Production 6-speed manual transmission from Cadillac ATS
The high torque capacity of the TREMEC TR-3160 six-speed manual transmission is perfectly suited for light delivery vans, light commercial vehicles and pick-up trucks, as well as high-performance vehicles. The fully synchronized transmission with single overdrive allows the vehicle to cruise at sustained speed with reduced engine RPM — leading to better fuel economy, lower noise and lower wear. Refinement is the hallmark of the TR-3160, as shift quality and noise levels are exceptional to support performance. The shifting experience is swift, precise, quiet and effortless, thanks to shift quality-related features:
•High-precision guide plate
•Advanced interlock system
•Anti-friction roller ball detents
•Individual shift rail for each speed or Multi-Rail Shifter
•Light weight transmission; lighter aluminum castings, hollow shafts and webbed gears
•All gears synchronized
•Low-friction linear shift rail bearings
Additional features include the use of low-friction Dexron VI lubricant, low-friction and high capacity tapered bearings, as well as large, high-capacity synchronizers that contribute to low shift efforts and shifter travel. All of the gears are hard-finished, which contributes to transmission’s refined feel and low noise. The case of the TR-3160 is made of lightweight aluminum, which contributes to low curb weight.
Double- and Triple-Cone Synchronizers Design features of the TR-3160 include a combination of double and triple cone hybrid and sintered bronze synchronizers on all gears. Synchronizers act like clutches to speed up or slow down a gear that is being shifted. Double-cone synchronizers have two friction surfaces to effect this gear acceleration, and triple-cone synchronizers have three friction surfaces. The greater the friction surface, the easier the transmission is to shift.
Internal Multi-Rail Shift System
The TR-3160’s internal multi-rail shift system places the shifter directly on the transmission, enabling very short, precise and positive-feeling gear changes. There are no cables connecting the shifter to the transmission, which could cause a “rubbery,” less-precise feel.
Light and Compact Design
The compact aluminum housing, hollow shaft technology and optimized gear thickness reduces weight of the vehicle and increases the payload. The TR-3160 provides a small package design with high-torque capacity
