Default Can't get Converter to lock. Please help.

I just reprogrammed for new gears (from 3.23s to 4.10s). The shifts are fine but the converter won't lock in 3rd gear. This is a big problem because unlocked, I run out of rpms around 93 or 94 mph. Unless I want to run the 1/8 mile from now on.

Right now here is how I have it:

1-2 Shift @ 30 mph
2-3 Shift @ 60 mph
3-4 Shift @ 121 mph

2nd: apply at 54, release at 50.
3rd: apply at 74, release at 53.
4th: apply at 110, release at 90.

It should lock at 74 mph in 3rd gear, right?

I am confused, why you having it lock at such a high MPH?

If anything, 74 mph is low. The only reason it is so low is because I have 4.10 gears. With 3.23s I had it locking at 95 mph and I was running 11.7s @ 114 mph with bolt ons. Are we thinking about the same tables?

Ahhh, that makes more sense. Which table are you modifying?

The TCC mph threshold.

I think you just made me realize what the problem is. I have to change those values in those other tables also, don't I? All six of them, though? Also, allow TCC to lock during shift should equal false, correct?

I think you should only need to modify the Normal Mode MPH vs % TPS.
