Tranny swap 5 to 6 questions.

Well, the tranny on my 5 speed 03 matrix base model crapped out.
I've looked all over here and a couple other sites and MOST say it's a direct swap over. But I believe I read here where one person mentioned the CV axels being different. What's the general consensus.
So, other than that, new clutch, new 6 speed (from an 07) the rest is direct bolt up to my understanding?

direct swap. you can reuse the CV axles.

What car has a 6-speed in 2007?
The 6-speed that fits the Vibe/Matrix/Corolla is the C60. If you've got a C65 from an MR2, you might be in for some trouble.

Hi y’all,I’m a new bee here. I have been reading the postings, but never posted once. I actually have the same questions as the above authors.
I have a 2004 Toyota Matrix base model ( the same as vibe 1 zzfe w c59/ manual tranny),105k miles. My tranny went kaput on me, started w loosing reverse gear first, now only got the 1st alone lol. So, the replacement is very scarce, if any, it will be 200k miles or more on it, therefore I look for c60 jdm replacement. My worry is like everybody else, needing a modification on it.
I saw denvervibe did it back in 2017, but I couldn’t contact him/her. I just like to know if anybody has done it here, and what else are needed beside the tranny it self??.
I really appreciate y’all,
Thanks

No other changes are need other than the transmission, and the shift knob if you want to make sure you know which gears yours in LOL.

Hi y’all,
Finally, I have swapped the old c59 with the JDM c60 on my trix. I already drove around 4k on it. I paid someone to do the swap. It looks like just plug and play. CV axel looked good, so I didn’t get the new one. Just used 6 spd clutch kit. Nothing else change.
I like to thanks every one on this project.
Btw, the others who have done it, I have a question. Did y’all get the 6th speed (actual 6th gear), because I only have 5 spd like the original. I run 75mph@ around 3200 rpm. Is it sound right ?
Once again, thanks y’all

Trix. You should be closer to 3400 RPM @ 75 MPH. Here's my 2004 Vibe GT in 6th gear.

For the first gen Vibes and Matrixes, the manual transmission gear ratios are :
5 speed
1st : 3.17
2nd : 1.90
3rd : 1.31
4th : 0.89 (overdrive)
5th : 0.73 (overdrive)
Reverse : 3.25
Final Drive Ratio: 3.94
6 speed
1st : 3.17
2nd : 2.05
3rd : 1.48
4th : 1.17
5th : 0.92 (overdrive)
6th : 0.73 (overdrive)
Reverse : 3.25
Final Drive Ratio: 4.53
To map RPM to MPH:
(Engine Revolutions per minute * 1/gear ratio * 1/final drive ratio) *
tire circumference (in inches) * 1 foot/12 inches * 1 mile/5280 feet * 60 minutes/hour = vehicle speed in MPH
The stock tire on a 5 speed are 78.2 inch circumference
Since the top gear ratio of both trannies is 0.73, and assuming the same size tires, the 6 speed will run slower at the same rpm than the 5 speed due to the difference in the final drive ratio.
at 75 MPH, the engine should be at about 3350 rpm in a six speed, compared to about 2920 rpm for 5 speed, not including variations in tire size/inflation, speedometer accuracy, etc

3200 rpm @75 mph is a closer match to the 6 speed, but I don't understand you only having 5 speeds
When you walk through the gears (say with engine off) which shift pattern matches your car? (ignore the diagram on the shift lever if you still have the one for the 5 speed)

Hi Joatmon,
Thanks for responding. When the engine is off, the shifter goes like the first pic you have (5 spd original). So, I’m just confused because there’s a stamp of c60 on the tranny casing when I bought it. What do think that happened or done wrong? Thanks again.

Just to confirm, reverse is to the right and down?
It sounds like you got a 5 speed, which might be best anyway. The 6 speed is geared lower with an extra intermediate gear to help the 2Z engine to rev high enough to hit lift more easily, but since it's geared lower, cruising down the highway the engine will rev higher than in a 5 sped, so there's be a small hit to gas mileage.
The 5 speeds in Vibes and I assume Matrixes also had a higher rate of bearing failures, but I haven't heard that continued into the later years, so an 07 5 speed might be more reliable than your original 04.
I know that Pontiac dropped the 2ZZ 6 speed Vibe GT in 2007, the last ones were 2006 models. It is likely that Toyota did the same thing, and perhaps there were no 2ZZ 6 speed Matrix XRS's. Doesn't explain how you got a 5 speed C60 out of an 07 Matrix though.

Hi again Joatmon,
Thanks for the response.
My question really is, the new tranny swap it has c60 stamp on the casing, but it is only shifted like 5 spd ( your first pic pattern). Do you think there’s something wrong during the installation since I don’t do it myself? Do I need to change the shifter mechanism inside the console with 6 spd one? That’s where I’m confused.
Thanks again.

The shifter is free floating. It has two cables attached, effectively one that controls left to right, and another that controls forward and back, limited in movement only by the levers on the tranny. If the shifter was disconnected from the tranny, you could swing it in a circle.
There is nothing an installer could do to change a 6 speed to a 5 speed. It would require swapping a bunch of transmission internals, which, if possible, would be a ludicrous amount of parts and labor. Might be an interesting project for someone with too much time and money on their hands.
My best guess is that the transmission came out of something like a Celica or a Spyder, and not a Matrix or VIbe. Apparently 5 speeds that are stamped C60 exist - see
https://www.jdmcalifornia.com/product/c ... gbH2haqV5o
There's also mentions of such a thing on wikipedia and in some mr2 spyder forum threads
You got the transmission from somebody, ask them exactly what car it came out of
I can't find clear definition of the gear ratios for such an animal, and some of the internet hints at a chance that some of those might have a limited slip differential, which would be cool to have
