Pulled all the old transmission cooler lines and the external cooler... went back to stock routing and cleaned up the corner of the engine bay where the cooler had been mounted. Also pulled the plastic catch can and went to a smaller, stainless can.
Installed the new cooler lines (shout out to Inlinetube) Having them run as original is allowing the speedometer, shift and park cables to also run correctly without a lot of bending.
Got the new speedometer cable installed going from a 17 to a 21 tooth gear. Should get me closer to actual speed indicated.
