Thetransmission fluid of my explorer 1995 leaked off while on long journey. Realized it late. Topped it up and could drive 30mile/hour. Wouldn'tselect gear 4 and 5 etc.
Was told the fiber warned out. Is this replaceable/repairable or must I replace a new gearbox
Thanks to all for useful advice and tips

Did you add fluid with the engine running while it was in park? Do you have a check engine light or a flashing overdrive light?
