Default 4L60E rebuild and parts interchangeability

I have an 4L60e (3KCD) out of an 03 Tahoe that the reaction carrier shattered and one out of a 99 (9KCD) something that the sun shell failed.

Best I can tell the internal reaction gear, internal gear support, sun gear, and low/reverse clutch piston are the same. So, I should be able to use the parts from the 99 to replace the damaged ones in the 03. Am I right?

Also for a stock 5.3L Tahoe which I drive pretty aggressively up and down a mountain everyday and very occasionally do some towing (pulling a truck up said mountain on a car hauler) what are the advantages and disadvantages of switching to the torque converter from a I6 trailblazer? I am planning to installing a large tranny cooler.

Put an 80e in it, please.

Don't waste your time with the 60e and a heavy *** ‘hoe.

I appreciate that, but I need to get this one back on the road next week and it'll become a winter only driver before to long anyways. Presuming I get my two door Tahoe project finished.

So, the plan is beef up the one I pulled out of it a bit and stick it back in. Rather put the into the project.
