'd probably just run one weight all year long and extend that interval.

Just fully caught up on this thread. We almost went through the same journey regarding shift upgrade! Thanks for sharing the experience. I also had the hybrid racing detent spring and didn't like it. I came across this fk8td detent spring, and a blog post about installation. It makes more sense to me in terms increasing the gear engagement feel. I can report back once they arrive and installed

I'm intrigued! Let me know how it goes if you try it!

I am also intrigued, but I will say I'm a little put off by that guy and his website.

He specifically says to not follow the Hybrid Racing instructions, but he doesn't really provide any alternative instructions for his kit?

Closest I could find is this:

...which just seems like a rant and not helpful instructions.

Also, if you browse the "DE5" section of his website, you'll see this part listed for the DE5:

https://fk8td.com/product/fk8-fl5-clutch-master-upgrade/

That is definitely not something you'd want to try installing in the DE5, as the FL5 and FK8 have completely different clutch master cylinders. What you see there is a FK8 clutch master with the integrated CMC damper. The FL5 and our cars have a different clutch master cylinder design with no integrated CMC damper. What they have instead it is a traditional clutch master cylinder and a separate (and easily removed!) CMC damper component under the battery between the CMC and the slave cylinder.

He also lists this for the DE5:

https://fk8td.com/product/fk8-fl5-clutch-slave-upgrade/

Again that is an FK8 specific part. The Honda part number for the FL5/DE5 is different. I believe the fitting for the hydraulic line is different - I haven't compared them personally so I can't 100% say for sure, but they are certainly visually different.

So that doesn't inspire confidence that his detent spring mod works the same way on the FL5/DE5 as it does on the FK8. These are really obvious generational differences that the guy is getting wrong.
