Scaredy cat! Putting aside CVT's for a moment, all other automatics found in the majority of today's cars aren't that much different than the 60s ones. Look at the GM TH-4L60E which is (was? been awhile) used in the majority of GM vehicles that are RWD. It is almost the same tranny (with an extra gear and some solenoids replacing some manual valves) as a TH-350 which so many people know and love. Your point still applies today: If you can get it out of the car, you can rebuild it yourself. Many shops choose not to for several reasons: 1) It makes them more money. 2) It is faster. 3) Many mechanics are brilliant top notched ASE x10,000 certified...and then go stupid when they look at a transmission. So they will attempt to fix what they thought it might be, waste 6 hours doing so, and then it still doesn't work so they have to tear it back apart. That effect negates points 1 & 2. It'll also give the dealer/mechanic a bad rep which can hurt business so they just throw a whole rebuilt one in and if it doesn't work, it isn't their problem but the tranny rebuilder's. FWD transaxles are just as easy as they are functionally the same as their RWD counter parts, they just broke the gear train into 2 parallel shafts connected via chain (usually). Now about CVT's, I have not had the opportunity to work on one yet, but I'd like to. Just taking a look at some cutaways of the current Nissan model they're putting in the Maxima's and Sentra's (and probably others) it actually appears to be simpler than a standard automatic. Appearances can be deceiving of course but the overall point was, automatics of today haven't really changed much over the years much like the engine itself is pretty much the same.
