Thanks for response. I reached out to the two folks I know with most knowledge that have been inside lots of Toyota transes including one who has been in an RA62 at a Lexus dealership requesting just this (service manual for SS tools... consensus is that it won’t give the specific tool you need but reference a SS set and that to go the SS route would be well into the thousands. There is supposed to be a SA tool to hold trans when you put something crazy like 55lbs tq on a nut when re assembling. My thought there is that I can fab something.
For gear splitters/pullers/etc hoping to find someone that’s been in with universal tools and can give me an idea of what types of pullers to amass (thinking of scouring fb marketplace for a month or so).
All this said your advice is good and was my initial thought. I should put my OWN eyes on the manual before I discount it as helpful.
