CHANGE TRANSMISSION FILTER AND FLUID.IF ALREADY DONE.YOUR MANUAL SHIFT LINKAGE NEED ADJUSTMENT.OR REVERSE BAND NEED ADJUSTMENT OR WORN OUT. DEPEND ON TRANSMISSION TYPE NOT ALL FORD TRANSMISSIONS REVERSE BAND APPLY IN REVERSE.YOU COULD HAVE WORN REVERSE CLUTCH DRIVE PLATES OR LEAKING PISTONS SEALS.
The correct fluid to put in a 1997 van is (ATF-3). Sounds like you need to make adjustment on both the forward and reverse bands of the transmission to correct your problem. The kickdown band (front) forward is located at the top (outside) of the transaxle near the front. To adjust the band,loosen the lock nut approximately 5 turns. With the lock nut loose the adjusting screw should turn freely in case. Tighten the adjustment screw with an inch lb. torque wrench to 72 in-lbs. Then back the screw out 2 1/4 turns, hold the screw in place and tighten the lock nut to 35 ft-lbs. Then after removeing the transmission pan and filter the low-reverse band is located next to the valve body. Loosen the lock nut 5 turns so the adjustment screw is free. Turn the adjustment screw in to 41 in-lbs, then back the screw out 3 1/2 turns. Hold the adjustment screw and tighten the lock nut 10 ft-lbs. Install transmission pan/with gasket and refill transaxle to proper level. Test drive van. Be safe and block the rear wheels before you raise the van and try to work under it. Hope this will help you.
Bands are not adjustable. Why do you think it's a band issue? The band only comes on during manual second gear, not second gear while in drive. It sounds like a check ball was inadvertently left out of the valve body during reassembly.
Try changing the automatic transmission fluid and the transmission filter. There are also bands on the transmission that can be adjusted. You will need to buy the service manual at your local auto parts store to get the exact specifications for adjusting the bands.
Don't have specs on band but the rule is that it should be close enough to the drum to engage without slamming, and loose enough to permit drum to turn without band dragging on it. Biggest problem I've seen people have when adjusting is that adjustment tightens down while turning lock nut. To avoid this, I usually adjust a bit looser than final adjustment so it tightens to correct position instead of becoming too tight. Don't drive 'till you have it right or you will burn band surface. When engaged in reverse, band should be applied and cannot drag. If you adjusted another band, check that one for improper adjustment.
