tranny question
I have had this 97 F350 for about two months now. This is that first auto i have had. The truck has 125000 miles on it. The tranny seems find. Sometimes when it sets all night and i get in it and take off it does not shift into overdrive until i go one or two miles. The fluid is full. I am the second owner and i don't know if the tranny has had anything done to it. I always let the truck idle for a few minutes before i leave the house. Plus i don't drive fast, my wife says i drive like a old man and i am only 24. The truck also has the 4:10 and 4x4. My buddy has a 95 F250 with a 5 speed and 3:55 two-wheel drive and he called my a liar that i got 19 mpg until he was with me one night i got fuel and then i got upper 18teens. I babied it that go around. I usually get about 17 if i drive it right and don't pull anything. well sorry for being long winded

I have the same experience with my E4OD. I would say it's normal. Just take it easy 'til everything gets warmed up.
As far as MPG, I drive like a bat outta hell everywhere I go, quick starts and stops. Just not very fuel minded. I get 17-18 MPG with the F-250 auto and high rear end. I get 13-14 with the F-350 5 speed and low rear end.

Stumpy .... I have the same thing going on. It was doing it before my tranny rebuild last month and still does it now.
Actually I believe it is not locking the converter instead of not shifting into OD. Any way I've noticed mine doesn't lock the conver till the temp gauge reaches just a bit over the cold mark. It does it the same everytime like clock work.
I would venture to say the computer isn't allowing the converter to lock to keep the RPM's up to decrease the warm-up time. Just my thinking.

Minor booboo on the temp, though. 135 was what the Ford shop told me back in '96 when I bought mine. I just took a trip across the river (10 mi) & watched the EOT closely. The converter locked up at 107 degees, per the Edge Evolution data monitor function. Maybe that's the Edge programming (at 80hp setting) or maybe Ford's all wet.
On edit...
Oops, I lied... It's the transmission oil temp that controls the t/c lockup. Either the Ford shop misinformed me or the memory bank found a flat spot. Since I wasn't watching the TOT as closely, I'm guessing that it was somewhere in the 80 degree area when the converter kicked in.
