Repairing the 1988-1994 XJ6 Transmission
The entire mechanical 4HP 22 transmission fitted to 2.9, 3.2 and 3.6-litre Jaguars is just about bullet proof, and with regular servicing should last the life of the car. The 4HP 24 E9 dual mode gearbox fitted to 4-litre cars is still very excellent, but can suffer from the odd electrical glitch and these are well off to be left to a specialist to sort out. The GM 4L 80E gearbox fitted to the V12s is basically an updated Turbo 400 with an overdrive fourth gear; they are commonly reliable but can develop a whine in first and reverse gears, which although slightly annoying is not normally a warning of impending failure.
Manual cars were fitted with, in turn, GETRAG 265 (separate bell-housing) and 290 (integral bell-housing) type five-speed transmissions, which, although very long lasting, have virtually no parts backup so it is a good idea to note which is fitted and keep a spare box handy. The hydraulic clutch should ideally be flushed with fresh fluid every two years and rebuilt every six.
