LOck up problems,chugging
LOck up problems,chugging My new 408 is runing okay I have the 4l60e with a TCI 3500 with stock 3.23 gears.Problem,when driving and trans goes into overdrive even third gear,only after the converter locks up I get this bad lock, unlock feel, its driving me nuts 
It doesnt stop doing it it kinda of like chuggs or something.I have to either press the accelerator or press the brake to make it stop Is this normal?,can I change TC apply table any or is this normal?

Lock/unlock indicates misfire events at a relatively
low level (not persistent enough to unlock it full
time but more like under a hard-coupled load and
lower RPM). You need to raise the isfire detection
threshold values until it quits showing misfires in
the areas that are hitting and unlocking, add a
little more for luck and tune drift, that should do
it. Though it's easier to just set all the tables to
32000 or so, that leaves you no misfire sensing
or "protection" (unlock converter during bad motor
jerk etc.).

Jimmy is correct. Ryan K posted a lock-unlock / random misfire thread a year or so ago. You can probably search to find it. I think he says to use 32574 or something like that. That's is what I entered. But you may just need to tweak your TCC tables to get your converter to not lock up until you really want it to. If you go to the HP Tuner repository jimmys tune or mine or several auto tunes should have tables you can reference.
