Re: [Chrysler300] You Cars Tranny Fluids





A few years ago there was a pretty lengthy thread on our forum about which ATFs were both suitable and available for our Torqueflites. The original ATF in the cast iron Torqueflite was Type A, but that is no longer being made and offered on the market. I has been conclusively agreed that Type F works very well as a substitute for Type A, and furthermore that most other ATFs, like Dexron and Mercon, will induce disappointing (and sometimes strange) performance characteristics.

ATF is the fluid with the very most critical specifications of any in your car. Getting it wrong can mess up the transmission functions, and even wear it out prematurely. So yes, Go with only Type F in your Torqueflite. 

And your question about synthetic vs. petroleum base? You're probably not going to stress your ATF by racing or pulling a trailer anymore, but it is true that synthetic is superior to petroleum-based in many performance characteristics, and inferior in none. So you'll probably be fine using standard Type F, and you'd be finer yet using Redline  or Royal Purple synthetic Type F.

I have no trouble finding type F at WalMart

So, why mix them at all?

While I had the drivetrain out a couple years ago, I changed the oil in the
trans and the T/C and went with type F

Noticed better shifting right away.

Hi all,

Don't know if this thread has already been done or not don't see anything
so... If these answers are there we apologize, please send us the archived
location(s). Thanks.

1. Is it correct that type F and Dextron are pretty much the same tranny
fluid except the Type F has a slightly higher friction coefficient? There
is no problem with mixing them?

2. We can use any of todays tranny fluids that replace dextron and or
Mercon where either was called for in the original owners manual.? We
happen to have an F with cast iron torqueflite.

3. But what about synthetics vs. Dino tranny fluids? Should one use 100%
synthetics? Can you mix them with Dino. oil too?

4. Also today's tranny fluids, for example Valvoline Dex/Merc lists use in
certain Fords, GM and foreign cars but doesn't list Chrysler as a use for it
but they mean the newer Chryslers right?

Have a few old quarts of leftover type F from somewhere and will use them
over time to keep topping off the F's tranny if I can use them for this.

Thanks in advance for any responses. We appreciate your time and thoughts.

A&G
