Ok, I have been reading this forum for a little while, and would have liked to make a first post as a helping hand, but it comes in the form of question, since this has to be the best conglomerate of human resources that happen to be all-knowing when it comes to the random quirks of the explorer.
Anyways, my problem is that I have a 1996 Ford Explorer 4x4 EB, 4.0L 4R55E Tranny. I have recently had to rebuild the transfer case due to the gear comming out of meshing, and grinding. The problem solved, My newest problem comes in the form of the Transmission. The current transmission has 195K miles on her, but only 30K since last rebuilding.
I have no flashing O/D lights, or Error codes being thrown, and yet my transmission seems to slip from 1-2, and from 2-3. It just started doing this recently. It occurs duing natural driving, where it seems to go into neutral during the shift point, then if I let up on the throttle just a little bit, will catch into the gear it should be. 2-3 is quite a bit more exxagerated then the 1-2 slip. If I am above 3500 rpm, say pressing the pedal pretty hard, during the point that the 2-3 should occur it will go into full neutral, and rev to almost 5K rpm, then once the rpms get low enough ( by letting off the throttle, ) will cath into place, however it feels like whenever it does catch into place in either 2nd, or 3rd that there is a little bit of slipping occuring. The torque converter seems to operate fine, in the sense that I can go through the arrangement of gears, and hold the throttle down, and the stall rate is within specs for the manual. During normal driving : 1st, 4th, OD, and Reverse operate very strong, with not signs of degration. I attempted to retorque the Intermediate band, and figured I would retoruqe the overdrive band while I was at it.
My question would come in the form of what are the most likely candidates given the description above. I have read else where that it is possible valve body, or solenoid dirt/clog. This weekend I will be taking the pan off, to check the valve body, solenoids/etc. But I would like to have some input if anyone else has had similar problems. The part that just catches me as odd is that the ECU doesn't catch excessive slippage, or report any error codes. I know the light is not burnt out either, becuase when you turn O/D off it illuminates correctly.
I would be referencing the manual first, but I have lost my manual since I moved recently after getting out of the military. as a side note, I am not afraid to get dirty, and have a pretty large plethora of tools at my disposal, so feel free to get as technical as possible. ( I have all weekend to have fun with it. )

When of when will the poor 4R55E be running again, so I can replace the ring and pinion for the rear (which is showing wear) Curses off roading, so much fun., but so much money

. I think that would probably be the easiest point of entry anyhow, as opposed to taking down the solenoids first, which would probably ultimately lead to the valve body again.
