If you're going to look at any type of data (DRB or other scanner)...which
would be helpful...don't set anything back to stock just yet. Get the data
and then put it back. However, this leaves you with another
dilemma...returning it to stock will either clear out the PCM's adaptive
memory ("chip" programmer) or will distort the actual adaptives left in
memory (removing a "chip").
That is one of the signs of a converter going out...but not necessarily the
problem at hand. Without looking at the PCM data, it's hard to say what it
is wihout just guessing.

Subject: DML: Stalling 4.7L, auto
Lately with my 2000 4.7L auto with 98,200 miles, when stopping the truck
will stall. Not all the time but about one time out of say 30 times. It seem
that the tranny dose not want to come out of gear and stalls the engine.
I've also noticed that the engine is pulling harder on the tranny when this
happens, guess its just trying to keep up the RPMs. Sometime it wouldn't
stall but the engine is still pulling harder. I did do a TransGO shift kit
to the tranny about 4K miles ago. Also have a SuperTuner Chip installed, The
stalling was taken place when it was set to the "towing" and the "87
octane". I haven't returned it to stock yet, I'll do that this morning and
see what happens. No other work was done to the engine shortly before the
stalling started. ATF and filters have been changed at 40K, 70K and at 9540
miles. Any thoughts?
I hate to ask, what are the signs that the torque converter is on its way
out?
