A couple of months ago I was towing north on 180 over the Guadalupe mountains towards Carlsbad. There is one spot that I was forced to slow way down for a turn then it gets very steep right out of the turn. As I started to climb my speed started to drop so I added more pedal. Speed kept dropping until I had the pedal on the floor and it would not downshift. I ended dropping the shifter from 4 to 3 and it finally downshifted but by then I was down to about 20 mph and just crept over the top. Since then have been over lots of steep grades and it has not done it again. Funny thing is my Blazer did the same thing to me years ago and I was not towing. That time I thought I had blown up an engine but when I got over the top it ran fine and never did it again. For the life of me I cannot figure out what driving conditions cause it.
