    Flowmaster dual conversion

    Pretty substantial "rasp" factor. I wonder if that's because of the chambered mufflers.

    Transmission Only For Certain Years?

    FWIW, Ben, I usually go by car-part.com's interchange system for stuff like this. The bottom line seems to be that up to 2-5-07 is one part, and 2-6-07 and after is another. I'd suggest going by the build date on your car and matching it up with the appropriate date range. Luckily, the...

    Not Good Vibrations

    Not enough information to compute. Is it bone stock? Exhaust? Tune?

    What are you guys seeing for stock 1-2 shift points?

    Sure looks that way. I'm not sure they were engine harmonics though. If I had to guess, I would say that something in my dual exhaust was the culprit. The short version is, after replacing many parts in an effort to fix a really annoying driveline vibration at idle in Drive with the A/C on...

    What are you guys seeing for stock 1-2 shift points?

    Returning to stock tune resolved the problem, it shifted as you would expect, including light throttle upshifts at low RPM. Seems like increasing shift firmness with the Hypertech also cranked up the shift points, which is some pretty wonky behavior. I wanted an SCT tuner anyway to try to...

    What are you guys seeing for stock 1-2 shift points?

    Yep, I programmed it with a Hypertech Max Power. I enabled "increase shift firmness" (there's only an on/off toggle) and reduced the 1-2 shift RPM by 400. I didn't think that those settings could have that effect. The same programmer on my '09 F150 didn't behave that way at all. In fact I...

    What are you guys seeing for stock 1-2 shift points?

    Must be something wrong with mine. 1-2 comes in between 3500-5000 RPM most of the time. You really have to feather it to get it to shift 1-2 at much less than that. Anybody else?

    What are you guys seeing for stock 1-2 shift points?

    I'd like to hear from some other auto 4.0 owners as to what they're seeing for RPM on stock 1-2 upshifts. I just finished restoring an '08 V6 Premium, and it seems like it winds up crazy high before it pops 2nd. This is my first S197, and I'm just wondering if they're all like that. Light...

    Flat black dash touch-up tips?

    I'm finally coming down the home stretch restoring a 2008 Premium Coupe, but while cleaning some adhesive residue from the dash panel between the A/C vents, I used 70% alcohol and it stripped off some of the paint, which is a flat charcoal gray with weird sparkly bits in it. It looks terrible...
