what types of oil (trans & t-case)?
I just bought an '86 Suzuki Samurai and I don't yet own a service manual or even an owner's manual. What type of oil do you guys use in your manual transmission and transfer case? Today, when I drained the existing, it definitly looked like gear lube. I also have an '85 Chevy K-10 pick- up with a NP 208 and that case uses ATF. I filled the Samurai T-case and tranny with ATF. Is that okay? Will it hurt anything? I'm in Alaska and right now the temps are 34-40 degrees. The original gear lube in my tranny was so thick that when I started the Sammy in the morning and let out the clutch it would creep forward in neutral and the RPM's would drop 200-300. This did not seem right. Since changing to ATF my tranny shifts better but my T-case seemed to grind occasionally when I shift into the other ranges on the fly. I don't know anything about Sammys except what I've found on the internet. Did I do the right thing by switching to ATF?

Manual highly recommends 75W-90 gear oil. I have heard of folks using ATF, though.

If it were me, I would change out the ATF and put in Mobil One Synthetic, (about $6.00 per quart here in the "48") 75W-90.

Definitly go with the Mobile1 synthetic it's alot less thick than the 75-90 and should do alot better. I made the switch about a year ago and I'm quite pleased.It,s a little more expensive, but well worth it. Changing the bearings and synchronizers IS NO FUN!!

Go with Mobile 1 or one of the other full synthetics. Mobile 1 is the most readily available. I also use Mobile 1 grease too. Do not shift into low range on the fly. I believe the manual says to have the wheels straight when shifting into hi range 4wd.

Thanks, I'll pick up some Mobile 1 today. I definitly don't want to damage the tranny and t-case.

What's the easiest way to refill the tranny?

I used the fill/check hole with a pump & hose on the lube bottle. Layed on the garage floor. Took about 10 minutes.

Samurais are not designed to run ATF in the drivetrain. Using 75 W 90 synthetic gear lube in cold climates will be your best option. The brand does not matter as long as it meets or exceeds the manufacturer's specifications.
