I was passing someone today after getting out of work. So, I pushed the pedal.. and the truck was trying to downshift.. however it felt like it hesetated, but it also felt like it was binding.. Kinda like it was preparing to lunge.. when it finally did downshit, the thing bucked, along with a popping sound, like the driveshaft slammed into place. What could cause this? It's happened once or twice before.. but a while ago...Any ideas? <A target="_blank" HREF=http://billybob.coloradok5.com>http://billybob.coloradok5.com</A> It's all fun 'n games, till someone gets stuck.
