I am new to the toyota world, I recently just bought a 2003 toyota corolla experiencing manual transmission issues.
Its a regular Corolla S model and I am looking to swap in the 6 speed transmission from a Vibe GT.
Is this possible without doing anything major?
I'm surprised more people haven't attempted this, I have been searching google all day with no luck.
That's an interesting question! I would suspect its possible' but there would likely be one or two real gottchas. The cv axles would likely be different. The clutch master cylinder would need to have the correct displacement to work with the 6sp slave cylinder. The bolt pattern might be different since the 2zz is a different block casting than the 1zz you have now. Then there's the matter of the compatibility of the 6sp input shaft, clutch components and flywheel. Finding a good 6sp might not be that easy. Even if it was easy to do this swap, the performance gain wouldn't be much. All this negative stuff aside, it would sure be cool if it works!

Interesting, you bring up alot of the issues and concerns that I have, mainly I wanted to see if the block castings were different. The main reason I'm considering this is because I came across a used 6 speed tranny for a good price and wanted to see if it would be a fairly simple swap. I'm used to the Honda world I guess where everything is interchangeable and where everybody has done the swaps a billion times.
Thanks for your help!
Why would you want to do that?? You will waste so much money for something that reduces daily drivability, fuel economy and does not improve performance???
The final drive ratio in the 2ZZ-GE is extremely short geared at 4.53:1 versus 3.8:1 for 1ZZ. Plus 2nd through 5th gear in 2ZZ are also shorter than the 1ZZ 2nd through 5th gear.
Where is the problem?? Problem is 2ZZ rev range is up to 8400 rpm while 1ZZ revs up to only 6400 rpm.There is a huge 2000 rpm gap there, which is why the 2ZZ C60 transmission is such short geared because it allows to rev up as fast as possible without compromising on the speed range per gear.
Putting such short gear with only 6400 rpm will drastically reduce your speed range in each gear. For example, instead of first gear going up to 50 mph, it will only go uptill 34 - 35 mph. You will be shifting way more than you are accelerating.
If you really do want to swap the transmission, get the Celica GT 5 speed manual, which has slightly shorter gears than the Corolla 1ZZ transmission, but still has a similar 6400 rpm rev limit so you will get better gear ratios.

Do a search on 9th Gen Corolla as it has been done. Also, if you have the money, I would call Monkey Wrench Racing as they have done a few swaps and sell the 3.9 final drive trans.

Axles are different.
Master cylinder is the same.
Bolt pattern is the same.
Input shaft is the same.
Clutch disc is the same.
Pressure plate is the same bolt pattern, but heavier, would bolt onto 1ZZ flywheel.

uhmmm. ok, thanks for the warm welcome to the site... I'm asking if it is something simple to do is all.

Thats the answer I was looking for, thank you sir!
Sooo, really this is a fairly simple swap... all I would really need to do is make sure i get the axles from the vibe GT correct?
Good Lord, dude.... you ask a question.... you get an answer with the why's and what-for's, and you come back like you've been flamed? Grow up.
Yeah exactly... I asked a question, so answer it. No where in my original post did i ask what the gear ratios were, obviously I understand that a 6 speed transmission is going to have me shifting more, it only makes sense.
I don't need anybody telling me that it makes no sense and that it will be a waste of money because you have never done it before.
I asked a question, either answer it or dont post... simple?
Your answer is "yes" and in your situation the swap should actually be somewhat simple since all you'll really need is the transmission itself and the driveshafts for an Xrs. I just went to Advance autoparts for my xrs driveshafts, GSP brand, and I think they were somewhere around like 70 bucks each. Also, there would be some performance gains by swapping in the 6 speed, more torque multiplication, but your rpms will sit higher cruising on the highway and stuff so your fuel economy may drop if you do a lot of highway driving.

Cool, so yours is all complete now?
how come more people have not attempted this if its a fairly simple swap?
