    Transmission skipping.

    Guy at the dealer said that there is a mechanism in the transmission that keeps it from skipping.

    Does that sound right?

    Like that old feeling when a clutch slips on a manual transmission. I'm not sure I'm feeling something like that, but I've seen transmissions that lag between gears, and the harder you press on the accelerator, the more it will slip.

    Re: Transmission skipping.

    It sounds like he's talking about a torque converter lock-up shift.

    Sounds like someone's rising the clutch between first and second gear.

    Do you mean riding the clutch?

    Re: Transmission skipping.

    Your transmission is slipping between 1st and 2nd gear?

    That's what it seems like, although very little. It's like, when I'm driving, before the car slips into second gear, I can feel the rpm's raise just a little bit before it drops into second year. This might even be normal.

    Re: Transmission skipping.

    It may need an updated TCM program. Cadillac released many programs trying to address different issues. Some correct harsh shifts; for those that prefer them silky smooth? What clutch wear can be expected?

    Others prefer quick, positive shifts, even if a bit intrusive. Next, define a curve to that spectrum based on throttle position. Finally, after the real world experience of buyer feedback and warranty service claims, adjust the programming to please the majority.

    It's worth a shot. If you're without a warranty, a transmission repair can be daunting.

    Re: Transmission skipping.

    By the way I have this same issue when going from 3 to 4th. I have a thread open about it in the v forum. It's been identified as "shift flare." There's one other guy who has it but from 1 to 2 I think. E chase 3's recommendation about the update is my first step.

    Re: Transmission skipping.

    Keep in mind that the TCM adapts to your driving habits and learns as you go. A good start might be to do the old battery disconnect trick which will reset the adaption process to original. If it goes away you'll know it's learned behavior.

    Re: Transmission skipping.

    Yes good point. That was the first thing that was recommended and I already did that and no dice. Problem still existed but that advice is right in line with what fellow v members advised.

    ----------

    So maybe it's not the tcm thing after all. Might actually be a mechanical issue. Ill eventually get to the bottom of it. Fun part is it's intermittent so showing the problem to the service guys will be tons of fun. And they'll think they fixed it, drive it, won't get the flare, give it back, charge me and the next day it'll happen again. It's gonna be a fun one. Well the powertrain warranty is still in so I guess they won't charge me.

    ----------

    Or they'll somehow relate it to my headlight and charge me because headlights aren't covered in the powertrain! That's a shout out to you rnkath08! I feel for you.

    Now it's starting to skip from 3 to 5 when not feeding it much. Sound like it'll jump from 3 to 5, then remember that it skipped 4 and go back and get it. But if I take off faster, it'll shift normal.

    And when I shift from D to R to back up, it takes about 3 seconds for it to get in gear.
