I have a 4L60E in my '95 GMC 1/2 ton. It is fine, but 1st to 2nd is just a large drop in RPM. If the torque is there to power through it, might not matter much. If I remember correctly the 60 is just an updated 700 (that might be oversimplifying a bit). They can be built too, but consider an 4L80 while you are at it if you are going down the 60 route.
Any idea on how I would handle the kickdown with the 200r4?
