Transmission fell out of engine while driving .

Aye Carumba! In all my years, I don't think I've ever seen a transmission fall out. I always used thread sealant on ALL bolts. I think someone who did the work has some 'splanin' to do,,,

 

I''ve been around trucks for 45+ years .. never heard of a transmission falling out either.. untill about 4 years ago .. have a neighbor with a FLD have one fall completely out cause massive Carnage and made its way under the front hopper of his welfare wagon and tear a hole in the trap..
I seen it with my own eyes
It must be a Frieghtliner thing ..Lmao

 

Believe it or not, I've seen many trannys fall out, or near fall out.

Yes, always has been the fault of bad repair. Doubt you'll get the dealer to agree.

Bad thing is, you should have noticed it, at least a symptom, like a vibration. They usually don't just fall out. Top bell housing bolts loosen, tranny starts tilting, eventually to the point of all bell housing bolts break and trans falls.

I could see it would be harder on an auto though to notice a coming failure. On a manual, driver notices clutch free play getting wonky, and definite noises and vibrations as the input shaft and clutch get crazy.

Did have a USA Truck driver way back though say there were no symptoms till the stick fell through the floor.

He was FOS

 

SAY WHAT !!!!!! a trucker driver FOS you say ??? I find that hard to belive !!!!!!!!

 

I had one happen on a pete.
New clutch, ran it for 3 months, noticed vibration.
got underneath and they’d stripped out the top most bolts and transmission was leaning down.
called a wrecker, towed to shop, they wouldn’t make it right, but would fix it, I then eased it a few miles to a kw shop, paid their price vs the other guy that did all my work like that.
Cost me another new clutch and a 13 speed transmission.

 

Likely the bolts weren't properly tightened during the repair.

Its been 8-9 months since the work was done, it'll be very hard to pin anything on them because it could have easily been prevented had somebody crawled under the truck now and then to look things over (which should be done regularly).

 

Yup

 

More than likely. Good chance there could be flywheel housing damage and driveline damage as well.
