thanks for the advise bro.
Guess ill invest in a new or used Driveline, I had already replaced the U-Joints, infact there not even a month old, the yokes could be one of the problems. Thinking back about 1 1/2 weeks ago I took along drive out site seeing with the truck, I live in the desert and there's alot of hills/mountains. After that long drive is when the Slipping began to start. I took it for a short drive today just cause I love driving trucks, its slipping in just about any gear.
The good news is that I can buy a used tranny for $166 bucks at PIC A Part in las vegas. So Ill pick me up one with in afew weeks, along with a driveline.
Thanks again.
