Has it ever been cleared up if the '02 or newer trucks ALL come with "corvette" servos already in them? Seemed to be a lot of discussion in some of the threads, but I couldn't find a definite answer.

I'll be doing my torque converter soon and wanted to do some of the easier improvements while the tranny is apart.

Was reading an article that suggested (among other more expensive things):

- The corvette servo
- Transgo Torque Converter Clutch Modulator
- Aluminum forward and 1-2 Accumulator Pistons
- Replace steel check balls w/ composite plastic

?...Thoughts...?
