So I take off from a dead stop, kind of quick in heavy traffic, but not peddle to the metal, and it shifts from 2ed to 3ed and goes boom. I let off and it seams ok. Give it some gas, and pull into the store that I was going to. Less then 1 block, but across a 4 lane road. I pull into the parking lot, put it into P, kill the engine, get out and look under the truck, all seams good, I go get my stuff, come out of the store, I look again, and all looks good. I fire up the truck, put it in R and it shifts, but nothing is there. No R. I push it back words, far enough to turn around, and put it into OD. All seams good. I pull out it shifts out of 1st into 2ed, all good then it goes to 3ed, and there is nothing there. Just to make sure, when I get home, about 1/4 mile away. When I get home, I always back into the drive way, so I try, but no R again. I jack up the truck after pushing it back words into the driveway. In OD its all good with the tires off the ground. I hit the brakes, and put it in R. The wheels start turning, bit seem slow. I grab a tire, and it stops turning, so I get my wife to hold that tire with the palm of her hands, while I go grad the other tire. I can stop it from turning. So I say let the tire go, I let mine go and crawl under the truck after I have my wife hold the brakes in R. I tell Her let off of the brake, and I put my hands on the drive shaft with he brakes off. I can stop it from spinning. Well I guess Im going to the trans shop tomorrow. Time for a reman.
