Exhaust Manifold Bolts
heat shield to transmission.
transmission rear mount.
transmission cross member
Driveshaft- rear axle
Starter to engine
i havent used a torque wrench on these items ever as i do trans R&R for a living and just use my impact guns. 3/8" drive for everything except for the trans to the engine. and for that i use my 1/2" gun with a 3 ft extension. i zip it flush and give it a couple short bursts.
as far as the rear drive shaft, if its steel i use the 3/8" gun, if its aluminum, i tighten it by hand.
the heat shield that goes on the passenger side of the case, i just tighten by hand as well. maybe 15-20 ft lbs.
after 20+ years, i dont have anything come loose on me or do i have a problem with removal in case the trans has had to come back out
