Jaguar 5-Speed Manual Transmission Conversion

There's something uniquely satisfying about shifting through the gears in a classic Jaguar. It's part of the connection between driver and machine. Yet, decades of wear, aging components, and 1960s transmission technology can make that experience feel less rewarding than it once did.

The original gearbox was engineered for a different era. Without a modern overdrive gear, highway driving often means higher RPM, more noise, and additional wear on the engine during longer journeys.

A Tremec 5-speed conversion restores confidence behind the wheel while preserving the character that makes driving a classic Jaguar so special. For owners converting from an automatic, adding a third pedal creates a far more connected, engaging driving experience while often increasing the vehicle's appeal and long-term value.

• Race-proven Tremec 5-speed transmission
• Gear ratios matched to classic Jaguar production driving characteristics
• Approximately 30% lower RPM at cruising speed
• Modern synchronizers, bearings, seals, and internal materials
• Strong maintenance and parts support infrastructure
• Elevate your E-type's driving experience

A 5-speed conversion delivers benefits that go far beyond adding an extra gear.

Effortless, confident shifting

Increased value while maintaining pedigree

A properly installed Tremec 5-speed conversion enhances everything enthusiasts love about driving a classic Jaguar, delivering greater driver engagement, improved touring comfort, and lasting value without compromising the character that makes the car special.

A Jaguar 5-speed conversion is not a simple bolt-on job. The engine, exhaust system, fuel system, transmission, and driveshaft may all need to be removed, inspected, prepared, and reinstalled correctly.

It's Alive Automotive is a certified installer of the Driven Man 5-speed conversion kit. We have installed countless units and understand the details that determine whether the finished car feels right.

Our process includes confirming the correct clutch disc, flywheel, ring gear, starter engagement, driveshaft fitment, and installation sequence before everything goes back together. We also look for related services that are best addressed while the engine and transmission are already out of the car.

The result is a cleaner installation, fewer surprises, and a better finished driving experience.
