I've been reading this thread, and I think you will probably be the person that I should talk to; although anyone with info will be a saviour as far as I'm concerned. I have an 02 Passat, with the Tiptronic. As perplexing as this has been for me, I still have no solution in sight.
Regular automatic mode:
1. As the trans shifts from second to third while putting around, it almost feels as if the trans is shifting into third, and then directly into fourth. I know this is not happening, because I count the gears that follow, and sure enough, there are in fact 2 more after the above scenario.
2. While using the "passing gear" from fourth, say in a traffic situation, the trans shifts from fourth to third, and just about every time it does this while on the gas, it feels as it slips and then catches. All the while, it does feel like it's pulling, but doesn't feel just right. It feels like when I let off the gas, it almost improves the "drive" of the transmission, and makes it easier for the trans to engage in the gear.
(Leads me to believe the clutch packs are slipping)
1. Drive the car sporty, in tiptronic mode, first to second, when second shifts, it's just like the "automatic mode" scenario, only in second. Feels like the trans shifts, but then shifts into third imediately. We know this isn't the case, because it is in a manual shifting mode. I'm scratching my head. It won't do it in any other gear while in tiptronic mode, and if I downshift while in this mode, all is good.
(Can you understand my dilema?)
Don I would love for you to help me understand this problem before my warranty runs out, and point me in the right direction. For that matter, anyone with some helpfull guidance would be a saint.
