Frequently Asked Questions
Got questions about TREMEC® transmission swaps, overdrive conversions, or drivetrain fitment? Here are answers to the most common things we’re asked before a project begins.
Will this require cutting or modifying my transmission tunnel?
In most cases, minimal to no tunnel modification is required. Modern TREMEC® transmissions like the TKX are specifically designed for retrofit applications and fit many classic chassis with clean, factory-style clearance. Any necessary modifications are kept discreet and structurally sound.
Which TREMEC® transmission is best for my build?
That depends on your engine output, vehicle weight, driving style, and gearing goals. We help you choose between options like the TKX or T-56 Magnum based on real-world use—not just horsepower numbers—so the transmission matches how you actually drive the car.
Can you keep the factory shifter location and interior looking original?
Yes. Shifter placement and interior appearance are carefully planned during every swap. Whenever possible, we retain factory shifter locations and interior aesthetics, or make subtle adjustments that look period-correct and intentional.
Is an overdrive conversion worth it for highway driving?
Absolutely. Overdrive dramatically reduces highway RPM, engine noise, and wear while improving fuel efficiency. It transforms long drives from tiring to effortless—one of the biggest drivability upgrades you can make to a classic car.
Do you supply clutches, hydraulics, and driveshafts as part of the swap?
Yes. We offer complete drivetrain solutions, including custom driveshafts, matched clutch systems, hydraulic throw-out bearings, and proper alignment. Everything is selected to work together for smooth engagement and long-term reliability.
