5 Spd to 6 Spd Conversion DIY

[Bluevitz-rs]

These are the studs I had to fab up. The ones I had weren't long enough so I had to weld a bolt onto each.

[CrankyOldMan]

Wouldn't it have been easier to just get some threaded rod and cut it to length?

[Bluevitz-rs]

not really when your transmission is sitting on a bench in pieces. LOL

edit: it took me a whole of 5 minutes to flip the welder on and then grind and wire wheel them, so...

I chipped the teeth on one of the gears on my old box trying to remove it. There is bugger all room under the gear to get the legs of the puller in there.
A bit of creative grinding on a puller might let you get under there easier without damaging the teeth.

PS, zip ties don't work

^I remember that pic...

So you used a standard bearing puller like this or a 3-jaw puller like this?

[CrankyOldMan]

I didn't take pics of my C56 when I was tearing it down, but the 5th gear hub can be removed with a standard "bolt puller" or steering wheel puller set. The two holes in the hub should have M8x1.25 threads. Once you get the hub off, you can get a bearing separator on the upper groove of the 5th driven gear. Once that comes off, the 5th gear just slides off (it's on roller bearings). I'll try to remember to get one of the kids to take a pic of the C59 teardown.

So I was looking at the frame today when I changed my oil, and it looks like it's already notched the way bluevitz-RS did with his. I can't tell from the pictures, but it looks like the Vitz frame is/was square first, based on the shape of the cut off piece. Perhaps there really is hope for the NCP91 frame and a C60?

[Bluevitz-rs]

Just measure the gap between the stock tranny and the frame. That'll let you know if it'll fit or not. I added about 1" of room. When I first put the 6 speed on the motor and tried to get it up into position, it JUST hit the frame by about 1/4 inch or less.

[CrankyOldMan]

So it was originally notched, but you added more room? I would have taken a pic, but I didn't have a camera on me.

[Bluevitz-rs]

No it was square.

[CrankyOldMan]

Hmm, Now if I could just get my hands on the end cap for a C60...

[Maitre_Te_Te]

I think that all it's fine because an TS can have 1.8L with an other tranny!
Than the engine bay is larger than echo for this engine! I wait your reply.

[CrankyOldMan]

The Euro T-sport 6-speed uses the EC6X series transmission with the 1.8L 2ZR-FE engine, which is a two piece casing instead of the C-series three piece design. I would guess that the gears are also narrower than the C5X/C6X series, but I'd have to have them side-by-side to verify. The gear shift cable is also unique to the Euro T-Sport, as are the mounting brackets that mate with the body (the engine/transmission side of the mounts are the same as the xD).

Possibly getting a little off-topic, but does anyone have a comparison of the stock NCP91 5-speed to a JDM AE92 Corolla 5-speed (C52?), and know if it will fit?

Seems like an odd swap. The C52 has a taller 1st gear and marginally shorter final drive, the rest of the ratios are the same as the Yaris C50.

Thanks for your contribution, Great info!

I am thinking To Get a C160 LSD trans from UAE It's Available, Next Visit i will get one for my Echo i have a Question Dose the C160 transmission have a Code name on it?

The reason for my Qes is @ United Arab Emirates I No the Cars that carry the C160 trans but the thing is I have to buy the whole half cut car for the trans only, thy wont sell you the trans only.

I just buy Full Apex'e Coilovers for my Echo on the last visit.

[Bluevitz-rs]

I couldn't find any markings on the transmission that defined it other than it's physical size difference to the 5 spd. When I got it, I didn't know if it was LSD or not. And it wasn't. I just used the info on Wikipedia
