Removes the pressed-on 5th/6th gear assembly from the mainshaft during a Tremec T56 or TR6060 six-speed teardown, including the 2013-2014 Dodge Viper.
If you have a Tremec T56 or TR6060 six-speed on the bench and the 5th or 6th gear will not come off the mainshaft, this is the puller leg the factory procedure is built around. The 9379A gear remover leg fits behind the pressed-on gear so the assembly can be drawn straight off instead of being driven with a hammer and drift. The listing covers the T56 5th gear and the TR6060 5th/6th gear assembly, including the TR6060 in the 2013-2014 Dodge Viper. It is a replacement leg, not a full puller set, so read the parts-required note below before you order.
In both six-speeds, the 5th and 6th gears sit at the rear of the gear train and are an interference fit on their shaft. They do not slide off once the retaining hardware is out; they have to be pressed. The 9379A leg hooks under the gear and works with three other pieces from the same factory tool family: the 9382 bridge spans the shaft end, the 1027 press button centers on the shaft, and the 9378 bolt kit ties the legs to the bridge. Tightening the forcing screw pulls the gear evenly along the shaft axis. None of those three pieces come with this leg. On reassembly, the gears go back on with a separate installer; Mopar's 9391A gear installer is the matching tool for pressing 5th, 6th, reverse and the 5-6 synchronizer hub back onto T56 and TR6060 shafts.
Rebuilders on Mopar forums put it bluntly: a chipped gear on one of these boxes can turn the whole transmission into scrap, because the gears are expensive and often hard to find.
You only need this leg if you are going past the shift rails and into the gear train, which is usually for worn 5th or 6th synchros, bearing noise in the upper gears, or a full overhaul. Grinding into 5th or 6th, noise that changes only in those gears, or metal on the drain plug point you inside. Our manual versus automatic transmission repair cost guide lays out what a manual rebuild typically involves before you commit to the teardown, and the T56 problems and rebuild cost guide and TR6060 problems guide cover the common failure points. If you already own the bridge, button and bolt kit and your old leg is worn or bent, this is the piece to replace.
T56 and TR6060 units were built in many versions for GM, Ford and Dodge cars, and gear diameters changed when Tremec changed ratios. If your gear is a later, larger TR6060 gear or you are unsure which unit you have, read the Tremec tag on the case and send us the tag number or the vehicle year and VIN before ordering. More tools are listed in our transmission tools section.
If the shifter is coming out anyway, it is a good time to look at the T56 short throw shifter kit for the 1993-2002 Camaro and Firebird. Challenger owners with a TR6060 can pair the job with the weighted shifter handle.

No. It is the 9379A leg only. It works with the 9382 bridge, the 1027 press button and the 9378 bolt kit, which are not included. It is meant for shops that already have those pieces or need to replace a worn leg.
It is listed for the T56 5th gear and the TR6060 5th/6th gear assembly, including the 2013-2014 Viper. Gear sizes changed between versions, so check the Tremec tag on your case and send us the number if you are unsure.
A gear installer, not this puller. Mopar's 9391A gear installer is made to press 5th, 6th and reverse gears and the 5-6 synchronizer hub back onto T56 and TR6060 shafts.
It is risky. Jaw pullers tend to grab the teeth or the synchro cone and pull at an angle, which can chip a gear or gall the shaft. The 9379A is shaped to pull from behind the gear body in line with the shaft.
Use the fluid called out for your exact transmission on its tag or in the service manual. Requirements differ between versions and vehicles, so do not assume one fluid fits every T56 or TR6060.
