![]() "The lugs on a dog-ring setup are on the face of the gears as opposed to being on the inside diameter of the slider and the outside diameter of the speed gear. A dog-ring (or face-tooth gear as it is called), is a system of gear engagement that essentially has no blocking ring, just big steel lugs (on the slider and on the speed gear) that engage and lock together to drive the transmission. If these symptoms sound familiar it may be time to call in the dogs. Ultimately, the transmission will grind all the time and may pop out of gear. When the synchro can't slow the gear down fast enough to engage the gear, the result is grinding and that shreds the teeth on the synchro. "Normally the limit is around 6,500-7,000 rpm, but a good clutch setup and a good driver may be able to go a little higher," added Long. When it comes to racing, the limiting factor with a synchronized transmission is often rpm, and that's because as rpm is increased it becomes more and more difficult for the synchronizer to slow the gear quick enough and allow the teeth to mesh. As the syncro rides up the taper it grabs the gear and slows the gear, or synchronizes the speed of the gear, so that the teeth can engage. The sliders will start to force the syncronizer onto the tapered ramp that is attached to the speed gear. "As the driver moves the shift lever he manipulates the shift forks and that moves the sliders. "A synchronizer, or blocking ring as it can also be called, is used to slow the speed gear so that the slider can engage the gear when the gears are shifted," stated Long. All factory and some race-type transmissions use synchronizers because they allow for smooth, yet quiet gear engagement. When it comes to manual transmissions there are two basic types of gear engagements, synchronized and dog-ring (also called face-tooth). In addition, there are three different ratio sets (see chart on next page) to meet the demands of drag racers, street enthusiasts and there's even a new close-ratio gear set that should be perfect for road racing. Internal upgrades include straight-cut gears and dog-ring engagement (which we'll explain later), along with a special helical/dog-ring combination that is legal for NMRA Real Street. ![]() ![]() The once race-oriented transmission manufacturer now has a huge focus on street performance and offers a T-5 with the heart of the race unit. But G-Force saw the potential of the market and took this T-5 thing a bit further. It featured a fully syncronized gear set and a 2.94:1 low gear. The first T-5 kit was developed about one year ago as a stronger-than-stock replacement. G-Force actually offers three versions of the T-5 and there are three gear ratio sets. Amazingly, G-Force's top of the line T-5 is rated up to 600 hp, while the T56 is rated to withstand 900 stomping ponies. Not only are the parts stronger, there is a variety of gear ratios to chose from and a new transmission case for the T-5. G-Force recently released a complete line of upgrades for the popular Tremec T-5 and T56 trannys. “As we grow with new divisions it is great to know that companies like G-Force will come alongside us and support that growth.In good hands, that's where.
