120K on my 98 2.2L... drag raced, Road Coarsed, Auto-x, and wangan (lots of it). i have a 4EAT and yes i shift it like a manual when driving hard.
replaced Head Gaskets (due to them being blown) at 78K miles. replaced with cometics, no problems since.
transmission works just fine
while on the highways doing high speed runs yes i have pinged the rev limiter a bit... but i never ride it.
car revs to 6200RPM
