Re: 1999 Ranger transmission
Late model Rangers did not some with an auxilary trans cooler. Consumer Reports lists the tranny as slightly above average on Rangers for that year. Overall I'd say my old '99 Ranger was better built than the '02 I have now. Also if you disconnect the battery the computer that governs the tranny will reprogram itself and shift firmer, at least for a while. Ranger autos call for a fluid and filter every 30k and fresh lube in the transfer case every 60k. Also there is what's becoming a popular modification, the heralded "throttle cable mod", involving lifting the gas pedal, tugging on the throttle cable to get the slack out, then putting a few small zip ties between the pedal and the bead at the cable end. If the cable is stretched this will improve throttle response a lot.
