[QUOTE="VH2K, post: 29574, member: 15488"] Usually I only drive it like 9km, or 5.5 miles, to and from work, and this never happens. It's only when the trans reaches operating temps. According to the needle in the dash this never exceedes mid-point (even when towing heavy-ish loads), i forget what that is, but like 90-ish degrees C, or 194 degrees F(reedom)? If I get a hold of a scanner, what codes would I be looking for? Is this car advanced enough so that it would remember what codes it was throwing yesterday, say? Do you know or have a list of codes that would be useful? (Me coming from VW and an OBD11 scanner which really functions great for DIY'ers) Again, thanks for the quick reply! [/QUOTE]
