E4OD slow to shift into OD?
Howdy all. I have a '93 F250 with a 351W and E4OD with 104k miles that I recently did a fluid and filter change on, probably a month ago and maybe 4k miles. In the last week it's been a little colder than normal here, read as being into the lower 40's at night (hey, it's Arizona), and for whatever reason the truck seems to not want to shift into OD the first time after starting driving. Typically it shifts about 45mph during normal acceleration, but that first shift it now holds around 2k RPM's and won't shift into OD for a few extra seconds.
I've checked the fluid level a handful of times in the last week and it's always the same, right where it should be, and there's no evidence of leakage.
The truck is used for occasional towing, and at least when I drive it I won't use OD when towing unless I'm at speed, 55 or better, on totally flat landscape with no hills in sight. Otherwise I have OD turned off, so I think I've been pretty nice to it.
This is the first truck I've had with the E4OD. The only other auto's I've owned have been AOD's and 4R70W's, so I'm not real familiar with troubles or quirks this tranny has if any. About the only thing I'm sure of about it is that they're not cheap to fix.
So what do y'all think?

I know on the 7.3L diesels, as part of the cold-weather strategy, the tranny shifts higher and stays out of OD... for a while, until the engine gets warmed up some. I have no idea if they do that on the gas engines too, but that's what it sounds like it's doing (i.e. totally normal.)
