AW4 NO REVERSE OR NUETRAL

Newbe to this forum - 3rd XJ. My current 1993 4.0 AW4/NP231 loads up the engine in park - will not rev over 2000rpm, has no reverse though you can tell it is loading up, has no neutral and will drive forward. All forward gears and shifting are fine including 1st-(2) which is shared with reverse. No bucking slipping all good in forward high reving tire fry ing. Blockage in the valve body? I have changed the fluid & filter (Dex 3) as per dip stick & drain plug. Since the motor was loading up while idling I pulled the fuse on the tcc lock up - no change. I probably have more than one problem and am curious if a mechanical failure in the torque convertor would cause all this. The TPS and NSS are good, I have yet to ohm the Solinoids but have seen nothing about there function that would not allow reverse. HELP
