man i junked my 88 2wd A43D trans truck last april it always worked great hmm
i did notice thoguh that it wouldnt go into OD until it was at a certain temp
if it was too cold then it stayed out of OD automatically for a while no matter how fast i tried to get it up to
on warm days it always went right into OD at required speed somewhere around 40 miles per hour or so
temp sensor/ECM issue on yours maybe
if the bad solenoid is ruled out
or wiring plug connection corrosion or loose-ness, etc
if these solenoids use any rubber seal or any kind maybe some trans fluid seal conditioner additive may help ?
always is nice to put in higher mileage trannies before its too late and seals go bad due to age and heat
good luck
