HDJ81 Transmission cooler inlet/outlet?

[fvaleur]

Hi, can anyone tell me which of the lines going into the bottom of the radiator on my 1991 HDJ81, with A442F tranny is the inlet, and which is the outlet?

Also, how do i see if the transmission is electronic or fully hydraulic? It's from 08/1991, in case that makes a difference.

Thanks!

No, not necessarily. No solenoids on my 1991 HDJ81 with the A442F.

When I added my aux tranny cooler I removed the 12v wire to my IP and removed the 2 rubber lines going to my radiator cooler and turned over the truck to find out which was supply and return

Looks like you would have the full hydraulic tranny
