Do yourself a favor and nut up for some Honda MTF fluid. I've found that Honda transmission's shift better when you use Honda MTF.

As a corollary, I have 2005 Chevy Colorado with a 5 speed manual. When I bought it, it had some generic gear oil in it. It didn't shift very well. The syncros were very stiff and required a lot of force to move between gears. About a year ago I drained that stuff out and re-filled the transmission with the specific fluid that GM specified. It was not cheap, something like $18 a quart and if memory serves, I needed 2.5 quarts.

What a world of difference. The transmission went from being clunky and hard to shift, to a smooth shifting beauty.

The Honda MTF is $14 a quart (on Amazon) and you only need two of them.

Couple weeks and I'll report on the difference between the two.

This stuff was $30 of my last $50 between paychecks.

Probably not a horrible idea to run some new stuff for a short time just to knock out the warehouse crud/cobwebs and give her another 1.6qt of fresh honda stuff after a few miles, yeah?

Oh heres (maybe) a better attempt at explaining my horrible grind.

Hmm... https://photos.app.goo.gl/xE3fvX3BbDQmhTkJ6 ... the "img /img" html doesnt look like it likes that so heres just the url. ~~/EDIT~~

Saw the picture of the shafts showing the difference.
That link worked.

Are you following the procedure for reinstalling the engine/trans mounts? Also all the 1G mounts should work well with the HCH trans. Same with the shifter cable bracket.

Looks ok to me, as long as you didn't wear into the surface that comes in contact with the pilot bearing should be fine.

Oky doky so its all together and drives like an entirely different car.
Well not quite. The suspension is still atrocious but she has a normal (perhaps slightly more) small Honda amount of pep.
She seems to like those wide open throttle moments.

Oh theres a procedure for the mounts? heh heh oops. I mean its in and working...
I guess I have more than 1 cleanup task to do tomorrow then.
OH NO! I see now, over in BullDogs post.
Those stud bulges could split the mount the way I have it.
Hmm. I bet youre right. Thats why the rear didnt want to line up. :/ yeesh.

As far as the input shaft, I did stay well away from the bevel at the very tip. Thank you for the reassurance. ALSO... Heres that original gearbox.
(just in case)
(just in case)

:OFF TOPIC:
03 Intrepid front struts look FAIRLY similar to ours. If that jeep "solution" has a matching top mount we might be in business.
:/Off Topic/:

The other item on the cleanup list is, this morning I thought I got the driver side brake shield touching my rotor but on my way home I was on a 30 mph right-hand bend & I heard and felt (in the whole car. not just the wheel or just the pedal) sort of a "thump thump thump thump thump". What does a bad inner CV joint sound like? I had the driver side one overextended three times now and have only ever experienced the outer joints going bad. (93 Integra, 84 CRX, 91 Civic, probably more)

So nothing wrong with my 2000 insight trans with 220k on it, but...... secong gear little notchy. I hate 1st gear but that was gas only no ima. With ima working its not as bad. But jump from first to second always requires assist.
Just seing if hch trans swap is worth it for an insight with a lto conversion, current hack, mimac&c , and a turbo.

Does hch trans have better synchros or better design than the insight? Reading through posts on both trans swaps and gears from fit. Can the countershaft and ring gear from hch be put in the insight trans. Making use of the lighter case, hollow shift shafts.

More than likely it's the mount shifting causing excessive vibrations to be transmitted to the chassis. I had something similar and thought it was my CV axle, but it was the mounts shifting around.

I would say with a turbo absolutely. You aren't going to be making great boost at 3k rpms which is right around where you fall when you go from deep into the redline in first into second. You'll be quite a bit higher and you'll build way better boost.

The only thing I would say is with the LTO and turbo combined you might want to have the final drive be the Insight if that's possible to keep you in lean burn at higher speeds while you're giving the car continuous small amounts of assist. VTEC will screw with things way earlier if you have the HCH final drive. The 2-3 shift is also way better. For legal driving speeds and shifting at redline the 1-2-3 are way better matched for getting up to speed especially on a 75 or 85mph freeway.
