the tranny for the LX? I have no idea... would a 7th gen engine accept an older d series tranny?
You could get a quote for a new one from
www.HParts.com for a new one though...youd also need the clutch obviously, as well as the shifter arms and the shifter itself, pedal, hydro system, etc...
Id really suggest checking some of the junk yards (probably without much luck in Michigan...) and see if there are any wrecked 01s w/ a manny tranny...good luck...It wont be cheap...
