a4ld symptom

[Momohenri]

Hello, news from my Bronco2, I put a rinse aid in my A4LD Ford box, and redo a new oil change. It's going a little better but I always have a problem, when I start the engine cold, I have to wait 1 or even 2 minutes before having a good push then it goes well even with a trailer of 2000 lbs. Weird symptom, when cold I start the engine, shift all gears leaving ten seconds as recommended to take the level, and the level is too high (as when stopped) I let it run and once the oil is hot level is good. This box has two solenoids, could it come from this or the pump or something else
