My KR has 60k miles on it, I bought it used with 55k miles and tonight on the way home I was merging onto the highway and accelerated. When I accelerated the truck stuttered and the trans. light started blinking, I put it in neutral and let is coast after a few mins the light went off and I drove it home slowly. I checked the fluid when I got home and it looks clean and at the right level. So I did a search on this forum and a lot of topics point to spark plugs and fuel filters but none of those threads mentioned their light coming on.
