I have my local ford only junkyard looking for a for a r2 from a 97 to 03 v6 trans 2wd from an f150 I read other places its the same bellhousing as the 5.0 im not sure if you would know for sure. But I would imagine i would still need the v8 flywheel and clutch parts. Also im goning to be using glow shift gauges so I still have to call them to see how to adapt to their gauge. Also does anyone know how much power that trans can handle in theory? Eventually its going to be reused in a newer ranger build.
I used the clutch, flywheel and starter for a '96 F-150. You need the separator plate from that vintage of truck too, it has a different ring gear depth and to prevent mixups it has a smaller hole for the starter. Use whatever R1 clutchs hydraulic stuff applies for your truck.
On the street I don't know what its power limits are. Most street guys don't care for it because it kinda shifts like a bigger truck transmission, gearing isn't really ideal for racing and there isn't much out there for aftermarket to improve much of anything. Usually they gravitate towards the T-5 (which is weaker but has virtually unlimited aftermarket)
Off the street it isn't highly thought of in fullsize trucks (which are heavier) because it is kinda geared like a car transmission (first is pretty steep especially) and with decent power and tires they are not overly well known for their durability. I suppose 'birds wheelhop thing applies but in slow motion.
I have one in mine so I am not overly scared about it. But it is also in a 4000lb Ranger with a rather weak 200hp 302 and 31" tires. Not a 5k F-150 on 35's with a 351.
