I certainly agree !!!Dodge/ Chrysler actually makes a damn good transmission, its maintenance and operation practice and lack of information that cooks them. My 93 Dodge had 230K on the original trans and that was behind a tuned a 12valve Cummins that was worked. Even then it worked just fine, but as my dad was going to be towing 18K from Delaware to Idaho he decided to swing in a new unit so there was no worries about a failure. We would have done this with any auto honestly. The key to keeping a Dodge transmission alive is first and for most running the right fluid. All of those over drive transmissions were designed to run full synthetic fluid, the Chrysler spec ATF+. Unfortunately its hard to come by even now and so Chrysler said you can run Dextron III in them to get by, but it doesnt flow through the tighter passages of the case and doesnt lubricate the clutches well enough for long term use. So you get slower flow rates wich starves the over drive unit, and increased heat and poor shifts which kills them very quickly. Its kinda like running type FA ATF in a Hydramatic, it will work but not for long. The other big issue is the fact they dont circulate fluid in park. This was done to provide faster warm ups and improved performance of the transmission in cold weather. Unfortunately if you idle them in park for too long the torque converter will generate enough heat in the stagnant fluid that it will burn it, then its game over.
Also the manuals when run behind the Cummins have lots of well documented issues too. The Getrags are known for input bearing failures, and the NV4500s are known for 5th gear failures. And to reinforce the importance of proper oil spec, current conventional gear oil doesnt play well with brass syncros. So if you dont check the bottle to make sure its good for syncroed transmissions its game over there too.
Also didnt Toyota and Honda get in a lot of trouble about 10 years back for buying off outfits like Consumer reports to lie about their products? Also one of the Issues that dinged the GMC Terrain was a simple typo on the tire size decal. Could it be a problem, sure, but its far from a mechanical issue. So that illustrates how broad the term that is applied is when talking about automotive "reliability".
