I have a 44re that is acting up. I have adjusted both bands to factory spec, fully flushed with ATF+4 and put in a new filter. Symptoms: Delayed shift into reverse from park when cold. Slips on 2-3 shift under throttle, very delayed shift from 2-3 of I hard accelerate and then coast (shifts while coasting). While warming up the shifts from 2-3 will be delayed and hard, like I have a shift kit or something. When warm, the transmission will operate absolutely perfect. Butter smooth.
