That's why I declined the service.I wanted to check with you guys before I did anything.Thanks to everybody.

 

no they just run sone fuel injector cleaner through the intake its b.s. .

 

They are just fishing for business, follow your maintenance schedule and you'll be good.

I am also still a little skeptical of the trans flush, it does get all of the old fluid out of the torque converter, and I'm sure the dealerships like it because it is done through the fill tube, but I still prefer the drain and change of the filter method.

 

Are you sure about that? I know on the Toyotas, there is a whole kit. You remove the bottom of the back seat, remove an access panel in the floor to gain access to the fuel sending unit. Then you disconnect the main fuel supply line at the tank, plug the return line and let the vehicle run soley off of the pressurized can of fuel injector cleaner. I know because I've done it countless times and still have all of the adapters in my tool box. Part of the service WAS to run an additive through a vacuum line when you were done with the kit, but that was only part of it.

 

I've seen an older Ford C-6 stop pulling because of a trans flush. An old timer trans man once told me that flushing an automatic transmission was a bad thing because it actually removes some of the worn off clutch material circulating through the system that helps the transmission with friction for pulling. Sounds just stupid enough to be true. I've built plenty of them...and they are always spotlessly clean going together.......but I don't know about higher mileage transmissions. I think he was right about those.

 

I've heard the exact same thing about clutch material removal, so there must be something to it.

 

Yeah....I've heard it literally all my life. Those old farts ain't so dumb after all.

 

thats what they do to every car im pretty sure, i used to do at the econo i worked at. its just a high concentration of fuel injector cleaner, i dnt belive it does much of anything. u also clean out the mass airflow sensor if im not mistaken.

 

That would do absolutely NOTHING for the injectors. LMAO. All that would do is clean whatever vacuum port you put it in. Damn.

 

full off crap is what they are...
