How do i remove the manual gear selector on a 93 ranger

Do you mean the gear selector physically won't move into the Park position or that it does move to indicate it is in Park but will still roll?
I'm sure you know you have to pull the gear selector toward you to get it into Park.

Loss of reverse gear in an automatic gearbox

Broken Reverse selector Band

Brake material on Selector band is Worn out

Selector band needs sever adjustment

Selector bands hydraulic piston seal had failed

Selector not getting oil to work the piston.

check your brake pedal push down see if your brake lights are coming on if they are not check the switch at your brake pedal that also let you engage tranny into gears

If third, forth, and fifth work OK then there could be a selector problem. Does the gear stick go into the correct position? If so then selector and or other internal problem which will require removal

Check and see if the is a drain plug at the back, bottom or side of the trany, open plug and let drain and then replace gear oil. Other plug will be half way up on the side of the trany.

possible selector linkage adjustment , loose or shifted

Not too sure how common a problem this is but it may have come off the selector rod which is attached to the gear stick. If this is ok then the problem will be inside the gearbox and the selector fork has popped off the selector hub inside the gearbox...It will have to come out if this has happened. So check for any linkages attached to the gearstick an make sure they are still in the arms. Hope this helps, let me know how you get on.

many of these trucks have a mazda trans in them, to remove these shifters you will need to remove the 4 phillips head screws from the corners of the trim around the shifter boot and pull it up out of your way. it's not necessary to remove the boot from the shifter, just lift it up for access to the top of the trans. at the base of the shifter on the top of the trans you will see a plate attached with torx head screws. remove all but 2 of them, now make sure the trans is in neutral and remove the last 2 screws and pull the shifter straight up. the shifter is now out leaving a big hole open on the top of the trans for dirt to fal into so put a wrag in it or screw a piece of cardboard to it. installation is the reverse. good luck

I'd spend the money to change plugs & wires & cap & rotor, if you that style ignition.

Gear selector in neutral, foot on brake, move 4wd gear lever to desired gear, drive.
