Ok. So to recap this for me, because of course, im a noob, it is possible to swap a +02 Camry 5 speed ring gear and output shaft in a 05-09 5 speed tC tranny? E350 being the scion tc and E351 being the Camry tranny...correct? And also if i wanted to i could swap an entire +02 Camry E351 in a scion tc?
thanks for all the research you guys have done on this, ive been following this thread for quite awhile and its actually refreshing to find some really usefull and knowledgeable info on here! props to yall,
Austin

 

Yes, if youre willing to press the old gears off the output shaft, and press them onto the new one then you can indeed swap the output shaft and ring gears of the two. One other option would be (since 5th is the only gear different between the two shafts, use the output shaft out of a 351 with the gears still on it, and since you have to pull 5th gear anyway to get the cases open, just swap the 351 5th gear onto the input shaft of the 350 when youre reassembling and swap the ring gear. Seems like an easier job as long as you check the preload on the bearings. Or yes you can just pick up a 351 and swap it right in assuming youre willing to drill and tap a few holes in the case (again i forget where, I want to say I had to do one for the rear motor mount and one for the pass side but i could and very well may be completely wrong on that as its been almost a year) . Or you can swap all the internals between the two.

Plenty of options.

 

I will make sure I get all of my shims/tolerances correct. I have access to all of the technical info I need, so it should be pretty cake.

I am about to purchase an E350 (camry transmission) soon, tomorrow if all goes well. So I will be doing my trd install, as well as the final drive swap. If everything works out, (which it seems like it will more and more each day) I will be more than happy to do this swap for anyone wanting it done.

 

Good to hear. Honestly it gets really easy after the third time lol. If I had the time Id do the same.

(quick note, 351 is the camry tranny code, some cases are marked 350 tho as thats the base design code, but the internals make it a 351)

but I know thats what you meant.

 

E241 is the Scion auto what is the camry auto code?

sorry ive been so outta the loop on this thread.. ok im back ...lol but no im not confused about it lol.. both the trannys i worked on were off tc's.. i know what im looking at lol...



also... before pressing in 5th gear and locking the tranny down i would do a little more homework on the 05 XRS ranny and the one of the older gen MR2 trannies and check out their gearing and final drives.. you can pull a much better cruising speed at 70-80/rpm ratio then what the tc currently offers. But you WILL have to get some CNC parts made if you incorporate any of those parts.. especially trying to squeeze in the mr2 final drive which technically can get you 175 mph at 8600 rpms =D (roughly because my math might be off a tad lol)

 

Heres the ratios for you Pete. And yes I acquiesce, we have a drive gear but it ain't used for anything in our tranny. MR2 turbos gear ratios (E153) are
4.29 FD
3.23 1st
1.91 2nd
1.32 3rd
.920 4th
.731 5th

Its actually a shorter FD, so IMHO that would be a pointless swap, now 2nd is promising for those whod want longer legs to hit 60 in second but with the 4.24 FD. Ours stock is a 2.045.
Third is negligibly longer, 4th is actually a fair bit longer, and fifth is the same gear as the Camry trannys fifth anyway. Personally I dont know how fitment would go in regards to swapping different gears over, but Toyota has a habit of not changing a good design much. Now something im interested in, the MR2 turbo came with an optional LSD from the factory, its notoriously kinda soft as far as lsd are concerned and might possibly require remachining of the splines on our drive and halfshaft, But I personally like the feel of a partially locking diff in an FWD car and may look into this soon since the wilwood BRK seems to be doing well so I can cross that off my list. Oh and good call on the XRS ratio, I forgot it used our engine for a few years.

However the 05 06 XRS used the C64 (the notoriously weak 6 speed from the 2zz celica) so id personally shy away from that and look more at the 2AZ corolla XRS from 07? on. They feature a 350 series with our final ratio but with the .731 5th already included. Basically they have the tranny im planning on turning mine into. So far I cant find a specific code on this model of 350 but keep your eyes open ppl as this is a fairly promising gearbox for those who wanted just a little more leg on 5th gear without losing the peppiness in the lower gears. Specs and ratio based speeds for this mode are located on previous page.

 

E153 Speed @ 6500rpm
Final Drive = 4.29
1st = 3.23 = 34.4mph
2nd = 1.91 = 58.1mph
3rd = 1.32 = 84mph
4th = 0.92 = 120.6mph
5th = 0.731 = 151.8mph

Now, lets say I borrow a few gears from this transmission as well with 0.944 as the final drive:

Factory
1st = 3.538 = 34.1mph
2nd = 2.045 = 59.0mph
3rd = 1.333 = 90.6mph
4th = 0.972 = 124.2mph
5th = 0.775 = 155.8mph

"Modded"
1st = 3.230 = 37.4mph
2nd = 1.910 = 63.2mph
3rd = 1.333 = 90.6mph
4th = 0.972 = 124.2mph
5th = 0.775 = 155.8mph

For people with built blocks (using modded gear ratio's), 7500 rpm and 8000rpm:
1st = 43.1mph/46.0mph
2nd = 72.9mph/77.8mph
3rd = 104.5mph/111.5mph
4th = 143.3mph/152.8mph
5th = 179.7mph/191.7mph

I don't know about you all, but that is fast enough for me! If possible, I would love to have the "Modded" transmission, but I have no idea if the gears would fit, and wouldn't know where to source them other than getting another complete transmission. I may look up info tomorrow if I have time on some measurements on the MR2 transmission, if I can find any. If you have any info pete, please share either here or through pm!

 

I swapped in an 09 camry 5 speed into my xb2, and I brag about how great my gas mileage is.

I also talk about how great the quaife lsd is in the snow...

Does that make me a ricer?

 

You realize the last post in this thread is 2010 right?

 

so it shows that everyone is keeping their tc transmissions but swapping out the internals for E351 with the LSD no problem....now i cant find any link online to purchase the E351 internals,can someone help! !!

 

Don't bother swapping internals. Just get a good condition used one out of a Camry. I bought one out of either an 03 or 04 from a local junkyard for $200. I took it apart, installed the Quaife/TRD LSD myself and have been running it for a about 3 months now. The E351 doesn't come with and LSD. You need to buy the one for the Scion tc and install it. Besides the gearing and the speedometer pick-up that isn't needed for the tC the trans cases are identical.

 

but do you have to build custom mounts for the camry tranny or will it bolt right into tc chassis just fine??

 

Mine bolted right in. The trans case is the same. Just swap the mounts over.

 

ok thanks for the info on this you have been a huge help...

 

Not a problem. If you plan on installing an LSD, there's an excellent write-up in the DIY section by a former member named J3st3r or something like that, that details all the steps on how to disassemble and reassemble the trans. This is what gave me the confidence to tackle it myself. I put a couple extra suggestions at the end of that thread to help out anyone that may be interested in doing this as well.
