Hello all. I posted a couple of months ago about changing the tranny fluid out for the first time (It may have been changed at 69,000 miles) at 180,000 miles. I ended up using Amsoil OTF doing 2 d&f about 500 miles in between. Ever since then (and it has been bitter cold since here in Chicago area) it is noticeably slower to go from park to drive or park to reverse until it warms up. Also it doesn't shift into second until a little higher rpm than it used to, again when its cold then fine after its warm. I'm thinking maybe this is due to it being a little higher viscosity fluid and the extreme cold temps? I thought about doing a 3rd d&f using Amsoil ATL. Any thoughts on that?
