I have a 90 XJ with 250K on it. 4.0 w/aw4. My question is that when i start it in the morning and take off it doesn't want to shift into 2nd until I let off the gas about 3000 RPM. After about 5 minutes or so after it warms up a little it shifts fine. I replaced all three solenoids in it and still the same. Also if I let it warm up in the A.M. before I take off it shifts fine! Any Ideas??? Thanks----Frencheey
