My understanding is that the V-6's got a slightly beefier version of the
same transmission. So while they're basically the same, they're not exactly
the same. There was a good discussion of this recently at
According to that the I-4 has the "M5OD R1," which
translates to Mazda 5 speed, Overdrive, Revision 1. The V-6's get the "M5OD
R1HD," HD standing for Heavy Duty. The F-150's get the "M5OD R2," or
Revision 2. My understanding is that you can swap an HD in on a 4 cyl or
even a R2 onto a 4 cyl or V-6 Ranger, but you wouldn't want to take one of
the weaker ones and mate it to a stronger engine.
Hope that makes sense,
