Hi, my bossman has a 2000 dodge dakota with the 3.9 v6 with the 44r tranny. The truck only has 2 and 3rd. NO 1st and overdrive. I have replaced the 2 shift soliniods no fix. i have swapped out the relay no fix. anyone have any ideas what this could be. its throwing the p0753. then after clearing it with the scan tool it threw a p0743 then cleared again came back with the p0753. Can anyone help me out? it looks like a common problem in these trucks but no one seems to answer the questions?

Thanks Yall
Ryan
