Seriously, Cat's oil of choice was t0-2, then made it obsolete to their own equipment years later. Then the t0-4 superseded it and now, what trans-powertrain fluid can I use that will work just fine in the D4H that has a reasonable price, last owner said it was $700 to replace t0-2 fluid?
I pay about $60 per 5gals of to4
get the cat to-4 and change it yourself, a lot cheaper that way. If you use an off brand, its taking a risk with the transmission, and that cost big bucks $$$$.
