Tranny issue
My 05, f250, 6.0 has a quirky issue. Every morning it won't shift unless I let off the gas (diesel) first then it will up shift, let off the gas, next shift...after about a mile or two and any time for the rest of the day and night, smooth shifting without a hitch.
I don't dare pull out into oncoming traffic cuz the truck won't respond.
Any ideas as to what might be causing this?
Thanks,
Andre'

I bought the truck 7 months ago with 98,000 miles. At 100,000 I changed all fluids and filters so for me everything started at "0" miles if you will. I now have 107,000 miles. I know they didn't change the filter in the tranny pan but did change the filter under the front bumper. The one that looks like a toilet paper roll.

So...every car/truck ever built, you can start up first thing and drive away and Ford designs their trans to require a "warm up" before you drive off???? Oh, and the diesels shouldn't idel either...

i got a mazda car that does the same when the weather gets a bit cooler..
so maybe its fords and mazdas that build them like that..

My 5R100W has a paper filter inside the pan, yours may only have a screen but i'd still want to pull it to check things out. Checking the level of the fluid was a big deal according to the fluid change manual, took 2 people. Fluid type is also very importaint "SP". My trans shifts ok when it's cold but better when its warm. (think most transmissions are that way)

Mine does it year round. I do not notice any specific oil, coolant, or tranny temp that it correlates with. It just seems to be the first two gears, for a half mile or so. It feels a little like being in Tow/Haul.

There is something wrong. I don't know what it is, it will take some diagnostics and data collection to determine what's wrong.

Mine does this as well and always has when cold started for the first time of the day. Does not matter if its December or July . Letting truck warm up for a bit helps big time so I think Sandman with the thermostat comment is correct. After warm up its perfectly normal.

Yes, it has a thermostat. When the transmission is colder than 165F the cooler flow is reduced to 10% of normal. That's the only difference, less flow to the cooler.
