When in select shift manual the ratio off engine rpm to car speed should be constant in a given gear unless there is slippage. There can be slippage with slippery roads, of course, but if the roads and conditions are good the only explanation for slippage is the clutches are slipping. And no, that is NOT how they supposed to work except during the take-off from a stop. If you're cruising along at, say, 55mph in 6th the rpm should be about 2060 give or take a bit so if it's sitting at, say 2060 rpm and then you hit a hill that puts more load on the car and the rpm increases even though the cars speed stays the same or decreases there can be but one explanation -- clutch slippage!
Really folks, if you are having this DCT problem it would be a very good idea to either buy an OBDII dongle or borrow one so that you can record data and show them. If that doesn't work perhaps you could contact a lawyer and I can pretty much guarantee that if the dealership receives a certified letter on a lawyers letterhead that references this data the dealer will not easily ignore that!
So your post confuses me. When cruising at let's say 55mph and 2,000 rpm And you start going up even the slightest incline or hill your rpms will go up. You are saying because of clutch slippage, but isn't it technically going to have to raise the rpms to stay at 55 mph because the car will need more torque to overcome the incline at the same speed?
its like walking up hill. You need more effort (rpm per say) to keep climbing the hill at the same speed.
I'm just confused as to why this is clutch slippage.
