The other day, I was getting on the highway and when I stepped on the gas, it was like as if the gears didn't catch, or something, because the rpm's went up and down real quick and I wasn't gaining any speed!!. Does that make sense?? I just got my VX lifted 3 in. and I have 285/75/16, BFGoodrich A/T KO'S. Does anybody know if the lift and heavier tires might be causing this problem with my tranny?? My VX only has 8,000 miles on it. And is only serviced by Isuzu. I'm perplexed! ya know?!
