I used three of my stock 3 speed transmissions before I went to the 5 speed Ranger trans.
I am very glad I did. Now I have a lower than normal gear for first, great for coming up my steep driveway,
and I have a 5th gear that is my overdrive gear. The 5 speed's 2nd, 3rd, and 4th gears are very similar to the 3 gears
in my old 3 speed transmissions. Consider the cost, $50, and $75 for two Ranger trans The driveshaft (Explorer) cost about $15
at the junk yard. The Ranger rears are very cheap to buy. No adapters needed, only a little machine work on the trans
front cover to match the 5 inch hole it the bell housing. My 38 is a lot easier to drive now, than when I had the stock trans..
