Manual Transmission Description and Operation (M3L)
WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
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: M3L 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, REVERSE
- An internal shift rail mechanism
- A remote transmission shift control mounted forward of the transmission
- An external transmission shift rod enabling the rearward mount location of the transmission shift control
- Tapered roller bearings supporting the mainshaft and countershaft
- Caged roller bearings under all speed gears
These features combine to yield a rugged, reliable system capable of handling input torques of 400 N.m (295 lb ft) for RPO: M3L.
The gear ratios are as follows:
| Gear | M3L Ratio (:1) |
|---|---|
| FIRST | 4.12 |
| SECOND | 2.62 |
| THIRD | 1.81 |
| FOURTH | 1.30 |
| FIFTH | 1.00 |
