Toyota Gearboxes
This page contains a list of Toyota gearboxes used in Lotus cars.
ZZ-series Gearboxes
Gearboxes used in cars equipped with ZZ-series engines, such as the 111R, Toyota engined "Elise S", S2 Exiges and the 2-Eleven.
C64
Fitted in all the 2ZZ-GE engined Lotus cars including the Elise 111R, Elise SC, all S2 Exige variants and the 2-11 (GT4 excluded). The C64 is a six speed transmission and features the following ratios.
| 1st | 2nd | 3rd | 4th | 5th | 6th | Reverse | Final |
|---|---|---|---|---|---|---|---|
| 3.166 | 2.050 | 1.481 | 1.166 | 0.916 | 0.815 | 3.250 | 4.529 |
Other C6x gearboxes, such as the C60 and C63, are used in conjunction with the ZZ-series engine in cars such as the Toyota Celica. The C60 features identical 1st-5th ratios and final drive, but with a longer 6th gear, while the C63 features a completely different gearset (other than 1st) and longer final drive, reducing acceleration but increasing in gear speeds.
| Varient | 1st | 2nd | 3rd | 4th | 5th | 6th | Reverse | Final |
|---|---|---|---|---|---|---|---|---|
| C60 | 3.166 | 2.050 | 1.481 | 1.166 | 0.916 | 0.725 | 3.250 | 4.529 |
| C63 | 3.166 | 1.904 | 1.310 | 1.031 | 0.864 | 0.725 | 3.941 |
Known Issues
There have been reports of a weakness in the syncro-mesh in the C64 gearbox on 3rd and 4th gear. Changing the gearbox oil and engine mounts has been observed in some cases to cure or lessen this issue: http://forums.seloc.org/viewthread.php?tid=311604
In the event of a gearbox failure (or if increasing power or planning on using the car heavily on track) then it is highly worth considering the stronger Jubu Racing Gearset for a rebuild, along with an gearbox oil cooler to reduce gearbox temperatures.
C56
Fitted by Lotus to the Elise S (2007-2010) with the 1ZZ-FE engine, the Toyota C56 gearbox is a 5-speed transmission.
Gear ratios for this transmission.
