Here's the scoop: original trans rebuilt by a reputable shop at about 230k miles and now I have to go find my warranty paperwork. Truck has almost 250k miles about four or five years later.
I was going down my long driveway a bit ago, barely into throttle, under ten miles an hour, when I heard and felt a CLUNK and had no more forward gears. Shift to reverse, no reverse gear. No 4wd. Tried to put in park and had what I would call a light grinding. No leaks, no previous issues, no previous noises to report that I recall.
Mayhap it is something simple. It's down my driveway and I plan to get under it and see if somehow the bolts came out after years and the whole housing backed off or something weird. Hopefully Mark sees this soon before I have to talk to my wife about it BAHAHAHAH!
Put the transmission in PARK, parking brake off, wheels (very loosely, a foot or so) chocked, and see if the truck will roll or not. If it rolls, your transfer case busted internally. If it didn't roll (parking pawl successfully engaged and holding drivetrain), then something internal to the transmission broke.
So here is what I found when I got under the truck. Found this in the driveway, but no clue if it came out of my rig. I have five bolts left
I spent the afternoon mating the trans and transfer case back together. I don't move as quickly as I used to. Noticed some cracks on the rear of the front driveshaft ears, too. Then I carefully backed it up the driveway and into its spot. Didn't notice any odd noises in the couple hundred or so feet trip of twisty turns up and down hills, so that's good, I hope.
I plan to have a flatbed take it to a shop this week. BAH!
that looks like an alignment pin that snapped out of there, definitely sounds like the transfer case might have an issue.
I was going to say torque converter until you posted that picture. Its almost like the gears or a drive shaft jammed somewhere and caused the case to rip or shear itself off when the energy had no-where to go.
I agree that the object pictured appears to be one of the two alignment pins that reside between the bolts. Not enough info in the pics to see what might have happened to cause the case to separate from the transmission. Could be a faulty install...Never heard of one coming loose without serious trauma to it.
You say you have 5 bolts left, I'm guessing all the bolts worked their way loose and you are left with just 5? As in the previous shop didn't torque/tighten things?
