Review AUSTIN HEALEY Bj8 Transmission Without fits 3000

The Austin-Healey 22-Bugatti Type BJ8 transmission is a masterpiece of automotive engineering, designed to deliver smooth, efficient power transfer in the iconic Austin-Healey 3000 models. This transmission system, specifically the BJ8 variant, was introduced in 1959 as an upgrade to the earlier BN7 transmission.

The BJ8 transmission is a four-speed synchromesh gearbox, which means all forward gears can be changed without using the clutch pedal, making it more convenient for the driver. It is a rigid unit, meaning the gearbox casing is an integral part of the car's chassis, which was a common practice during the era to improve handling and rigidity.

The gear ratios in this transmission have been carefully selected to provide the ideal balance between acceleration and top-end speed. The first gear is short for quick getaways and overtaking maneuvers, while the top gear is long for relaxed cruising at high speeds. The other gears are evenly spaced to ensure smooth progression through the powerband of the engine.

The synchromesh system in each gear ensures that engaging gears is a seamless process. When shifting gears, the cones in the gear synchros mesh together, allowing the gears to slide into place without the need for precise clutch control. This makes the driving experience more enjoyable and less demanding, especially during heavy traffic or stop-and-go situations.

The BJ8 transmission also features a lay shaft final drive, which utilizes a separate shaft for the reverse gear. This design provides better cooling for the transmission and makes it more durable, as the reverse shaft is less likely to suffer from wear and tear compared to a reverse gear located within the main gearbox.

The transmission bell housing is designed to accommodate the Jaguar XK engine, which was a popular choice for Austin-Healey 3000 upgrades. The bell housing is also drilled and fitted with a clutch release bearing, making it easy to install the clutch assembly.

The BJ8 transmission is a highly sought-after component among Austin-Healey enthusiasts and classic car collectors due to its robust design, smooth operation, and the iconic status of the Austin-Healey 3000 models. Whether you're restoring a classic car or building a high-performance hot rod, this transmission is an essential upgrade that will provide you with years of driving pleasure.
