But ATF+4 is so awesome and should be used in everything because Chrysler back-spec'd it, right?

Anyone really think they tested it on a 1957 Powerflite?
Also Were you born yesterday? LOL

Remember when there were two kinds of ATF and one kind of antifreeze?

Now there are about 127 different kinds

And it's all to provide a superior product.....profit margins NEVER EVER entered anyone's mind.

That's also why there are so many different wheel bolt patterns....sometimes only .3 MM different from each other too.....sometimes on the same model one year apart....because .3MM spread between the lug nuts means the difference between life or death!
114MM has proven to kill everybody but with 114.3 you'll live forever. Safety!
It has nothing to do with profit! Cross my heart and swear on a bible or whatever!
I can't think of any politicians to blame for the wheel bolt pattern thing but there must be somebody....
