    Any other 392 peeps feel a sloppy shift from 4-5? Usually 1/2-3/4 throttle. Hellcat peeps chime in if you have noticed anything with your A8's.

    I would not call anything my A8 has done sloppy.

    I notice it in Default mode whilst manual shifting. Always 4-5 shift. Everything else is nice and tidy.

    Tough, to compare, not apples to apples, over 200 ft-lb difference in our automobiles. Also, you do not have the same exact tranny as we do.

    I saw that they aren't the same, but they do have similarities. I just wanted to get a feel for whether this is isolated or common before I take it to the shop.

    My SRT A8 shifts perfectly. I'm still impressed with how this tranny performs.

    What mode is the transmission in. Have you put it in the different modes to see the diff.?

    Most noticable in default, but I can still sense it in Sport, but not nearly as much.

    So I made it into the shop today. I wasn't expecting much, but was surprised that there was a code hiding. No CEL, and no MIL. It was P1DC8-00 Clutch Temp Threshold Achieved Autostick Inhibit.

    According to the printout, possible causes include:
    Excessive amount of WOT driving, or
    Excessive amount of paddle shift usage in low gears.

    I have only made one WOT run and it was up to 60mph, and I don't use the paddles much. I think there are more causes for this code, and my original issue.

    So the "fix" this time around was resetting the TCM. I'll give it some time to learn before I decide on if it is fixed.

    Huh? They have to be kidding? Excessive WOT!

    Tell me you were pounding the paddles.

    I too have noticed a slower shift from 4th to 5th under a part throttle application in Sport mode only. She shifts fine in Street, Track, and when using the paddle shifters. She has 2,684 miles, and has only *1* W.O.T. run to her credit. She did have a P.C.M. and T.C.M. update in May at 609 miles.

    I notice it in Street...still. I also only had 1 WOT, and under 2k miles. Maybe I can get it on a dyno soon so I can see if it is noticeable wide open.

    This is exactly the same problem I've been having as well. Mine dies it in street and sport, but it acts differently in each mode. What's the process for resetting the TCM? Is that pulling the battery for some length of time?
