Camry gear ratios:

First - 4.24:1
Second - 2.36:1
Third - 1.52:1
Fourth - 1.05:1
Fifth - 0.76:1
Final - 3.29:1

Scion tC gear ratios:

First - 3.54:1
Second - 2.05:1
Third - 1.33:1
Fourth - 0.97:1
Fifth - 0.78:1
Final - 4.24:1

just some facts for thought...

to be straight up those camry gear #'s look good for a boosted car. You will lose some TQ. though......

unxpectederror

the more i look around it seems there are several different gear ratios they have used in the camry transmission
this is the gearing in the newer camry

3.538
2.045
1.333
0.972
0.731
Final Gear Ratio
3.944

basically looks the same with the exception of 5 gear.. hmm
so im guessing you would have to go with a older transmission to get the longer 1-4 gears
jsg93085 do you know what year you got those camry ratios from?

jsg93085

the ratios i posted were from a 2005 camry

and looking at the site again... it was from an automatic apparantly, but i dont think that camry's had a 5 speed auto...

unxpectederror

weird mine came from a 07

here is a mph break down of the ratios you posted these are at 6.5k rpms

camry
1. 34 mph
2. 61 mph
3. 95 mph
4. 137 mph
5. 190 mph (holy poop)

tC
1. 31 mph
2. 54 mph
3. 84 mph
4. 115 mph
5. 143 mph


idk to me the camry gears look better

do like rythm said greddy ultimate and there you go speed limiter and rev limiter increased done deal! and if your auto go manual point blank if not ask soflo how he has a built auto tranny and hes selling it to go to manual!!!

unxpectederror

lol you do realize that you would have to raise the redline to 7300- 8400rpms (depending on gear) to match mph out put of the Camry transmission right?

yeah that's not gonna happen on a stock valve train

im planning on raising my redline to 7 with just upgraded valves no springs or retainers.

unxpectederror

upgrading your valves alone isn't gonna help ya with increasing your redline. if i were you i would replace the springs and retainers well before the valves themselves ... though you could probably get away with safely increasing it to 6800-7000 with out even touching anything.

rhythmnsmoke

143mph? Must be without the speed cut. Then again, without the speed cut it's still higher than 143. You going to find yourself doing a LOT of work just for a couple of mph in the gears that you could have achieved by simply adding a management solution that could raise rpms.

rhythmnsmoke

No you wouldn't. 6500rpm would get you pretty close to those mph, except for the top speed.

And PLEASE tell me where you going to be racing at 190mph IF it can even get up to that speed.

I can see it now. You swap in the Camry tranny and then brag how your tC can go 190mph top speed. That = Ricer.

rhythmnsmoke

You can go to 7 on a stock valve train. It's been done and it's not going to blow up on you like you might think. I'm going to raise mine to about 6700-6800.

unxpectederror

dude all them ratings where done at the tC's 6500redline... ive done all the calculations with a gear ratio converter and they are correct.

and i already stated that you could do about 7k on the stock valve train no need to restate it like i was denying it lol

here is the tC's gear vs speed ratios if you where to increase the redline to 7k

1- 34 mph
2- 58 mph
3- 90 mph
4- 124 mph
5- 155 mph

quite a bit off from the camrys in most except for 1st

and here are the rpms in which you would need to increase it to in order to match the camrys mph in each gear

1- 7000
2- 7300
3- 7350
4- 7700
5- 8600

and obviously i wouldn't be racing up to 190mph however it would make a fantastic gas saving cruising gear on the highway.. you would be cruising at only 2250 driving 65mph instead of 3k like with the stock gears

and whats talk of all this extra work.. im gonna be taking the transmissions off anyways in order to put my flywheel and clutch in. so if the transmissions housings are the same there is no need to spend any extra money other then on the transmission it self which is fairly cheap.

Your numbers are off. I'm going by an actual tC that had increased redline above factory. If you left the redline stock and remove the speed limiter, the Mph is more around 147mph.

Here is the bottom line:

tC increased redline + speed limiter removed > tC with camry tranny installed.

On top of that you still going to have the speed limiter set at 127mph, camry tranny or no camry tranny. So, you STILL going to have to take that off via an external ECU/module.

Remember, we are limited to 127 via Electronic means, no gear.

But do it man, not saying it wouldn't be interesting to see what it will handle.

unxpectederror

lol dude its like your not even reading my posts

they are 100% right if you where to take off the speed limiter, 5th gear would physicly top out at 143mph with the stock tire size ratio not 147. you could get to up over 147 if you had the wrong size wheels and tires though. 215/45/18 would bring you to 149mph but then your speedo would be off by about 4.1%

and obviously if you have a turboed tC your gonna already have some sorta ecu management thus you would probably already have the speed limiter removed.

the lengthen gears of the Camry is more suited for drag racing in a turboed tC. with the camry trans you only need 1 shift to reach 60 but in the tC you need 2 shifts. this will make for faster 1/4 mile times. not only that but if you had the Camry transmission and raised the redline to 7k you wouldn't have to shift out of 2nd until 66mph. i don't understand how you don't see the benefits in this

rhythmnsmoke

I wasn't talking stock tire size, my bad. Do you feel safe running stock tires at 140+...I know I don't.

90% of the turbo tC's have Emanage Blue. Does not remove the speed limiter. The other 10% have an F/IC, which also don't remove the speed limiter. So, I stand by what I said. There are only a handful that have standalones or the Emanage Ultimate (I am one of those few).

I stand by my prediction. Prove me wrong not with numbers, but actual performance when it gets in the car.

jsg93085

This has been discussed elsewhere as well (ystc.org). Swapping for a Camry 5spd is only going to net you higher MPG due to the longer gearing of the Camry transmission.

Anyone with F/I may not have any issues with the longer gearing, but on a stock motor, the tC will feel slower compared to a tC with its stock transmission.

Some have suggested swapping out specific gears from a Camry transmission (i.e. 5th and Final), but I don't recall anyone ever posting that they did so...

m6ar2cel6oTC

look just go for the camry swap and see how it goes. lets see if you say i should have gone with raising the rev limiter and speed cut lol or say F*** ultimate and get a swap lol!
point is you'll never find out anything unless someone did it and no one has so go for it. worse comes to worse keep your stock tranny incase you run into any problems and have to go back. Keep us updated!

whorok305

I thought that the camry tranny only had a longer fd. Other gears were the same.
