picked up a rebuilt 4r100 from an 03 off CL got my trans out and their are some differences The t/c from my 99 has 6 bolts and the 03 has 4. the tail shafts on the 99 is steel and has what looks like a speed sensor at the top and the 03 has an aluminum tail shaft with no sensor. when I say tail shaft I mean where the trans mounts up to the transfer case. can I just swap the tail shafts?

Diesels have 6 bolt torque converters, gas engines have 4. Compare the bellhousings on the two transmissions, I'll bet they are different.
