2010 Camry 6-speed transmission (EB62) internal pics & information

[Gouky]

alright guys, i know this idea has been kicked around a bunch but i'd figure i'd give everyone some hard numbers.

i had my EB62 apart today because some after about 3000 of hard track use, a mis-shift broke a shift fork finger (definitely abuse, i don't think it's a design flaw)

the good news for you guys is i took pictures and measured a bunch of stuff. the other shafts and gears in these pictures are E153 stuff. i had it laying around and i figured it was a good strength comparison.

first the numbers:

EB62 gear widths (estimation of gear strength):
1st: 16mm
2nd: 16mm
3rd: 14.5mm
4th: 14mm
5th: 14mm
6th: 16mm

E153 gear widths:
1st: 17.3mm
2nd: 18.3mm
3rd: 18.3mm
4th: 19mm
5th: 18mm

the other thing that affects strength is the helix angle. the E153 has a lower helix angle than the EB62 everywhere but 1st gear.

while i did not get the numbers for reverse since the entire gear does not engage, it is clearly obvious that the EB has a significantly weaker reverse.

both ring gear widths were 29mm.

the input shaft's neck down diameter on the EB62 measures 22mm and the E153 measures 24mm.

both shafts's smallest diameter between both support bearings was 27mm

the EB62 has a much longer unsupported length of 230mm where as the E153 only has 190mm

and now onto the pictures:

here are the input shafts:
top is EB62, bottom is E153

here are the output shafts:
left is EB62, right is E153.
sorry the gears are off the E153, that shaft is a leftover after a final drive change.

1st gear width comparison:
full shaft is EB62, individual gear is E153

overall, I feel that this EB62 transmission is much stronger than I originally thought. I think i'd feel good about putting it behind a 2GR-FE monster, especially if it did not see the drag strip. though i am concerned for how far 3rd and 4th gear are from any supporting bearings.

overall, it's a very nice transmission and it is very easy to work on.

Excellent information, thanks for sharing.

Do you think the EB62 would be as strong or stronger than an S54?

[Gouky]

definitely stronger than the S series and the C series. but not as much as the E series

[RobYob]

Fantastic, my car has an S54 hooked up to a lightly modded Gen 3 and has run well (touch wood) for years including hillclimbs and trackdays, if the EB box is at least as strong it sounds like an excellent upgrade option.

Thanks heaps.

[RobYob]

DAMN! That transmission doesn't appear in any Aussie Carmy or Aurion models, so unfair!

[Gouky]

did you check the Scion Tc? it has the same box with a slightly different set of ratios.

[RobYob]

Scion brand doesn't exist in Aus either.
Can only hope the EB boxes go into the next model Aus Camry or a Corolla.

Really appreciate the help anyway, thanks.

[RobYob]

oops double post.

[snowtigger]

We don't get the aurion so can't have the supercharger bummer.

[Gouky]

We don't get the aurion so can't have the supercharger bummer.

*lol* that's a good point. we've got something to trade!

[RobYob]

lol you wouldn't want it, non-intercooled supercharger is pretty fail for a start.
No idea how many T(u)RD Aurion's even got made (quick websearch says less than 600), it was overpriced, underpowered and wrong wheel drive.

[snowtigger]

That's were we need info on injectors and a supercharger to experiment, this idea with as we can make it proper rear drive.

The lotus evora has the same system as the aurion we just don't want to pay lotus prices.

I mostly just want the ECU that is calibrated for boost.
