H&S Tranny Tuning OR Leave it Stock?

Downloaded H&S Tranny Tune. Only have about 60miles on it since I downloaded it. But 1st-2nd gear is stiff. The other gears are softer after driving today. The only thing I dont like is that my 4-5-6th gear shift point are about 5mph higher than stock. And that the TC doesn't LOCK till about 4th gear. Does that stay the same or does the tranny eventually learn and lock earlier? Anybody switched back to STOCK tranny tune?

The shifts will get better and better after a couple hundred miles. Although it will continue to have the shift points higher then stock.
After awhile you will notice how much better the shifts are firm and crisp over the stock tune.

Why do they have their Tranny Tune keep the TC from locking until 3rd or 4th gear??? Is that better for the tranny? And if your in 5th @ 35mph and let off for a bit it just drops to idle, wont stay engaged. I just dont get that. Im just nervous about it. I want Reliability...

I honestly think your tranny needs more time because its still learning. I believe mine will keep the tc locked in 5th until I drop below about 35 then it goes into 4th.

Best thing to do is the trans relearn get on an open stretch and do 0-80-0mph first at 25% throttle then at 50% then at 100% this will help the relearn process of the transmission learn to shift in fewer miles, but the transmission's in these truck are always learning based on driving style, it just helps it get a base faster.

1 2 will always be stiff at part throttle.

It's getting better. 1-2 is smoother.

What's the advantage of raising the shifts points?

I ran h&s tcm software for about a week and I wasn't to happy. It's was a little to performance oriented for my taste. I switched it back to stock. Overall 0-60 would be better with h&s but like the softer oem shifts.

I will give it a few more days. My driving consists of mostly 30-50mph. And when traffic slows/accelerates a bit I'm jumping in/out of gears like a semi.

Will the H&S Relearn be saved if I go back to OEM? Incase I switch back To H&S I won't have to go though this again?

I think the relearn is reset every time you switch from one to the other. Someone correct me if I'm wrong?
