Sourced a hurt S197 transmission to rebuild. Getting mixed messages from my research on what needs to be changed to work with an S550. I know the driveshaft flange needs to be changed from 4-bolt to 3-bolt, and the shifter assembly is different (but I *think* the MGW I’ll be bolting on negates this issue), but is there anything else? VMP lists the tailshaft being different, but when I reached out to Mike @ Autonation White Bear Lake, he told me the part numbers are the same for 11-14 and 15+. Has anybody done this and can speak from experience, or point me in the right direction? Thanks!
