Isolated grinding almost always means an isolated problem.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDownshifts are worse than upshifts.\u003c\/strong\u003e The useful one. On an upshift, revs are falling naturally and the synchro gets help. On a downshift it has to drag the clutch disc and input shaft up to speed by itself. If the car upshifts quietly but grinds or refuses on a normal downshift, your synchros are worn.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIt's getting worse.\u003c\/strong\u003e Wear starts as slight notchiness and progresses to metal-on-metal grinding you feel in your hand.\u003c\/p\u003e\n\n\u003cp\u003eOne honest note: grinding can also come from a clutch that isn't fully disengaging or from low or wrong transmission fluid. Rule those out first, they're far cheaper than pulling a transmission.\u003c\/p\u003e\n\n\u003ch4\u003eAccord Owners: Measure Your 3-4 Fork\u003c\/h4\u003e\n\n\u003cp\u003eThis is the most important section on the page, so don't skip it.\u003c\/p\u003e\n\n\u003cp\u003eThe two Accord kits are separated by \u003cstrong\u003e3-4 shift fork thickness\u003c\/strong\u003e, not by transmission code. That matters because six transmission codes (P2A5, P2U5, M2L5, M2S4, M2J4, and M2J5) appear on both kits. Reading the code off your case will not tell you which one you need.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e6.5mm fork\u003c\/strong\u003e takes SYN115-3A, the 1992-1995 kit.\u003cbr\u003e\n\u003cstrong\u003e7.5mm fork\u003c\/strong\u003e takes SYN115-3, the 1996-2002 kit.\u003c\/p\u003e\n\n\u003cp\u003eThey're not interchangeable. A 6.5mm fork car will not accept the 7.5mm kit and vice versa. Measure it rather than guessing from the year, especially on a car that's been swapped or rebuilt over the last thirty years.\u003c\/p\u003e\n\n\u003ch4\u003eAnd Check Your Second Gear Synchro Design\u003c\/h4\u003e\n\n\u003cp\u003eOne more thing while you're in there, and this one catches people.\u003c\/p\u003e\n\n\u003cp\u003eBoth Accord kits are built for a \u003cstrong\u003e3-piece dual cone second gear synchro\u003c\/strong\u003e. Some early models came with a \u003cstrong\u003esingle piece\u003c\/strong\u003e second synchro instead, and those won't work with either kit.\u003c\/p\u003e\n\n\u003cp\u003eSo verify your second synchro design before ordering. If you're not certain what you're looking at, get in touch and we'll help you identify it. Better a phone call now than the wrong parts with the transmission already apart.\u003c\/p\u003e\n\n\u003ch4\u003eCarbon Or Brass?\u003c\/h4\u003e\n\n\u003cp\u003eBoth fix a grinding transmission. They suit different cars.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrass\u003c\/strong\u003e is the OEM-style material and the right pick for most street cars. It restores factory shift feel, it's proven over decades, and it costs less. Refreshing a daily driver or a mostly stock car, start here.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCarbon\u003c\/strong\u003e is Synchrotech's Pro Series, using a full carbon composite lining built on carbon-carbon technology originally developed for aerospace. The material acts as a braking element during engagement, stopping the gear faster, which means less grind on high-rpm shifts and less wear on your sleeves and engagement teeth. If you shift hard, run track days, or have built the engine, this is the one.\u003c\/p\u003e\n\n\u003cp\u003eStraight talk: carbon shifts better, but don't expect dramatically longer life than brass. You're paying for how it engages.\u003c\/p\u003e\n\n\u003ch4\u003eCheck Your Hubs Before You Order\u003c\/h4\u003e\n\n\u003cp\u003eSynchros work against your hubs and sleeves, and if those surfaces are worn, new synchros of any material won't fix your shifting. New carbon on a chewed-up hub is no better than new brass on one.\u003c\/p\u003e\n\n\u003cp\u003eThis kit includes new slider sleeves, so half of that equation is handled. But inspect your hubs and your engagement teeth before you close it up. Sharp and clean means this kit transforms the shift. Rounded off means you need hubs too, and finding out now is far better than after everything's back together.\u003c\/p\u003e\n\n\u003ch4\u003eWhat's In The Kit\u003c\/h4\u003e\n\n\u003cul\u003e\n    \u003cli\u003e1-5 synchros (carbon or brass, your choice)\u003c\/li\u003e\n    \u003cli\u003e1-5 synchro springs\u003c\/li\u003e\n    \u003cli\u003eBrass reverse synchro and spring\u003c\/li\u003e\n    \u003cli\u003e1-5 slider sleeves\u003c\/li\u003e\n    \u003cli\u003e5 shaft bearings\u003c\/li\u003e\n    \u003cli\u003e2 axle seals\u003c\/li\u003e\n    \u003cli\u003eInput seal\u003c\/li\u003e\n    \u003cli\u003eShift rod seal\u003c\/li\u003e\n    \u003cli\u003eNew dust boot\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThat's a genuinely complete rebuild, including the seals and dust boot most kits leave you to source separately.\u003c\/p\u003e\n\n\u003ch4\u003eFind Your Kit\u003c\/h4\u003e\n\n\u003ctable\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth scope=\"col\"\u003eApplication\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eTransmission Codes\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eCarbon\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eBrass\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1993-2001 Honda Prelude\u003c\/td\u003e\n            \u003ctd\u003eM2Y4, M2A4, M2F4, M2B4, T2T4\u003c\/td\u003e\n            \u003ctd\u003eSYN109\u003c\/td\u003e\n            \u003ctd\u003eSYN109B\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1998-2001 Honda Accord Euro R (JDM \/ EUDM)\u003c\/td\u003e\n            \u003ctd\u003eU2Q7, T2W4\u003c\/td\u003e\n            \u003ctd\u003eSYN109E\u003c\/td\u003e\n            \u003ctd\u003eSYN109EB\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1992-1995 Honda Accord, 6.5mm fork\u003c\/td\u003e\n            \u003ctd\u003eH2A5, H2U5, P2A5, P2U5, M2L5, M2S4, M2J4, M2J5\u003c\/td\u003e\n            \u003ctd\u003eSYN115-3A\u003c\/td\u003e\n            \u003ctd\u003eSYN115-3AB\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e1996-2002 Honda Accord, 7.5mm fork\u003c\/td\u003e\n            \u003ctd\u003eP2A5, P2U5, P2A8, M2L5, M2S4, M2J4, M2J5\u003c\/td\u003e\n            \u003ctd\u003eSYN115-3\u003c\/td\u003e\n            \u003ctd\u003eSYN115-3B\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eBoth Accord kits require a 3-piece dual cone second gear synchro.\u003c\/p\u003e\n\n\u003ch4\u003eWorth Doing Once\u003c\/h4\u003e\n\n\u003cp\u003eGetting into the transmission is the expensive part of this job, whether you're paying a shop or spending your own weekend.
