This is called throttle pressure. Firmer shifts are a result of higher throttle pressure. Pull the transmission rod away from the shifter arm. I used dielectric grease on this fitting to keep moisture out. It looks like some kind of retaining ring or clip used to locate the rod. Be careful removing switch retainer as its easy to break the small plastic post the switch mounts to.
The filter is a fine metal mesh strainer and can be cleaned in most cases. I presume this is to stop the A clutch pack and associated gubbins from falling out, however once you've removed the bolts the pump readily pulls free with the bellhousing, despite your best efforts. You can adjust this a little tighter or looser if desired, say by a few adjuster nut faces, to achieve slightly more aggressive or slightly smoother shifting. Once the bushings have been located on the car, remove the C-clip that holds the linkage rod on the pin or arm. Overdrive Relay and Function: Overdrive Operation.
Neither it nor the pan need to be cleaned unless major problems have arisen. When reinstalling, use a screwdriver to retract the solenoid post so that the large U-tang on the triangular plastic locking plate will engage the solenoid post between the two metal layers. The debris on filter then starves the transmission pump for oil. If you need more access or need to remove the shifter, disconnect the wiring connectors. If not and provided the nylon bushings are intact, adjust the trans shifter linkage accordingly. Probably 2 more Torx screws hold it in. It took awhile to get 'em back in right.
Replacing the microswitch requires that you lift the shifter as noted below; replacing the shift lock solenoid requires that you remove the shifter from the car. I've found it slides into position easily, with only slight tapping from a hammer. You have to unbolt the shifter and lift up slightly to access switch, but don't have to disconnect anything under car. The shift lock solenoid is mounted on a plastic carrier and is down below on the right, held in place with a small plastic locking tab. It filters down to 30 microns. In other words, alignment on reinstallation is very important.
Find the spot that's best for your driving habits. Transmission fluid will run out when you remove the piece the driveshaft was bolted to flange? Using a screwdriver, carefully open the tangs of the prong and pull the solenoid forward. If you have the Haynes manual for your car, take it with you if go to anyone other than the dealer, as the fluid may have to be drained in a non-standard way via a transmission fluid cooler return pipe non-standard compared to other brands of vehicle. If necessary, use eightofthem's technique of tapping the box downwards onto a lump of wood, but be careful! Will this excersise fix this problem, or just the hard shifting? The cable sheath must be properly seated all the way down into its recess that's pretty hard to miss, but someone could theoretically have later reefed on the cable enough to move it. Now is a perfect time to this little bulb in the socket up under the shift indicator. Is the relay on the relay tray? Note as well the orientation of the hole to the groove. The illustration shows how the shifter mechanism is arranged and where the three donut shaped bushings are located.
Lift up the dust flap on left side of shifter. Replacements come with crimp connectors; anticipating future repairs, I used removable spade connectors insulated with heatshrink tubing. During rebuild I also discovered there are some other poor design issues in this tranny. If it turns, you have ruined the pan. Your transmission has no bands, just clutches.

If it is too tight, just barely loosen one Torx screw on the horizontal brace right behind the fuse panel, pull the bolster panel inward, and lift this brace up. The front two bolts may be obscured by wiring or a bolster support. I've seen a few posts on no reverse and from what I gather, that could be anything from a check ball being stuck or not performing it's job sufficiently due to the fact that it eroded away over the years, to yes. Starting around 1993, a microswitch controls this solenoid. Replaced it with a used one with the two inner o-rings , and the brick is fine.
I believe it is white on that car and square in profile. Unbolt the mount from it and install a new one. I did an 86 740 couple of years ago and works great. Dirt, dust, grime, sludge, wearing through and fraying, all take their toll and cause extra resistance. If throttle pressure wins the contest the trans remains in lower gear, if governor pressure wins the trans upshifts.
