Yea, the trans slips going into 3rd, itll even cause a loss of speed, have to be doing about 50 before it'll shift(when getting on the highway) or idling when going down a hill. i can also move the drive shaft at the end of the tail housing and the u joints are good and tight. All in all, its a good truck, paid $400 for it just over a month ago and am using it as a daily driver. the only thing i have done to it is rebuild the carb (fuel leak at accelerator pump) and replaced the radius arm bushings, and built a custom center console. thats it. The funniest thing i have ever heard is when i was out in va beach when i was in the military and i went up to DC to visit a friend of mine and they wondered what a cow was, never seen one, thought they only existed in zoos, no kidding.
it looks as though my tires should be 235/75R15 instead of 225/75R15, that wouldnt cause a 10mph difference at 60 (spedo shows 50) one wouldn't think

Man you gotta love those $400 trucks! Funny thing is my speedo didnt change when I went from 235/75's to my 32x11.5's. Of course not too much later my speedo quit working alltogether. Maybe that had more to do with it.
