Sounds lame I know, but being new to the Ranger I tried getting a trans filter and the napa guy said well there are three possibilities and he did not know how to tell but may be crawl under neath and get some #s off the trans itself ! Is it really that lame ?
It's a Oct 99 production and it's four wheel drive with a four liter motor, do they really have three trans possibilities ?
Will the vin# help ?

Well from the sticker on the door under TR it says " D " this code is ?
