2006 C6 transmission
Team I lost 5/6 gears in my T56 6 speed transmission. The code stamped on the side is TUET 4430 and 61UCD T003002. I am finding a lot of T56 out there to put in my car but have different codes. Can I interchange as long as they are a T56 and 27 spine.

You most likely stripped the splines that keeps the 5-6 driven gear on the main shaft.

Are you sure it is not a shift linkage problem? It could be related to the internal transmission shifting components rather than a gearing failure, especially if you aren't hearing any bad noises coming from your transmission.
