With today's technology and advanced ECUs, stick shift racers continue to push the envelope with more and more HP and torque. Aggressive street-style multi disk clutches can compound the issues found with keeping a transmission and drivetrain together at extreme power levels, as well - and then there is the other enemy: weight! Guys are making 1500+ whp in 'racecars' that weight 3300+ lbs!
Here at Tick, we have been campaigning our own stick shift shop car, the "Grubb Worm." The transmission you're about to learn about has been tested in our car for all of 2019 running a best of 8.01 @ 180 mph and at a race weight of 2900 lbs on a sub par surface and 90+ degree temps. The car has put down a bit over 1200whp and later turned up to what we guess to be somewhere near 1300whp without issue.
No core required, this transmission is sold complete!! If you have a core housing, shift rail components, and all other various pieces of hardware to complete this build contact someone on our sales staff at 336-719-0599.

About the Input Speed Sensor
We have found that proper clutch selection is critical to the life of your transmission as well as the rest of your drivetrain. For these extreme drag cars, this means an adjustable clutch. Having the ability to 'hit' the tire softer even with more power or RPM (and leave the line more like an automatic) will not only help keep your transmission in-tact, but it will also make the car easier to handle and much more consistent. You'll also have an advantage on days where the track surface or conditions aren't the greatest. To fully take advantage of an adjustable clutch, you need to monitor input shaft speed vs. engine speed. With the input speed sensor found in this transmission, you can monitor this data through your modern EFI system and use it to make the proper adjustments much more quickly versus trying to make changes based on sound or feel.
About the Bungs/Sprayers
The most common failure we have seen on high horsepower T56 and TR6060 transmissions is a damaged input gear and the mating gear of the countershaft. This can be an expensive repair as those are two of the most expensive parts found inside to be replaced. These gears become overheated, whether it be due to lack of fluid from hard acceleration (the fluid rushes to the rear of the trans during hard acceleration) or simply the extreme power. Being the most forward located gear in the box adds to the fluid supply issues. Also, the input gear and the mating gear of the countershaft are under load in all gears (except 4th which is 1:1 ratio) so it is easy to understand why it is the most common gear to fail. By adding bungs we provide you with a -6 AN fitting which you will plumb a fluid transfer pump into from the rear of the transmission (the original drain plug location). On the inside, there are aluminum tubes positioned to spray fluid directly in between the input gear and counter gear as well as one between third gear and the counter gear. These are positioned as such that as the transmission turns it is pulling that fluid between the gears.
About the G-Force Gear SET
The gear set found in this transmission build uses 9310 material for exceptional strength. The gears have a re-engineered design and tooth profile as well as extra gear width wherever possible. When talking about extreme power levels and drag racing stick cars, it is inevitable that you will break something inside of your transmission eventually as nothing is bullet proof. By design, the G-force gearset is much easier to disassemble (this translates to cheaper labor costs for future rebuilds.) All bearings are either slip fit or can be pressed off of their respective shaft without damage, unlike a regular T56 or TR-6060. For example, if you break an input gear, you don't have to buy a new bearing as long as the bearing is still good. The counter shaft is a two piece design as opposed to one piece on a standard T56 or TR-6060, so if you break 3rd gear for example, you only have to buy the section of counter shaft that has third and fourth on it, not the full assembly. If you bang up the face plate lugs on the input gear, it splines off the input gear/shaft so you don't have to purchase a completely new input gear (like you would have to do if you were to bang up the welded-on face plate lugs of a T56 or TR-6060.) This is a racer minded gear set!
