I had my 4r100 transmission rebuilt. (7.3 diesel) Take off was slow and lack of power in reverse. And it failed with in 200 miles. The cause of failure was the intermediate clutch between 3rd and 4th. Fault code 2nd gear ratio was wrong. After the shop fixed those problems then I had these issues. It would idle in reverse and move and if you gave it more fuel it acts like the brakes are on. Failed in less than 100 miles intermediate clutch failed again. Fixed and still acts the same reverse feels like a brake is on. The transmission shop has no Idea what is going on.
