A 2001 S40 has become available locally. Normally I wouldn't bother with the Mitsubishi collaboration but I've been wanting a small commuter and at $400 this car is cheap enough (and the seller seems honest enough). 144K miles on the clock.

He says there's a couple engine codes that he couldn't figure out and a transmission speed sensor code that corresponds with the speedo going in and out. He says it sometimes drives perfectly, other times "the transmission can shift rough".

It has at least one other issue driving the cost down (a rope serves as the drivers door handle) but I'm wondering if the tranny makes this car a lost cause? I gather that the AW55 has a poor reputation (at least in the early 2000s) but am ignorant on the symptoms and fixes.

Walk away, run away, or tranny flush and smile?

Thanks!
Will
