Why not the 4t-65HD for the SC version? Is the 65 already beefier, and didn't need a HD version?
(Side question: What exactly is the difference from the 60 and 60HD?)
92-99 NA 4T60
95-96 SC 4T60 HD
96+ SC 4T65 HD
HD gets an extra spider gear in the diff.
that'* prolly the least of it...
when i first started workin around the 4L60/65, the only differences I saw were in the planetary sets and the pan... after a little bit of time and a lot of learning and paying attention, it'* kind of mind boggling the differences (again, this is the L60, but i'm sure the whole setup is very similar to the T60) - once you get down to it, you're looking sometimes at different clutch material, different output shafts (the turbine shafts are usually the same), shot peened output shafts, different valve body assemblies (usually only one valve different between reg/hd), slightly different pump, different spacer plates, etc. there'* a TON of variation...
not nockin what you said, just addin info
