Took the car out this afternoon for a highway drive and everything was fine until the car warmed up. Then it started having trouble with the 3-4 upshift, so I got off the highway. After stopping at the light and getting going the 1-2 shift slammed into gear and I checked my Aeroforce. Sure enough it popped a p1811. I limped the car home and it only had two hiccups on shifting in the 15 miles it took get home. I'll be limping it to the dealer Monday morning for a better diagnosis, but I'm speculating that I'm experiencing a PCS issue of some sort.... thoughts?
