In my recent recurrent training, we had a discussion about the differences between the -10T and the -10. I didn't realize how different they are internally. My simplistic understanding was that the main difference was the lack of SRLs on the -10T, but apparently that's by no means the only difference.
Apparently, the -10T is only a different #1 turbine wheel (shared with the -10), EGT, and burner can... the rest of it is -5. The -10, on the other hand, is completely different.
Since the -10 is still in production, that should mean better support for the true -10 engines?
