Depends on what scanner your using. Most regular scanners will show regular DTC trouble codes (P codes). A Tech2/3 or reading via HPT Ecm scanner will show you the extended codes (T, U and BCM codes), and it will also show gears.

I'll have to check back through some of Clinebargers posts, he's the resident trans expert and has previously posted his preferred sources for trans harnesses.
