Stripped transmission gear pics

We don't often see this sort of damage, but someone managed to remove every single tooth from the main drive gear and about 7 or 8 teeth off the cluster gear. I don't think JB Weld is going to restore these............

I have. I kept the input shaft for a paperweight. Tell everyone it came out of a little ole ladys 40 ford.
 
That kind of carnage was fairly common back in the '50s and early '60s, when it was possible for "Randy Racer" to find a replacement trans in the junk yard for $5 or $10. DD
 
man, that must have been one hell of a power shift, ive seen a lot of cluster gears like that, matter of fact I did a few of those, but I never seen that many teeth off a main shaft, its a good clutch alignment tool now
 
your making me worried about using the 99a engine in my 33.even though its got the 46 gears.

my guess is the clutch was dropped at high rpms in low gear taking off a few teeth on the cluster gear, or a hard shift to second gear, then the broken teeth were pulled up to the main shaft gear by the oil, thus wedging the broken tooth in the gear and striping it, trans don't like odd bits of metal getting caught between the teeth on the main shaft and cluster gear
 
Now that's real talent. I've taken all the teeth off the second gear cluster but can't ever remember seeing anything quite like that. I don't think dental implants are going to help that one smile pretty again.
 
I'll take a guess: the broken teeth locked the cluster and the main kept spinning. A wonder the case isn't cracked.
 
Not even sure if we were told if the trans had any "issues" but we're expected to make it right again and that's what we'll do. I like Bruce's suggestion......sort of like tackling a 10,000 piece jigsaw puzzle. And I just showed you the big chunks......there was a lot of tiny pieces in there too.
 
Quite often that will happen on a one two shift when you try to make it sound like you have a Lenco.
 
I actually did that twice in my 50 ford truck in high school. The third trans I changed the bellhousing and had no more trouble. Must of had an alignment problem. Gary
 
This was a weekly occurance when I was young; it was a good thing Carmichel's Auto Parts in Excelsior, Minnesota was open until noon on Saturday; otherwise, we would have been begging for rides from our friends on Saturday night. We got really good at swapping transmissions and parts!
 
Back in the 50's me and my brother and a couple other guys swapped a junkyard trans into one of our cars every weekend.
5 or 10 bucks each.
 
Man, whatever the cause of this carnage is I want to make certain I never do it! I drive my car pretty hard, though I don't abuse it.
