Default 4L60E power range?
does anyone know exactly how much power you can run through a unmodified 4L60E?

No.

Too many variables and they are not all created equally.

Some lose parts with virtually stock power, some go wheels up for awhile. You just never know. I lost a clutch pack in mine a couple thousand miles after camming it, with only 55k total.

All articles I've read says the dealer estimated it could hold 300-350 HP tops, but there are no guarantees.

I should hope so considering that some SLP versions come 345hp. It wouldn't be very smart to warranty something but not build the tranny to withstand the horsepower.

I lost a clutch pack and since I got the converter/temp gauge I never let it get over 210 at the track and didn't even go enough miles to need to change the fluids. Hard street driving was all it took.
