Same transmission, different vehicle.
Installed a DieselSite remote mount housing. Much bigger than the standard type. Has a large thread for the filter (BT839) and the inlet and outlets are large so fittings will be pricey to reduce down to 3/8 hose. Inbuilt bypass valve inside. All Billet aluminum. Beautiful piece.
I also installed a Derale pan but it wont fit due to the deep pan filter, need the short filter instead. Has an outlet fitting for a temp sender. I just mount the gauge under the bonnet with a switch for power. B&M and others make pans for the 4L60 as well.
Trans cooler - I bypassed the in tank cooler and went direct to a B&M Hi-tek fan cooler (large one). The fan very rarely turns on (normal city driving, no towing)
Fluid: Castrol Transmax Z
Hope this helps
