TSB question

[Chump]

Component Description:
1. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM, PCM) Bulletin Number: 04032007
Bulletin Date: Apr 07

Vehicle: 2006 Ford Mustang
Summary:
REFLASHING THE POWERTRAIN CONTROL MODULE (PCM). ( NHTSA ITEM NUMBER - 10021732 )



Anyone know what this pertains to? or what it is?
My trans seems to be slipping a bit in 4th gear, I thought it was just hitting overdrive early and kicking right back out but after turning the OD off its still doing it under hard or medium steady acceleration

Please do not have this procedure done with out first removing our tune, then it may not even reinstall depending on what PCM code they flash it for. If its matching to the one we wrote the tune for it will work, but if its a different code then you need to get a new tune from us.

Its still doing this even with our tune in it?

Ya I talked to you earlier today which you informed me about the stall lockup that was in your tune, which now it makes sense to me. Thanks!!

I had my father double check your tune for the lock up and its on a 2 sec delay before it locks up in fourth giving you that extra "bump" right after the 3-4 shift. Actually this will help alot at the track, especially when you get those pulleys on!!!
Yep glad we figured it out together before you went the the dealer!
