I have a 97 automatic 4 door 4.0 AWD
On a recent highway trip, while disengaging from cruise control (not touching brakes), I heard a rasping noise from the driveline. Not grinding, but more like something spinning fast that wasn't quite engaged. Imagine the sound made when you run the shaft of a screwdriver along the length of one of those long flexible screw pick up tools with the magnet at the end - but a lot louder and faster.
I shifted into neutral (sound continued) and coasted to the shoulder, where the sound stopped when I got down to about 5 miles per hour. I stopped completely and put it back in drive... and seemed ok.
Continued on, 5 miles later, same thing happened. Shifted into neutral started to move to shoulder, but this time put it back in drive at about 40 mph. Sound continued and then heard a big BANG within a few seconds.
Got to shoulder. Truck wouldn't engage in any forward or reverse gears.
After a 4 hour flatbed ride, got the truck home. Now I'm trying to do some rudimentary diagnosis before I start pulling parts out.
Given the challenges with the transmissions in these vehicles, this is the obvious answer, but interested in your thoughts.
- Could it be something else?
- If transmission, does it sound rebuildable (the Bang tells me no)
Thoughts?
