I'm trying to get a little less engine braking when I'm in DFCO. On the hwy when DFCO starts in 4th, if I tap the brake, I can feel the TCC unlock, and I can see on the scan that the rpm's dropoff rather quick, and less engine brake. Shouldn't the TCC unlock on decel? I'm running the ARAP $6E, and coast release is set to 32mph. Does this mean that above 32, it will release? Also, what is the coast load limit? currently is at 3.13 % tps Also, it's hard to keep the car from lurching forward when DFCO ends. Thanks for any help.

Not sure how much of a difference it will make unlocking the TCC is 4th gear. The 700R4 doesn't apply the overrun clutches in 4th, so minimal engine braking will occur. I played with keeping the TCC locked during coast and felt no difference while in 4th gear.

Now in 3rd gear there was major difference. Felt like a stick car as the overrun clutches were applied and the TCC was locked.

The 32 MPH setting is a threhold to select between two different coast unlock TPS% settings. More info in these threads:
