I have a 1992 K2500 and while your video is the best on youtube for removing the transfer case and transmission, my truck has a lot of different size fasteners than what you have. I'll put what I remember for what its worth: Starter: 14mm bolts holding it in. 14mm on the main power connector. 8mm on the signal wire. Transmission lines: 13mm U joint bolts: 11mm for the front and rear ubolts; 16mm at the flange where the front drive shaft connects to the transfer case. Cross member: 18mm for the nuts and bolts; 15mm for the transmission mount. Torque converter cover: 15mm; 18mm for the support rods at the top. Torque converter to flex plate: 15mm.

You do realize a half inch equals a 13 mm and a 9/16 is pretty much a 14 mm right....

SBC starter bolts are ALWAYS 9/16s. Doesn’t matter if it’s a 45 year old block or a new production crate engine. Basically 14mm but not.

Hello, update, I recently purchase the haynes 88-98 chevy gmc pickup truck repair manual and found the torque specs listed in the translation section. Now in your video showing a new transmission pan filter and gasket you used a reusable rubber gasket and explained that moroso recommended torque it down to 80 inch lbs. I bought I think a acdelco or napa trans pan filter new with the rubber gasket and it doesn't list the in lbs of torque required to tighten so I'm guessing use the same in lbs torque you did for yours
