If you use H/D flex lines for trans cooler, i.e. change the steel pipe fittings in the box. Good time to change fitting ( swivel lock nut type ) when mounted to motor with a hose tail for alignment when not in car. If you use factory steel hard lines you may need to change the other end........
I'll be interested to see how the factory dip stick fits in the engine bay ( although I would remove it before fitting engine ) My trans came with a flaxie type one, still not fitted..................................
