I rebuilt my TH350 last summer, I was a little intimidated at first, but once I got into it it was actually pretty simple. I completly disassemble it and took the torque converter and a few parts to a local shop. I had them flush the converter and run the case through their machine to clean it. Then I had them install any bearings that needed replacing. I assembled the rest. I bought my kit from Northern auto along with a shift kit. I cannot stress enough that a good manual and torque wrench are needed during the process. I took a bunch of pictures, but don't know where I have them.
