A 518 Seperating rear clutch, driving shell. UPDATE 1

https://board.moparts.org/ubbthreads/show...rue#Post5344236

From this previous thread, John Kunkel thinks I have an issue with the Belleville spring (Piston spring in ATSG manual.
Driving forward in Neutral and no Reverse is caused by a rear clutch that's not releasing, most common cause is a failed Belleville spring.

I have the trans out and disassymbled.

I can't remove the input shaft, rear clutch assymble from the Driving shell, Planetary gear train.

The ATSG mentions nothing about the seperation, and my 727 video shows them just coming apart.

~6" down the input shaft, there is a bearing surface and just below that is a ~snap/ round ring in a grove that has a dog leg on it. For the life of me I can't get it out. So I gave up and posted

Could it be that as John K stated, the rear clutch is hanging up and will not it allow it to seperate? With the output shaft in a hole in my bench, as I spin the driving shell, the rear clutch rotates in the opposite direction.....you can hear a slight drag of something in there.

Any ideas appreciated. Thanks

Most likely the clutch discs are hanging up, sometimes you can lift the transmission by the tailhousing and squarely slam it on the floor face down, the shock will usually dislodge them.

I've had some that wouldn't come apart, as a last resort I had to cut a hole in the driving shell to access the clutch pack snap ring.

The reverse rotation of the driving shell is normal.

John, how and what are they hanging up on?

I may make an Aluminum clamp around the input shaft and press down on the shell. I tried
holding the input shaft up off the bench and whacking the shell with a rubber mallet, and no luck.

What is the little round ring with dog leg I described?

Thanks 1000x for your help.!

that is for the clip that holds the input shaft into the rear piston retainer , taking it out will not help you get it apart, just the input shaft will come out and it won't just come out .

the rear clutches , steels and the bellvue are fried and probably welded together , I assume you have the front drum off ?

good luck , it's not going to be easy , I had a front and rear clutch stuck together , I ended up breaking the input shaft out of the retainer , at that point I just pitched the rest of it in the scrap pile .
