Tranny Fluid Change

[mjc]

I have an 03 7.3 CC with 66k on it that I bought last July. Love the truck. I want to do a fluid change in the tranny. I do like the Amsoil products so I decided to go with that. First I was going to do it myself with help from someone that know's more then me. Then I decided maybe I should take it to the dealer and have them flush and put in a new filter than put my Amsoil in. It will cost me around $75.00 dollars more going that route then having them do everthing including there Motorcraft tranny fluid. So I talked to a freind that is a GM mechanic to see what his thoughts where. He's not a synthetaic believer so he thinks it is a waste of time. I try to read up as much as possible but I sure don't know everthing. People say it will run cooler so thats a big plus. I like how the synthetics work in the engine when it's 20 below. What are your thoughts, am I wasting my money????

Thanks

Amsoil is one of those things that people really belive in, or they just think it is another lube product. I am sure there will be someone along shortly to tell ya all about it. I like the Motorcraft stuff my self, but that is just me.

I can't help but chime in and plug for the Amsoil ATF. I have a guy who owns his own transmission shop and has been doing tranny work for 30 years and highly recommends the synthetic Amsoil. I have used Amsoil for years and i am convinced that when I got stuck on the wrong mountain road pulling a 29 ft camper and my tranny temps pegged my Autometer guage at 250 plus (before my B&M cooler) that the synthetic saved my tranny. I feel a conventional fluid would have cooked the tranny. Just my 2 cents worth. I sell Amsoil but only after i used it for many years first! I'll put it up against the other ATF's any day.

Hey fleastang, what's the diff between Universal and Torq-Guard tranny fluid?

Thanks for the replies. I'm taking it in Thursday and getting it done. I'm doing to have my dealer do it since he can flush everthing out and pump the new stuff in. I am also changing the filter at this time.


Thanks again.

Hey DocB are you speaking of Amsoil? They have a "Torque-Drive" synthetic fluid. It is primarily for heavy duty trucks like over the road trucks and heavy haul trucks, etc with heavy duty trannys like the Allison, etc.
