Sajeev,

Long time listener, first-time caller. I’m responding to your plea for new Piston Slap questions. I purchased a gently-used 2008 GMC Yukon Denali AWD a couple of months ago. Other than its appetite for fuel, the only negative is that it has 141,000 miles. I believe the previous owner changed the transmission fluid at 100,000 miles (Carfax shows that the transfer case fluid was changed at this point, and I can’t imagine doing that and not doing the transmission). The fluid was relatively clean but I changed out several quarts via the dipstick tube using a fluid extractor after I purchased the vehicle, replacing them with the specified Dexron-VI. I believe the fluid level is correct but it’s difficult to read.

On a recent road trip, the 6-speed automatic (6L80E) transmission stumbled during the 2-3 shift while driving through the mountains and went into a failsafe mode. The check engine light came on. I pulled over, turned the ignition off and on again, and the truck operated normally. The CEL remained on for the next several ignition cycles. When I called OnStar to obtain the fault code, they could not retrieve it because the CEL was no longer on.

As I gear up for NAIAS (read: do laundry, look for my passport), I am scanning the schedule for what press conferences are worth going to and what’s worth skipping? If you have any special requests, speak now in the comments or forever hold you peace. Personally, I’m most looking forward to seeing the new GM full-size trucks. I liked the old GMT900 pickups, but the bar has been moved forward consecutively by both Ford and Ram. The old formula of a simple, honest no-frills truck may not be enough – and that could be a disastrous miscalculation by GM, leading to a Civic/Malibu-esque need for a mid-cycle refresh.
