update all fixed, I ended up re arranging the flow direction and went back through the radiator rather than bypassing it this is what I did as follows 1. trans line feed-top radiator-bottom radiator-top cooler-bottom cooler-return trans 2. added a 7' thermo fan fixed to the 14' trans cooler pushing air 3.. installed new gauge with needle. 4..changed from ATF DEX3-penrite semi synthetic. had tested at auto electrical for diagnosis trans everything working fine no codes and trans temp sits under 98'c. thanks for the input and help along the way. case closed.
