I'm planning to install mine this weekend (if I feel well enough). I ordered some spring action hose clamps from Toyota to link to the OEM transmission return line (those arrive on Monday this week). The Toyota camps are Not required, but I wanted to match the style in the engine compartment to make it easier in case I need to stop using the external cooler for any reason. I also picked up some Toyota WS ATF last Friday. I ordered an inexpense hose pump to make it easier to top the transmission off.
