Yesterday on a 2-3 shift at wot I lost all forward gears and reverse. It has all the same symptoms as the time I broke the input shaft on a 2-3 shift but didn't make the loud bang when it broke.It now has a 300m input shaft.
When we got the trans out today the input shaft spins easy like when I broke the stock one but its different. This time it doesn't feel broken like before. You can feel that the splines are stripped out.
My guess its not the shaft splines but the splines on what it slides in? BIG? What is this part?
The pan had nothing in it to worry about.

The input turbine shaft goes through the overrun clutch housing assembly. It connects to the overdrive planet pinion gear. It is possible to break the pinion but I am thinking maybe the overrun drum and roller clutch are damaged, or the shaft broke.
I am no expert though.

Thanks for the info.
This is a FLT lvl 4 with a 300m input shaft. It has maybe 5000 miles on it.
I've watched some videos on 80e disassembly and it doesn't seem to hard to get this assembly out so I can see what happened. Is there anything really difficult about getting this part out?
