Did you purchase a new modified oil pump backing plate? Did you install the new gasket for the modifed plate?
--> I purchased, what I was assured by New York Hard Parts, was the modified oil pump (complete, not just the plate) and a new gasket.
Were you having problems before the rebuild, slipping, etc. I would say torque converter is a must replacement item when rebuilding atx.
--> I was having problems. The car would accelerate in 1st gear and start to shift to second. Then (insert imagination here) it was like someone had slowly stepped on the clutch and the trans became disengaged. The warmer the car got, the sooner the problem occurred. I realize it's an automatic trans, but the clutch analogy is the best way I can describe it. When I rebuilt the trans, I found that the pump shaft & the inner surface of the forward/direct/coast clutch assembly were both scored. The later part was also replaced. The TC is original. I have the Ford CD and a Ford Technical Manual for the CD4E. I was very careful at every step to measure, check clearances, etc. However, it is the first trans I've rebuilt and I am open to suggestions, criticism, etc.
If you did not rebuild the oil pump, this could have been part of your problem in the first place. The fact that a similar problem occurs in all gears, I think rules out the solonoid body.
--> The solenoid body is original and was re-used, as was the TSS.
How did you install the new piston seals? Did you use a seal installer kit? Did you run pressure checks before final assembly?
--> I installed the piston seals with a jeweler's screwdriver...very, VERY carefully, over several hours. In hindsight, the seal installer kit would have been much faster and well worth the money. I did a pressure check by sticking an air hose in the appropriate holes, using limited pressure (I don't remember the exact amount, but it was fairly low) and listening for the "clicking" of the clutch plates engaging.
In this whole process the one thing that bothered me was the valve body. Several of the valves seemed to stick in the holes & not slide as smoothly as the others. At the time I figured that they were difficult to get out and that was why they were difficult to get back in. Maybe that was a huge oversight..????
Thank you for your time!!
