Topic: SOMEBODY TOLD ME..........

[4DEES]

this guy I know told me a while back too use ATF(automatic tranny fluid) in my T-case. I have always used the regular kind,anybody use ATF? are you supposed too use ATF? I was just wondering.

Depends on which t-case.  Don't the t-cases behind automatics use ATF?  I wouldn't substitute ATF for gear oil in the ones behind manual trannys.

gera driven manual cases= gear oil, 75-90 or something
chaindrive auto tranny cases i think share fluid with the tranny=atf

Autos share fluid with the tcase, sucks though when you rebuild one or the other you need to do both. Never heard of putting ATF in a manual tcase, but have heard of putting ATF in your engine about 500 miles before changing your oil, cleans it up real purdy. I guess you could do the same to clean out the gunk in your trans or tcase or maybe even the diff just before you change the oil in them too. I don't think I'd want to leave it in there though.

Some manual transmissions (like the T-5 and late model VW transaxles) use ATF. Could use it in a yota trans or x-fer if the clearences were set up for it. Which I highly doubt.

If you're looking for a lighter weight oil, but still want the durability of gear lube have a look at some of the Redline & NEO synthetic products.

I've heard that running ATF whether it be in ur tcase/tranny/engine, it's a deep cleaner and you don't want to run it permantently.  Maybe a thousand miles, and change it....

if ur runnin atf in ur engine, how much are u puttin, surely, ur not replacing oil with tranny fluid

MY ford f-550 work truck  has ATF  in zee 5speed     but I would never never use ATF in a case made for gear earl

I usually put a 1/2 quart in my engine 500 miles before I change the oil, replacing the oil completly would not be a good thing. FFC is correct ATF deep cleans and still comes with the lubricating properties so it won't harm the internal components. I wouldn't doubt that those expensive additives for cleaning sludge in your engine are for the most part ATF.

In your engine, straight ATF.  No oil.  But like I said, you wanna run it for about a thousand miles, and either change ur ATF to clean ATF, (repeat the process about 3 timesfor better results) or you can just slap oil back in. 

[miks85yota]

sounds like an idea, im just not quite ready to change oil for tranny fluid on a motor i just spent alot of hours  swappin and workin out bugs on, but maybe ill try it

[crawlerdan]

id put a quart in- maybe before an oil change

[miks85yota]

that sounds more doable, does it  work as good as i heard it does?

[crawlerdan]

yep,
atf acts as a detergent, cleans crap off, makes it smooth and shiney

Yeah just run a little bit at a time.  It does the job it just takes longer
