I was thinking about flushing it but then I read that they are not such a good idea on high mileage transmissions or transmissions that you don't know the service history on. I don't know if the previous owners serviced the transmission or not. Also having 110,000 on it scared me. My dad flushed my moms 2000 SS at about 60,000 miles and almost immediately after we started having issues with the transmission shifting hard and the torque converter circuit being stuck on and the car jerks like crazy. The flush may of had nothing to do with it though but I am scared of them.

 

I'm on the "do not flush it" team. I would rather see you changer the filter and fluid every 15-20k than to knock something loose with a forced flush system.

 

This is for a homemade shift kit but still has disassembly & assembly instructions:
