Yep. Although I did have one issue, same thing happened in Death Valley, while driving up to Palomar on Nate's grade going about 15 miles per hour in 2WD in D after around 15 minutes the AT Oil light came on. I parked let it cool for five and then drive but this time kept in first for the slow crawl (my buddy is a slow poke). No issues this time as I kept the engine above 2500 RPM. I checked the fluid, nice and red and normal levels.
The thing is a similar thing happened in DV last year in similar conditions. My truck could have had this for a long time. I hardly ever drive slow up a hill in D 2WD for 20+ mins. I don't have the actual temps since it's a 97 but I understand the light isn't good.
Not a pink M. I changed the rad a few years ago with OEM and no milkshake.
I'm going to get it checked out next week.
