shifting problems
Hi,
Hoping if anyone could shed some light on my issue with shifting. Own a 2002 ap1 and recently installed a carbonetics single carbon clutch.
In low revs car shifts like butter throughout all gears however after VTEC engagement or nearing 9k rev when shifting from 1st to 2nd gear I have problems engaging the shift lever to this gear after clutching in, similarly when shifting to third and also fourth at the same high revs after VTEC engagement. I have to wait a bit longer only then I am able to engage the gear.
I'm trying to diagnose where the issue could be, is it my synchros are going? Is it due to clutch pedal not operating efficient when I clutch in to change gear quickly? Does the clutch oil have an air bubble and needs to be redone?
Any other suggestions would be appreciated. Thx.

I would bleed the clutch line, it could have air bubbles in it, make sure you have fresh clean fluid in the clutch master cylinder and it is clean of all deposits.
Check the clutch rod freeplay, it may need adjustment, if it has too much freeplay it can affect the clutch disengagement.
How old is the tranny fluid ?, what fluid are you running in the tranny ?

Thx for the reply and suggesion. Im using redline mtl. It was change abt 4 months ago but I havent used th car much due to being overseas. But prior to going overseas i did a few spirited runs and noticed 2nd and 3rd grind slighly and hard to engage when shifting at high rpm.
Thx

start with changing the fluid in the clutch master cylinder and bleed the clutch...then id look into re-greasing the shifter...between those two things and relatively new-ish tranny fluid, it should feel 100 times better

My car had Redline MTL in the tranny when I bought it, I had an issue with 1st-2nd gear slightly grinding. Changing to Honda MTF2 made an immediate difference. I followed up with a re-grease of shifter, clutch rod freeplay adjustment, clutch fluid mc cleaning and fluid swap. My tranny runs like it is brand new now in really cold or hot conditions, so I'm hesitant to try other fluids. I run a heavier shift knob but that's just for improved feel.
I'm willing to bet Honda MTF2, Amsoil MTF, or GM Synchromesh Friction Modified will work better than the Redline MTL. Bleeding the clutch fluid line might be worth a try if the line was opened up in the past.

I'm having the same issues and was wondering what ended up fixing the issue, if a solution was in fact discovered.
I have an SOS Sport Clutch and just recently started noticing the same happening in pretty much all gears. It all started with only 4th gear giving an issue, but not all.
Thanks.
