> [@LXIFLYBY](#): > > if your banging out shifts in your car, when you get to redline and upshift the syncros actually slow down the gears and mainshaft until the collar slides in to couple it to the countershaft, because the countershaft is gear coupled to the final drive but the mainshaft and associated gears in an upshift are spinning faster than it since everything is constant mesh (this is in hondas). You can get faster shifts if you have a higher coefficient of friction in the cone area and also if you have less inertia on the mainshaft and associated equipment, like lighter clutch disks. Even though you are slowing the gear down on the countershaft, its on bearings and its coupled to the mainshaft because everything is constant mesh, and the less inertia will let the mainshaft and gears slow down faster, thus slowing down the countershaft gears so the syncronizer has less work to do even though the gears are on bearings (think of a lightweight flywheel vs regular flywheel) so in effect, the syncronizer must help slow down the mainshaft and ALL the gears in the transmission to match the gear speed to the countershaft/final drive speed. Its the opposite if your downshifting. > [@Cavi Mike](#): > > ^^^Holy fucking run-on sentence. I really hope you don’t expect anyone to read that jumbled mess. I read it and completely understood it.

The first thing I saw was a big blob of words, no capitalized first letter, ‘your’ replacing ‘you are’ and a sentence that was 4 lines long. Also ‘banging out shifts’ isn’t exactly any kind of term I’ve ever heard before, I assume he meant ‘banging gears.’ It’s just a run-on garbled mess and quite honestly I think the only reason why you guys read it is for the simple facts that: I stated no one would and you dislike me. ---

It’s one of few posts in this thread that explained how synchros function, which was indeed worth reading. ---

Havent seen it metioned yet… but whether or not the hub or gear is being driven or free depends on the design of the transmission. For example, in a W5MG1 (3000GT VR4 Transmission) the main shaft drives gear sets 1, 2, 5 and R, while hub & slider 3/4 are also driven on the main shaft. In this example, 4 gears are and 1 hub/slider is driven, not all gears or all hubs. Also, I have gear sets, main/counter shafts, hubs, sliders, single and double cone synchros laying around… if anyone wants pictures of something specific, let me know. ---

And longitudinal-engined rwd layouts don’t have a gear set for their 1:1 ratio. ---

CVT FTW Lighter, cheaper, simpler, fewer moving parts. My 2 cents.😃 PS I remember when they started using syncros in cars.😛 ---
