Manual transmissions are identified by the number of forward gears and the measured distance between the centerline of the output shaft and the counter gear.
The 6-speed manual transmission (RPO M10), used in SSR, incorporates the following features:
• | An aluminum case |
• | Fully synchronized gearing with an enhanced synchronizer cone arrangement: |
- | Triple-cone: FIRST, SECOND |
- | Double-cone: THIRD, FOURTH, FIFTH, SIXTH |
- | Single-cone: REVERSE |
• | An internal shift rail mechanism |
• | Tapered roller bearings supporting the mainshaft and countershaft |
• | Caged roller bearings under all speed gears |
• | Solenoid inhibit of REVERSE gear during predefined forward motion |
These features combine to yield a rugged, reliable system capable of handling input torques of up to 542 N·m (400 lb ft) for the M10.
The gear ratios are as follows:
Gear | M10 Ratio (:1) |
---|---|
FIRST | 3.01 |
SECOND | 2.07 |
THIRD | 1.43 |
FOURTH | 1.00 |
FIFTH | 0.84 |
SIXTH | 0.57 |
REVERSE | 2.90 |
A reverse lockout system, consisting of a reverse lockout solenoid which operates a reverse lockout mechanism, is utilized to prevent shifting into REVERSE gear when the vehicle is moving forward at a speed of 5 km/h (3 mph) or more.
