I reinstalled the 93 CAI tune, reset the TCM adaptives, and also had the tranny fluid & fliter changed (it was due anyway). The 3-2 downshift bump still happens but only with the Predator tune when in Autostick mode. The factory tune is still smooth. As noted above, it only happens as the car is ...

With the 93 octane CAI tune loaded (only one I've tried), I get a rough 3-2 downshift when in Autostick mode. This happens when I slow down and let the tranny decide when to downshift. If I make the shift myself then the transition is not as bad. The tranny downshifts smoothly in Drive mode. If I ...

I cant really explain all of that to you...but the 'shift firmness' is not line pressure at all, and things are not as they appear on the surface.... I get what you are "not " saying. After all, you don't want to give away all your secrets. That's how you guys make money.
One more question about ...

Who said it was in the FCM?
The '06 Charger service manual. Without changing the gear ratio, my car's tranny throws a P0733 code which is "Gear ratio error in 3rd". When that happens, the service manual says to check the pinion factor in the FCM to verify that it is set properly for the actual ...

I'm confused. If the tire size & axle ratio data is stored in the FCM, what is changing in the PCM to affect those parameters?

Which module is being updated by the Quick Adjust for axle ratio - ECM,TCM or FCM?
How about for the Shift Firmness?

Thanks.

I know that. That is why I am asking how the Dodge dealer can modify the ratio so it will be a "factory" setting.

Here's the deal. I have a 2006 Chgr R/T R&T that I swapped the rear end to one from an SRT (3.06 ratio). I will be selling this car but want to keep my Predator for use in the 2006 SRT I just bought! I need to reset the axle ratio in the R/T to 3.06 so the car's new owner doesn't need to rely on the ...

I don't know what menu options you have for the '09 fans but the 7135 menu for my '06 has 9 different settings that can be adjusted. There are fan setting for high MPH (above 15mph) and for low MPH (below 15mph). It sounds like your high mph HS fan is set for a low temperature value so as soon as ...

How about just asking your dealer?

They will know the gears have been changed.
They will know it won't run without pcm modifications.
The question is if they'll take issue with you running a modified PCM program/tune... my guess is probably.
Saying "but I only changed the gear ratio" isn't going ...

At 30% throttle, the temps climb.
I'm running a coolit fan mod, and the fans are coming on.

I'm curious - Why you are using the Cool It fan module when you have a Predator that can control the fans?

I haven't heard anything yet. Can you guys help?

I remember seeing 3.07 as a option in Predator. I belive this is the same as the AWD. Can the AWD ring and pinion be used in a RWD?
To answer your question - The AWD rear gears are smaller (198mm) than the RWD V8 gears (210mm and 215mm). The AWD housings are smaller since they are only designed to ...

That makes perfect sense.

I jumped from version 8r18 to 9r04 and easily noticed a decrease in the shift firmness. I've tried the quick adjust mode to increase the firmness more than once to make sure it programmed the change. It still feels more like the stock 1-2 shift. It is a quick two-step shift rather than the single ...
