Exhaust Manifold
The exhaust manifolds have a double wall
construction and are manufactured from
austenitic stainless steel. The double wall
construction has a number of advantages:
¥ it provides a significant reduction in the
external heat generated and therefore
improves underhood thermal management
¥ a heat shield is not required
¥ the durability of the manifold is increased (eg
less likely to crack)
¥ by retaining heat, the insulation effect
provides a slight improvement in the time to
catalyst light-off.
The manifold couples to the catalytic converter
via a spherical joint which requires no gasket or
sealant. EXHAUST MANIFOLD

Introduction
Manual Transmission AJ-V6/AJ28
64In Europeon markets only, manual transmission is fitted as standard on the V6 entry S-TYPE model and
as an option on the V6 high specification model. Manual transmission is not available for the V8 variant.
The manual transmission is a 5 speed Getrag 221 unit with the following features:
¥ direct gearing (1:1) on 5th gear (it is normally on 4th) reduces losses
¥ twin synchronising cones on 1st and 2nd gears provide a smoother change
¥ four plane shift gate (R-1-3-5) with Ôknock-overÕ protection on the Reverse position.
A reverse light switch and speed sensor are fitted on the LH side of the gearbox. The speed sensor
monitors output shaft speed to provide an input to the PCM in addition to the signals received from the
road wheel speed sensors.
