All true with a few exceptions:For Manual Transmissions, your good up until mid 2000's as far as service/rebuilding, especially the most commonly found units in trucks, like the NV 4500 series, as well as the Borg-Warner and Eatons. For the auto boxes, once you get into the Lock Up overdrives like the GM 700R-4, Ford AOD, or Dodge A-904s your going to have to really know your way around them, but the more common like the 4-L60 and -80's as well as the Asian-Warner are not that bad, but Super Expensive even for parts, which are VERY specific to each unit, not just the truck series and options! FORGET Asian and European stuff, your screwed if you have one go bad!
Any of the pre electronic Automatics are pretty simple and easy, just pay extra attention as to how they came apart and follow any instructions EXACTLY, and you should be fine! The Old G.M. Turbo series 350 and 400, the Chrysler Torqueflites, and Ford C-4/6 series are stupid proof as long as you pay attention to what your doing!
Old manuals are also stupid proof, especially the common stuff, New Process, Eaton, Fuller, Dana, Doug Nash, ect. Are super easy to work on and repair, and usually stupid proof!
For transfer cases, all the common ones from New Process and Dana are also stupid proof, and with the N.P. 205/241/248 series, practically Bomb Proof!
The NV4500 in the Dodge 4x4 with Cummins have an issue with the OD 5th gear; the retaining nut comes loose, the gear it slips back off the splines and stops engaging with the counter shaft - stops working altogether. There are various fixes, some work for a while, some don't - not sure which works permanently - yet (mine has stopped working - so I have a 4 speed - 3 speed if you don't count the 1st granny gear). I have not decided yet whether to replace the trans with a 6 speed, something different altogether (10+ speed truck boxes), or just fix the transmission as is - in a SHTF situation, the transmission still works well enough; i.e. it moves down the road at a somewhat reduced speed, but it moves.
Auto transmissions; as I said (broken record) - no roll/push/pull starting. This can be a real issue, especially if you need to move NOW, not hours from now after you have fixed whatever the problem is (starter? battery? solenoid? loose electrical connection?).
My Toyota 4x4 has a button that allows you to engage the starter while the transmission is in gear - can be handy.
