This page contains a list of Toyota gearboxes used in Lotus cars. Gearboxes are listed chronologically, in order of introduction in to the Lotus line-up.
Elise Gearboxes
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 syncromesh 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
C56
Fitted by Lotus to the Elise S (2007-2010) with the 1ZZ-FE engine, the Toyota C56 gearbox is a 5-speed transmission.

EC60A
Rumored to be the hydraulically automated version of the EC60 found in the Elise SPS, you can find more information here: SELOC - Speculating on the Elise SPS
This gearbox is found in the Toyota Auris 1.6 Multimode, and it's gear ratios match those of the standard EC60.
Evora Gearboxes
For more information on the Evora gearbox options be sure to look at the Wiki entry Gear Ratios - Evora, which contains extensive information on the Evora gearbox options.
EA60
Originally source designed for use in diesel cars such as the Toyota Auris 2.0 D-4D, the EA60 is used by Lotus in the Evora, Evora S and the V6-engined Exige S.
The EA60 is used with two different gearsets, the standard one as used by Toyota and a 'Sport' ratio set.
