Thanks for your replies. I have changes the fluid/filter twice now. Once at 60KM and once at 120km. I have experienced the hard shift two times now. Once before the last fluid change and once after (the last time was after being stuck in stop and go traffic for a while and the engine temp gage was at 3/4. I have since been stuck in the stop and go traffic with the seafoam additive and have not noticed the problem yet, more time is needed).
The stored code was for the PCS (1811? I can't remember the number) I have heard that an external trans cooler will help keep the transmission cool enough to help with the problem. What are your thoughts about the extra cooler?
Thanks,
Mark
