Excuse my stupidity but how does a 4L80E affect California Smog laws?

FWIW, I have cryo treated rotors and pads also, same set-up as Bish

Not stupid at all. California smog laws are confusing as hell. Technically, ANY change from a stock part or program without a CARB OE number is illegal. That means computer program, shift rpm, gear ratio, converter lock-up, as examples. My truck has already been "profiled" because of it's age and mods on previous inspections as a potential "gross polluter" and I have to go to "test only stations" to renew my registration. That's like secondary inspection at the border. I phoned a "smog referee" to ask about changing trannies. He said if I want an answer in writing the answer is no-way, but if I change it and the engine sniffs ok, doesn't throw a SES light, and no crime fighter sees the bigger tranny, I'm ok. That wasn't reassuring. So I'm in limbo about changing and still fighting with my 4L60E. By the way, a TH400 is most likely a felony.-joke

AintNoHo thank you for clearing that up. I just didn't think changing over to another factory trans violated the smog laws since it is offered in other trucks. I figured it was carb certified but since you have the 93 Blazer I can see how it might not pass.

an 80 will also eat up more gas than a 60

Trey- Cryo does claim more wear resistance- (gears last longer and turn with less friction), in addition it claims greater ductility (bleeds off heat like aluminum to prevent heat failure) and greater tensile strength (takes more pressure before it fails like a high tensile bolt). At temperatures near absolute zero the carbon flows to the flaws in the metal surface and on reheating crystalizes into a hard bond. That's why best results are with high carbon metal and plastic. Cheap steel doesn't get good results. Cryo also works to a lesser extent with aluminum but I don't understand why. Those are the claims, I'll see for myself if it works better than the fuel line magnet and octane rearranger. Maybe they'll claim I have cheap steel.

my old boss, when i did some motorsports stuff, told me cryo was useless in a trans because it did little in increase strength. safe to say he knew his stuff. Dont exactly get to be a VP of engineering with bullshitting.

made sense, because wear and tensile strength arent always hand and hand.

I dont know why they do it, but just because they do it doesn't mean its done to make them stronger. might even be a "make you feel warm and fuzzy" or increase wear resistance thing
