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

Pretty much what I do as well.

If you are concerned though you can look up the bolt size, TPI/Pitch, and the grade of the bolt to get the general torque specs. Plenty of charts on the internet.

I wish i had the the sense of knowing when it is just tight enough, I don't have the 20 - 30 years experience in bolting up stuff on a car.

You guys are are like the head chef who never follows a recipe, I'm like the apprentice chef, who measures and weighs everything.

I think i have a about ten year to go before I throw away my torque wrenches, verni calipers, and feeler gauges.

I just check hunting till I find the torque specs, or use blue and red locktite on everything LOL !!!

Practice makes perfect. If you are working on something where you have time simply mess around with your wrenches, ratchets, and air tools while following with the torque wrench. It really helps give an idea of what amount of force does what.

After a while you can tell what your impact is doing by sound, and feel. Same goes for wrenches, and ratchets. You can feel it tightening. You can even feel the bolt stretching! The worst part is adjusting your force based on the leverage of the tool. Well, that and if you are messing with stuff like aluminum, or stainless. Yuck.

Unless we hit a time warp, it isn't possible for me to have anywhere near 30 years experience. :sweat:

Oh, after you figure it out you can start betting people you can tighten something within a certain range! Easy money! :D
