Fluids question...

[Cyrk]

Any one know of any cheap prices online to get Mobil 1 Synthetic ATF? I need 14 qts for the full tranny flush and 3 qts for the TOD/Transfers.

Also need some synthetics for the diffs, can any one point me in the right direction, on what kind to use and how much?

My dealers mechanic is hooking me up for my 30k service.

Thanks!

Cyrk, I use only Amsoil. Not cheap, but the best, IMHO.
If your going to buy this much fluid, signup for thier yearly membership. Your discount on cost, more than makes up for the membership price. Throw in some motor oil in the order and your savings will be great!

You may save more by finding a local dealer (if you want to go the AMSoil route) rahter than buying online using the preferred customer method. You'll have to pay shipping (I assume), which may cancel out any savings over local purchase and pickup. There is a form on their website you can fill out to get local dealer info.

(By the way, I used AMSoil ATF fluid for my 30k service. We have GIJoes here in the NW, and they carry AMSoil).

I just get my Mobil-1 ATF and other products at the local AutoZone or Wal-Mart (love the 5-quart Mobil-1 oil jug!). Shipping would outstrip tax on that purchase due to weight, so you'd have to find a deep discount to justify online ordering. Not to beat up on the Amsoil guys, but Mobil-1 ATF has a proven track record (military, industrial and agricultural history) that's hard to ignore. Amsoil is the only other true synthetic, but you really have to wade through their literature to figure out which of their products are or aren't using synthetic base-stocks. IIRC they (Amsoil) have no background or track record with military, industrial and agricultural service.

Cool thanks guys, think I am gonna try the Mobil 1 route...

So what should I be using for the diffs?

Also how many qrt of engine oil is need 5-6?

[Joe_Black]

5 quarts oil, which is why the Mobil-1 5 quart jug is so cool. Plus it's re-useable (with some cleaning) and recyclable. Mobil-1 gearlube works great in the diffs, just remember to pick up some good LSD additive for the rear. I've got some pics in my gallery from my diff fluid change that may be helpful if you've not done it before. Mobil-1 works everywhere!

[Cyrk]

Joe is this the gear oil to use in the diffs?

Also the LSD additive for the rear is that some thing I can just pick up at the store also? What brand do you recommend?

Thanks!

Ok got:
17qts of Mobil 1 ATF.
6qts 75w-90 Mobil 1 Gear Oil.
5 qts of Mobil 1 10w30... think I am good to go.

Also I could only find this LSD additive to use in the rear diff. at NAPA: Trans-X Posi-Trac LSD Gear Oil Additive. Any one know if this stuff will work?

He'll probably pop in soon enough on his own, but I seem to remember Tone cautioning against using any LSD additive.

Most all synthetics do NOT require the use of LSD additive but it will not hurt. BTW, total tranny capacity is 9.1 qts, transfer 2. Front diff 1.5, rear 2.3, and coolant, 9.3 qts.

When I used Mobil 1 in the diff's it did require the additive in the rear to stop the LSD chatter. After moving to Royal Purple I haven't needed it.

[Dallas4u]

Just put it in for peace of mind. Whether it will need it or not, it won't hurt, and it shouldn't be more than like $5 a bottle.

[Cyrk]

Well thanks guys for your help. Just pick her up this morning...
It really shifts allot smoother with the synthetics everywhere!
I added the LSD Additive in also.

He said my transmission fluid was pretty nasty and to keep changing it every 25K miles to be safe also that my TOD looks like it might have a slow leek to keep a eye on it.

The Isuzu mechanics loved the SC!

Gotta love this forum. Thanks again guys.

Did you do a complete tranny flush and fill, or did you just drain the 2 or 3 quarts that normally come out and replace with synthetics? When I tried to swap mine, I could only get about 2-1/2 quarts to drain out, so I just topped it back off with Amsoil and it does seem to shift a lot smoother.

[Cyrk]

I had the complete tranny flush and fill done...
