I am sure that the '02 has a 47RE. Rebuild kits are not that pricey, and I would suggest new parts rather than swapping from a used tranny. For torque converter, ATS and others habve very good multidisc units. The stock diesel converters are poor quality. I definitely suggest a lockup controller from ATS, in Wheatridge, Colorado. I have their converter and controller, in operation without any issues for 12 years.
