Trans problem

Hello hopefully some one out there can help me a little with this. I have a 2000 f250 with a 7.3 and the 4R100 trans. It seems to be working fine in drive as long as the overdrive button is on but will barely move in Reverse, 1st or second feels the the brakes are on and if I give it to much throttle the trans slips. If I shut the overdrive off it also does this in drive. Was getting codes P0715 and P0717 so changed the TSS sensor but still kept getting codes. Now today not getting the codes anymore. Wondering if maybe it is an electrical problem since drive works OK until I shut off the overdrive. This trans has been rebuilt 3 times and has about 75000 km on this rebuild.

Their quite high some times. Will stay around 180f driving around town with no hills and just came back from work yesterday 200km and would reach as high as 225f if there were any hills but drop to 180 to 200 on level ground. Outside temp here is around -16c right now
