2008 Ram 1500 Quad Cab 5.7L 4x4 (1/2 ton, NOT MegaCab). Diablesport InTune I1000
During moderate to heavy throttle I get a ratcheting noise during the 1-2 shift. It does not happen during WOT. It only happens when a tune is installed; any tune including MPG boost. I can not duplicate when there is no tune installed. It sounds similar to a spark knock but only happens during the shift; nothing before or after. I installed a K&N CAI and a Dynomax cat back and nothing changed. Any guesses?

I was able to record 3 pulls this morning. How do I read the logs?

Re: Knocking during 1-2 shift.
So this happens when shifting at part throttle?

dodge doesnt play the +/- game
If there is KR on a dodge, it means something bad happened and the pcm is pulling timing as a result

Re: Knocking during 1-2 shift.
OK, here's 2 logs. On the "00" log I duplicate the issue 3 times back to back; 1/2-3/4 throttle, 1-2 shift. To me, it SOUNDS like a noisy trans solenoid (like a Chrysler 604 or 42LE), but I cannot duplicate it with a stock tune. It only happens DURING the shift. This is the 87 octane tune with 87 pump gas.
On the "01" log I did WOT 0-90 mph; I did not hear anything there.

Re: Knocking during 1-2 shift.
there is some ST knock at the shifts. Thats not entirely uncommon when shifting. Can you log the stock tune as well in the same conditions?
