So I'm here sitting at home thinking about transmission upgrades and I think "lsd". Then I remember that drugs are bad for me so I think about LSDs. So I start looking into the transmission codes and find that we run a F5MBD 5-speed manual transmission. I start changing the last character to see what turns up (taking cues from my previous DSM and Lancer/Cedia/Mirage experience) and find out that the 2011+ Lancer FWDs run a F5MBB 5-speed manual transmission. Also found the F5MBE from the RVR.
I tried looking further and found nothing in the way of differential part numbers. So I guess tomorrow or Thursday I'll just have to drop in at Mitsubishi and ask a couple of questions. Or a whole slew of them. Let's see what turns up.
I'm hoping on a similar or same differential part number. maybe clutch part numbers as well but now we're really dreaming. But I'll let you guys know what happens.
