transmission fluid change

"Snake oil business method"? Who? GM? I can see that. Many people I know working for them in service departments would probably agree.

As a deductable expense I paid to listen to an ex-Allison engineer speak and elaborate on a number of service issues facing independent transmission repair shops. I also had a chance t interact and exchange info with other folks in the business. Since I didn't see a single representative from any other repair shops local to me I figure I have a leg up on them now. More of one I guess actually. I'm already fixing things they can't. This IS the information age.

Yes. Allisons aren't 4L80e's. Neither is the Mitsubishi I mentioned also as an example. Some people I think got that. Well, I hope.

Guess you're right. My F53 uses many of the same parts as an F550. pretty sure of that because I've already bought and put some F550 parts on it. Ford doesn't classify their trucks medium duty until the F650's. (I looked it up.) Didn't know that where Argosy obviously did, but it has affected my parts sourcing up 'til now not one bit. I had an idea a 19,000 pound vehicle might be on the the lower end of medium classification. Evidently not. Glad to have learned something today though.
