SRT8 Jeep Extreme Automatics NAG1/A580 Neutral Hunting/ Coming out of gear
Howdy Everyone,
I have an Extreme Automatics Built A580/NAG1/722.6 (whatever you want to call it) :p and i'm about out of ideas here.
2013 SRT8 Jeep
Built 6.4
RIPP Supercharger
Extreme Automatics Built A580
3800 RPM Stall
670whp 640wtq Dynojet
I have tuned another truck at much less power with the same exact transmission and have not experienced these issues.
Basically, after doing a WOT pull (Call it a 2nd to 3rd pull) and letting off the throttle, the truck will go into neutral, and throttle will be dampened significantly, almost like a limp mode. Once you get below about 20mph the transmission will find a gear and continue driving. It will throw code P0733, described as Gear 3 Incorrect Ratio.
The transmission was sent into EA and Lonnie (who is a fantastic guy BTW) went over everything. We couldn't find anything wrong with it. Aide from this issue the transmission shifts fine.
What I've tried with NO change:
Running the stock TCM file
Running my Cal file from the working truck
Performing a dealer update on the TCM to address anything background that we cannot see on HPT
Raised allowable shift times in the Cal
Playing with all torque limits in the Cal
Disabling the P0733 code
Manually shifting the truck on both Cal files
Cleaning valve body solenoids
Adding and removing TQ Management
I'm looking for someone who experienced this. Lonnie at EA said they've seen it once, but that it would not occur in manual mode, which is not my experience.
