Tansmission wont shift until high rpms
I have a 1995 powerstroke 4x4 with auto trans, it will not shift until 2300 or so rpms at light throttle and I have to almost let off the throttle to get it to shift any lower than that. It shifts into all gears and seems to drive fine other than that. I just bought the truck and have been fixing alot of small things and have now moved on to this. I drained trans and tc and replace the filter and filled with motorcraft mercon V fluid. The fluid and filter change did not change anything but the fluid that I drained out did not look bad or smell bad. The case of the trans looks like it may have been painted grey at some time which makes me think that it has been remanned at some point. The truck has 190k miles. What should I check, I have acess to a snap on scanner and can look at trans info. It will also downshift from 3rd to 2nd and 2nd to 1st when I am slowing down but still on the throttle, like when I am slowing from 55 down to 30 coming into town it will downshift way to soon so that my rpms are around 2k ( not real sure exact rpm but high). Thanks in advance.
