Update on the car.
The Bad News: 3rd Gear Grind
The shop tore into the trans and confirmed that the 2nd slider is completely shot. I had a feeling something was wrong because it was grinding at the track and popping out of gear. Before anyone asks, I’m definitely not new to manual platforms (prior cars include an RSX-S, S2K, and an STI), and I always take my time rev-matching and downshifting to protect the drivetrain.
I went to pick up the car, but it's going right back to the shop. It developed a 3rd gear grind just a few days after the dyno session. Interestingly, it didn't grind right after the initial build install, nor did it grind on the dyno itself. Right now, it looks like it could be the gear teeth or the synchros. The shop is opening it up again to find the exact failure point.
What Just Was Just Done:
• Clutch & Subframe: Dropped subframe, R&R clutch. Installed OS Giken HTR Twin Disc Clutch Kit.
• LSD & Tune: Installed OS Giken SuperLock LSD (tuned by Shaftworks). JSR Re-Tune Session.
• Trans Refresh: Honda OEM 1-2 Slider Synchro Set, S.E.S 3-4 Gear Upgrade (1000HP Synchromesh), full tear down, clean, Hondabond, and reassemble.
• Cooling & Maintenance: Spoon Thermostat, HKS Touring Coolant, NGK Ruthenium Plugs.
• Fluids: Motul 75W140 (trans) & Mobil 1 5W30 (engine).
The Path Forward (The Fix):
Instead of chasing minor fixes, I’m taking the tuner and installer's recommendation to bulletproof this thing. We are opening the case back up and installing a heavy-duty gear set.
• PPG 1-5 Gear Set
• Syncrotech 1-4 Carbon Synchro Set
• FK8 Final Drive Gear and Shaft
• Labor (Round 2)
Fingers crossed this finally cures the 3rd gear grind and locks down the transmission reliability once and for all. Will keep the thread updated once the PPG set is in and we see how it feels!
