This has not been my experience. The highest torque and most abused gearbox i have in the field handles about 750-800 ft/lbs in a racing environment on massaged stock internals with a clutch type LSD. This gearbox has been abused and drag raced repeatedly and the only issues have been is first gear is wearing and they are on their second ring and pinion (caught a slippery spot on the track.. Wheel spin then hooked up, chipped 3 teeth on the ring gear). So in a street setting the 01E can handle a respectable amount of torque. I've changed the first gears to make them more robust, and there is an 01E with a larger ring and pinion out there. The 01E probably has the best torque capacity per dollar of any production transmission out there. And if driven smartly will handle any engine it's attached to.
