Truck had a fully loaded bed; after travelling 20 miles, I noticed that the transmission just stopped engaging. I coasted to a stop, worked an 8 hour shift, and tried to drive it home. I was able to get 10 miles before going up a hill caused me to glide to a stop again. Letting it sit for 20 minutes, I got it to go into gear, and travel about 1/2 mile. Then I had to have it towed home. I changed the filter, and two 'servos' that came with the filter kit. When I put it in drive, I could hear it and feel it engage, but wouldn't go in either direction. So, it sat last winter and summer. A couple of days ago, I unloaded the bed to take the weight out, started it up, and was able to drive it away for about 500 feet before I could feel it starting to slow. I adjusted the bands according to the book. It seems like something simple should fix this, since it occassionally works. Any help would be appreciated! Thansk!

 

The clutch packs are shot. It needs rebuilding or replacing. The torque converter also, don't think about flushing it. You'll flush all the money you just spent on the transmission.

 

When you drained the fluid was it red or brown? Smell burnt? Any debris in the bottom of the pan/magnet?
