Automatic Trans Rebuild Expert Advise Needed
While disassembling my THM350 for a total rebuild and by following the Haynes Techbook, I found the following problem, (if you have the Haynes Book it is step 8b.22 thru 8b.24) after removing the 2-3 accumulator piston I found the spring underneath was broke in three pieces. The bottom of the piston is gnarled up and I am sure needs replaced. The piston did not come out of its cylinder easily. It almost feels like there is a slight lip at the top of the cylinder. Can you tell me what I should do? Do I need a whole new valve body? Can I just get a new spring and piston and clean the bore up with Emory cloth? What else do you think I am in for or should look for?
Just curious as to what would have broke the spring like that. Seems like a fairly heavy spring.
Thanks In advance for any advice.

Thanks Steve,
I was not able to drive this car when I bought it and was wondering what would the previous owner experience in the performance? Would he have known there was something not right with the transmission, shifting hard/soft?
I completely disassemble the transmission yesterday and noticed that ALL the clutch plates looked fairly new for a car that is supposed to have 120,000 miles on it. I am wondering if they realized that there was a problem and just rebuilt the core of the trans and didn't bother with the valve body.
Thanks again
