Thanks, Dpea - I kinda figured that'd be the reply, but it's good to hear it. I've been adding ATF with about every other tank - should I add it to every tank, when the temperatures drop?
When I drove t/t, it was a company truck, maintenance wasn't my concern, (other than getting it to a shop), so a lot of this is new to me. Sure wish I had an owners' manual, sigh.
