I am rebuilding my 66 Mustang C-4 transmission. In rebuilding the valve body with a TransGo kit, my shop manual only indicates a small disc shaped check valve in the upper valve body. Previous Mustang Monthly articles indicate additional rubber covered ball checks. I was very careful when separating the two halves and only found the disc check valve exactly where the shop manual indicated. There were no ball checks. Also, the Transgo kit did not have any ball checks. Can anyone tell me if there any I could possibly have missed? Thanks.
