I thought ya'll would get a kick out of this, or enlighten me to something I didn't know. I was at O'Reillys the other day getting some tranny oil to refill it after swapping the rear seal. I was looking for the gear oil and the guy came by and asked me if I needed help and I asked him where the tranny oil is at. He grabbed a bottle of ATF off the shelf and told me to use that, and that everybody uses that nowadays. I believed him for ONE second, then thought WTF? ATF? I actually carried it up to the register, then saw a mazda chilton and some 75W-80 at the front, I gave him the ATF back.... he jsut kinda looked down and didn't say a word....

 

Did you tell the guy it was a manual tranny? I know some trannies take some funny sh*t (i.e. engine oil), but to hand you a bottle just like that is irresponsible.

 

manual Saturns require ATF

 

Some car Manufacturers reccomend atf in their manual trans. I know for sure Chrysler did. It will work, but I would use Redline MTL.

 

This is incorrect. My Dodge uses 10-30 Mobil 1, for MTF.

 

 

There are some manual transmissions that require or recommend the use of ATF. Also, some people do it because they feel it is better for any transmission (wrong) or may make it shift better (somewhat correct, because it lubricates less and thus the syncros work better).

The M-type/R-type transmissions in the FC are not one of these transmissions. Use the recommended fluid in the FSM/Owners manual.

 

How can you say a lower viscocity fluid like trans fluid lubricates less. The lower the viscosity the more lubrication you will get, the more fluid is passed over the surfaces. however the fluid will sheer and break down faster, being the viscosity is lower than recommended.

I do agree. Never put trans fluid where it doesn't belong.

Just for the record, I ran trans fluid just as a flush. With no problems.

 

glhs,
You obviously aren't as old as I am. In fact Chrysler did reccomend atf as late as the 1980's. It was their reccomendation for cold weather shifting problems. Check your facts before you post.

How would you know anything about my age. I would imagine I am older than you, or close to your age.

But thats not the point as of 85 the Dodge FWD used 10-30 oil. This is true.

 

My information comes from factory service bulletins which I read as a normal part of my job as a manager at a Chrysler dealership. As I posted Chrysler reccomended atf to correct shifting problems in cold weather, but also advised that it was suitable year round. The Dodge fwd may have used 10w30, but atf was specified as an alternative.
Unless you were born in 1945 or thereabouts you are not near my age.

 

Wow your 63 and on the internet

You got me on age, thats for sure, but I am more than half your age

 

ATF is a hydraulic fluid that happens to have lubricating properties.

Gear oil (as used in our transmissions) is a high pressure high temp lubricant designed for this purpose.

 

323 GTX uses atf.

 

Friggin' American auto makers using ATF and 10w-30 .

IIRC these will work in any car's MT, but they're really not the greatest thing to use.

 

I had 10w40 in my Honda and ATF in my Saturn, but that is what the manufacturer specd, so go with what Mazda specd.

 

Isn't that a 4 cylinder turbo, 4 wheel drive econobox?

Does it use the same transmission as our FC? Would it not use a transversly mounted engine on a standard FWD transmission with the addition of a transfer case?

 

Point being the guy in the store is a tool and thats why I despise going into auto part stores. They will hire anyone these days. I know how shady they are cause I used to work at one and they told me to sell whatever makes the custmer the happiest even though it might not be exactly what they need. Pretty fucked up huh?

 

I guess the point is use whatever the manufacturer recommends.

Never trust some person handing you parts without checking up specs, especially when it comes to lubricants and fluids and their viscosities.

 

All I was saying is that the 323 GTX uses it, nothing more. Not reccomending anyone put it in their car or anything.
