TRNW-2: 6L hp tuning

[Phil Materi]

We are turning TCC off in 1,2,3 and not adjusting any apply or slip speeds.  We live in a city with a lot of stop and go traffic, and very hilly terrain.  We first tried changing other TCC parameters like others have mentioned and nothing but complaints.  Now that our local TC build shop has figured out how to make the TCs last without redeveloping a shudder, they work well with just turning TCC off in 1,2,3.

Those who are tuning, I know it's popular to command lock up only in 5th and 6th.  Do any of you let it lock up in 4th also?  I just tuned one and left 4th strategy alone, no lock up 1-3 and zero slip speed in 5th and 6th.  Just wondering what most of yall do.  It felt great and not sure if it really matters.

Thanks,
