Good call. Can someone tell me the names of all the different 5spd and 6spd MANUAL transmissions so I can edit it in properly?
The way I understand it, the best options short of custom gears would be 1) cryo and 2) shot peening.
Cryo is generally cheaper while the shot peening results in a stronger product.
What is WPC?

What parts specifically should be cryo'd or shot peened.

i kno. i just want a general answer.
I think specifically they treat pretty much everything. Almost any part that is under stress or subject to friction can be subjected to one of these hardening treatments. In the case of transmissions, the norm is to disassemble the entire transmission and ship it out.
Here's a link with an explanation of the cryo: http://www.allfordmustangs.com/foru...-gear-hardening-thru-cryogenic-treatment.html

Honestly, I've never invested much interest in building an automatic because I've only owned one and I swapped it out for a manual. Lol
Generally an auto can see performance gains with better servo's, higher stall converters and tighter springs. But nowadays with TCM, I am clueless. Add to that that I've never souped up a FWD before my Sonic.
My father owned and ran a transmission shop for 20+ years in which he also built up trannies for his personal hot rods. I'll pick his brain ASAP, and share what I find out about building up both modern auto and manual transaxles.

Beefing up autos can be anything from a shift kit to a retune depending on the application. For the automatic Sonic you should see huge gains from the tune alone. To make it stronger you would use better clutch disks and maybe upgrade the gears if need be. I couldn't tell you much about beefing up a manual besides clutch stuff and things already mentioned.

The 6t40 and 6t45 are fully compatible with one another from what im reading.and that will move us up in HP and TQ ratings by a good bit. See my post http://www.sonicownersforum.com/forum/t5892/#post119174

Not having had one of the manuals apart yet, I can only give examples of what I've experienced with other gearboxes.
First, here's what little we know about the M32 6 speed:
In Europe it is used with the 210hp 1.6T that comes in the Opel Corsa OPC Nurburgring edition.
Opel Corsa OPC Nrburgring Edition hatchback - Car Specs - Performance, Engine, Comfort, Weights, Security, Photo Gallery
This suggests that it still has some head room left because GM typically overbuilds drivetrain components.
How can it be made stronger?
- Shotpeening the gears. For even better results, follow this up with the next process.
- Cryo REM the gears, shafts, bearings, and anything else that makes metal to metal contact. REM Gear Polishing, Atlanta
(This process is also good for cranks, rods, cams, rockers, CV joints, etc.)
- Custom made steel syncro rings. This shouldn't be necessary, but I'm throwing it out there anyway.
Until someone goes crazy with the horsepower and blows one apart, it will be hard to determine where the failure point will be.

theenico has arrived with valuable info. But I'm still hungry for moe.
The Cruze MZ0 is a direct swap, correct? I remember hearing somewhere that it's rated for slightly more hp/tq than the M32. If so, I may start seeking one out for an overhaul and shot-peen.
Also, what are the ratios on the MZ0?

Ditto, but the 1st to second drop is still huge! But i like 3rd and 4th gear much better
