I have an 03 Chevy 2500hd with the 6.0L, the bottom transmission line popped off on me and naturally blew out all the fluid, I was going under 10mph and only went 1/4 to Half a mile. When it popped off I was in 4wd in some crusted snow, I pinned it to get out and that's when the line popped. Luckily I was at a neighbors farm yard and found tranny fluid. I filled the tranny and it would go forward, but no reverse. I was able to drive home, no cell service for a ride home. Drove about 10-15mph, trans temp was "normal". When I put it in neutral now, it goes forward, tries to stall in reverse and will not go into neutral. This is the first and only issue I've ever had with the pickup. Maybe the bands or the clutch's are bad, or gummed up solenoids, any advice would be greatly appreciated.
