Owner complaint summary

Transmission issues that are in line with what seems to be a well known 10R80 issue with a poorly engineered CDF drum. Transmission will randomly shift from a high gear down to first generating a ton of noise and impacting the handling. It has not become a permanant failure yet but is an extremely well known issue that always results in a transmission rebuild with updated/correctly engineered components at MY expense. I am worried it will cause a rear wheel lockup or a damaging amount of engine rpm one of these days. It is sporadic and isn't something that has been duplicated by a technician due to it being isolated and completely random in occurrence. It definitely seems to do it more often when it is cold out.

This is an owner complaint filed with NHTSA (ODI #11755994). It is not automatically an official recall, investigation outcome, or manufacturer admission unless the complaint text itself describes one.
