Its been too long since I have done a T-5, so I cant really give you any tips or tricks. I've done several TKO's in the last couple years, but I do know they are different.
IIRC, theres nothing to it. The T-5's use a caged roller bearing between the mainshaft and the input, whereas the TKO/3550 use individual roller bearings. That right there should make things a ton easier.
Follow this link and click on service manual. Section 4.1 has all the parts breakdowns and disassembly instructions.
