Re: [Chrysler300] You Cars Tranny Fluids

I've been using Dex in my G since the late 90's and can chirp second gear without much extra effort. No problems with the trans except for the dreaded TQ drain back issue that I've never had with any other Chrysler except this one. No leaks if I use it weekly, but if it sits more than 3 weeks (as in winter storage) the TQ will drain into the pan and fluid level will rise and come out somewhere (downshift linkage shaft?) and make a mess unless I put a pan under it.

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.
