The Classic Jaguar 5 Speed (CJ5)tm
Patent Pending

As the world leader in performance and reliability upgrades for the E Type Jaguar, it should come as no surprise that Classic Jaguar is also the home of the ultimate E Type and XK five speed conversion - the CJ5.
Picture yourself cruising the highways and byeways at 70 mph turning barely 2,000 rpm. Long distance adventures become far more enjoyable with the relaxed performance and economy of a CJ5 five speed!
All CJ5 five speeds are bench tested 
at high pressure prior to delivery
The CJ5 - designed and built
by Classic Jaguar
When we set about designing and manufacturing our CJ5 five speed we set ourselves some ambitious goals. We sent our engineers back to their drawing boards with a clean sheet of paper and told them that our only fixed paramaters were the dimensional characteristics of the various OEM Jaguar four speeds and the fact that we wanted to use the excellent, smooth shifting World Class (WC) Tremec T5 as the base platform.
E Type CJ5 ratios
1  /  2.95
2  /  1.94
3  /  1.34
4  /  1.00
5  /  0.73
0.80 fifth gear ratio also available
The CJ5 is not a modified WC T5. Every component is brand new, from the main shaft to the tailhousing. CJ5 mainshafts, input shafts and all other critical components are made in ISO 9000 certified facilites. Please also note that the CJ5 uses a stock (OEM) Jaguar clutch pressure plate, clutch disc and throw-out bearing (including the V12 model), clutch slave cylinder (including the V12 model) and crankshaft pilot bushing.
CJ5 generally in stock for
immediate delivery!
Input shaft is new - not modified - and is designed 
to be used with OEM Jaguar clutch
The CJ5 for SWB 6 cyl E Types is precisely the same length as your old 4 speed transmission, so there is no need for you to fabricate or modify your own driveshaft as our competitors would have you do. Owners of V12 E Types and the various XK models will receive a brand new driveshaft as part of their CJ5 kit.

Customer comment!

The CJ5 five speed is ABSOLUTELY SUPERB! It transformed my XK 150S from a frumpy, whining, 1950's vintage sports car into a smooth, modern highway machine that daudles along at 80 at about 2900 rpm. It is a fabulous upgrade - thank you!
