Hi, new member here. I own a 2014 super bronco model# 13wq93kp011. It has a tuff torq k46cb transaxle and I would really like to replace it with a k58. My question is I'm not sure which k58 would work. Does anyone know if mtd part# 918-07233 would work in this machine without major modification. Sorry to be so long winded, it's raining where I am. Thanks!
