C5 coupe harsh shifting question
I have a 2000 C5 coupe with automatic transmission. Of recent, the car shifts a bit harsh under moderate acceleration when the car is cold (ie sitting overnight). When the car warms up, it shifts very smooth. I took it to the dealer today, and was told that it is due to the damping mechanism going bad, either because of a valve or a spring located somewhere in the transmission. When the fluid is cold (more dense), it causes harsh shifting, but when it warms up, these parts perform as normal, and it shifts ok. I was also told it would cost about $400 in labor, and the parts have been discontinued that are needed to fix this. Does this make sense and where can I find the parts to get this fixed? I told the dealer to get part numbers so I can post them up. Transmission fluid level is normal, per mechanic.

OK, so after talking with the dealer again, I'm told that it is the accumulator piston and/or spring that is causing the issue (for the low price of $79 to get this knowledge). The spring has been discontinued, but there appear to be several aftermarket solutions. However, this gets pretty complicated fast and I'm very new to this.
Are other parts that are prone to failure (or are easy to improve) worth replacing while the transmission is out?
Just one example of the many options available from this manufacturer:

Should I get this for quicker shifting

and replace all the springs and pistons?
Also, what is a pinless piston?
I will be taking this to a transmission shop to install.
