24vromaniuk

Hello, first post on here hoping I can figure out my issues with my 98 24v cummins, occasionally my truck upon start up with stick in either 2 or 3rd gear not sure which one upon putting it in drive, truck will not upshift or downshift until I put it in park turn it off then restart the truck then it will be fine start first gear shift through all the gears and go into overdrive, I pulled 2 codes scanning it with my tuner, P0753, P0748 AND P0743 this problem comes and goes but it always resolved with turning the truck off and restarting making me lean towards and electrical program rather than hardware issue, if anyone can help fix this greatly appreciated!!
