problem could be a leak in the direct clutch circuit.what MUST BE DONE IS MONITOR THE PRESSURE DROP ON A 2/3 UPSHIFT TO VERIFY NO CLUTCH APPLICATION OR ITS INABILITY TO APPLY BECAUSE OF LOSS OF DIRECT CLUTCH OIL BEFORE IT ARRIVES BEHIND THE CLUTCH PISTON.IF THE TRANS IS ONLY DROPPING 500 ON A 1 / 2 SHIFT THE CONVERTOR IS TOO LOOSE AND IS SERIOUSLY IMPAIRING THE CARS ABILITY TO RUN DOWN THE TRACK PROPERLY.NOW YOU HAVE 2 PROBLEMS INSTEAD OF 1 .IF YOU ARE USING A FORWARD PATTERN OR REVERSE PATTERN FULL MANUAL VALVE BODY IT IS VERY EASY TO DUMP THIRD GEAR OIL INTO THE REVERSE CIRCUIT OR EXHAUST IF YOU ARE NOT FOLLOWING A SOUND PROCEDURE.ALSO THE MANUAL VALVE COULD BE MISPOSITIONED .IF YOU ARE DUAL FEEDING THE HI DRUM YOU SHOULD INSTALL A 2004R LOW REVERSE CUP PLUG IN THE DIRECT PASSAGE AT THE CENTER SUPPORT TO PREVENT THIRD CLUTH OIL LOSS AND IF THE V BODY DOESNT CHARGE HI THROUGH THE REVERSE CIRCUIT SUCH AS THE CASE WITH MANY DESIGNS INSTALL A 2004R PARKING PAWL CUP PLUG IN THE REVERSE PASSAGE OF THE CASE AT THE CENTER SUPPORT PASSAGE.ALWAYS USE CHRYSLER A 604 SOLID TEFLON SEAL RINGS ON THE CENTERSUPPORT AND EPOXY UNUSED PORTIONS OF THE CASE IN THE DIRECT CLUTCH CIRCUIT WHEN THEY ARE NOT USED.WHOS VALVE BODY DO YOU HAVE?I KNOW IT AINT MINE BECAUSE OURS HITS THIRD HARDER THAN 2ND TO KEEP THE SPRAG ALIVE.DONT BLAME THE CLUTCHES AND STEELS,THEY ARE ONLY RESPONDING TO AN INDEXED VOLUME OF OIL CALLED FOR BY THE DRIVER AND SUPPLIED TO THE VALVE BODY BY THE PUMP.LOSS OF THIRD OIL IS WHERE YOU NEED TO LOOK,IM OUT OF TOWN TILL TUESDAY SO IF YOU NEED MORE HELP CALL US THEN
