I'm having a quirk/issue with trans torque management on the P59 controller in my 2006 Silverado. The calibration/OS is 12619623. The issue I have is that if I run some torque management to try and help the trans shift quick and safe, the torque reduction lasts too long at part throttle. It is highly unlike Gen 4 stuff where the timing pull is near instant and is put back near instant. In my case, when the PCM commanded the shift, the timing did pull near instantly just before the shift, however it took 1-2 seconds after shift completion for the timing to come back in. It wasnt a slow ramp in, it comes back all at once, it just took too long to come back in. It literally feels like a 50 shot of nitrous coming on a second or two after the shift. And while it?s under tm, the exhaust note is burble/misfire obviously from the retarded timing. At wot the timing pull is out and back in instantly. Like it should be! Matter of fact, my scanner didn?t even pick the timing drop up, but it?s undoubtedly there. I'm not seeing any table in my tune to shorten the length of torque reduction on the shifts. I'm attaching a copy of my tune with all of the torque management, shift time and pressure tables set back to stock. I'm open to any suggestions and help. Perhaps my OS is missing a table?
