Getting close to 60k miles and I am planning on doing a transmission service. Replace filter and pump all old fluid out and replace with new.

I want to disconnect the return line to the radiator and attach a hose to have the truck itself pump out the old fluid by turning it on for a few seconds.

Im not 100% sure but is this the tool I need?

3/8" Jiffy-tite Disconnect, Low Profile
