Toyota C Series Gearboxes for the Celica 7th (1999-06)

Toyota C Series Gearboxes for the Celica 7^th (1999-06)

This article is about the various Toyota C series Gearboxes that are used in the Toyota Celica 1999-2006 models.

Four gearboxes were used: 

C56 5 speed

C60 6 speed

C63 6 speed

C64 6 speed 

You can see the comparison of them in the last table but first I will describe them:

C56

The C56 is a 5-speed gearbox that was mainly used together with the Toyota 1ZZ-FE engine in the US.

Applications:

Toyota Celica GT

Toyota Corolla

Toyota Starlet Glanza V

Toyota Corolla Levin AE101 / Toyota Sprinter Trueno AE101 - later years

Toyota Corolla Levin AE111 / Toyota Sprinter Trueno AE111

Toyota MR2 Spyder (US/Japan) (mid-engine application)

Toyota Vios turbo

Toyota Vitz

Geo Prizm GSi (1990–1992)

Elise S (2007-2010)

 

Differential Options:

C56-01A: Open Differential

C56-01B: Torsen Limited Slip Differential (LSD)

C56-03A: Open Differential

C56-04C: Limited Slip Differential (LSD)

 

Gear ratios for this transmission:

1st	2nd	3rd	4th	5th	6th	Reverse	Final
3.166	1.904	1.392	1.031	0.815	-	3.250	4.312

 

 

C60

The C60 is a 6-speed gearbox that was mainly used with the Toyota 2ZZ-FE engine in the US.

Applications:

Toyota Celica GTS / T-Sport, 1999–2005 (US/Europe)

Toyota Corolla XRS 2005–2006

Toyota Matrix XRS 2003–2006

Pontiac Vibe GT 2003–2006

Lotus Elyse with the 2ZZ-FE?

Differential Options:

C60-02A: Without Limited Slip Differential (LSD)

C60-02B: With Limited Slip Differential (LSD)

Gear ratios for this transmission:

1st	2nd	3rd	4th	5th	6th	Reverse	Final
3.166	2.050	1.481	1.166	0.916	0.725	3.250	4.529

C63

The C63 is a 6-speed gearbox that was mainly used with the Toyota 1ZZ-FE engine in Europe.

Applications:

Toyota Celica ZZT230 with the 1ZZ-FE engine 1999-2005 (UK, Europe)

Gear ratios for this transmission.

1st	2nd	3rd	4th	5th	6th	Reverse	Final
3.166	1.904	1.310	1.031	0.864	0.725	3.250	4.312

C64

The C64 is a 6-speed gearbox that was mainly used together with the Toyota 2ZZ-FE engine in Europe. The main (and only?) difference with the C60 gearbox is its shorter 6th gear ratio (0.815) compared with the one of the C60 (0.725). The 6th gear of the C64 has higher rpm in the highway but has better torque than the 6^th gear of the C60. The 6th gear parts of the C64 and C60 are interchangeable, so you can install the 6th gear ratio that you desire. Because of this there are many used C60 C64 gearboxes that have a different 6^th gear ratio than their original, adding more confusion to the prospect buyers.

Applications:

Toyota Celica T Sport (UK)

Toyota Corolla Sportivo (Australia)

Toyota Corolla T Sport (UK/Europe)

Toyota Corolla T Sport Compressor (UK/Europe)

Toyota Corolla Fielder Z Aero Tourer (Japan)

Toyota Corolla Runx Z Aero Tourer (Japan)

Lotus Elise (manual mid-engine application)(US/UK/Europe), 2004–present

Lotus Exige (manual mid-engine application)(US/UK/Europe), 2005–present

 

Differential Options:

C64-01A: Open Differential

C64-01B: With Limited Slip Differential (LSD)

 

Gear ratios for this transmission.

1st	2nd	3rd	4th	5th	6th	Reverse	Final
3.166	2.050	1.481	1.166	0.916	0.815	3.250	4.529

 

Synchros of C56, C60, C64

“...There was a design change to the 3rd and 4th gear synchros in 2003/2004. Your 3rd and 4th gears, synchro rings and 3rd-4th hub ring must all be either early or late. If you have an early transmission then during a rebuild you can upgrade to the late style synchros which are a bit better in durability and performance…”
