I have a '98 GMC K1500 with 75k. Truck runs great, but the transmission fluid has probably never been changed in it. I plan on dropping the pan for a filter change and get some fresh fluid in the old 4l60e. Im also doing a deep pan upgrade that'll add 2 qts of capacity.
Which fluid should I go with on an older 4l60e with low miles?
I believe the original manual calls for Dex III (Dex Iv), but have heard maxlife is great stuff as well that should be compatible.
Thoughts?
