Gear Oil?

[Jim550Jc]

What kind of gear oil do you guys run weight brand ect. I always used DiaQueen or RedLine in my old DSM, the dealer couldn't tell me anything except that I would run 75W80.
So I thought I'd just see what you guys ran majority wise and just go with that because I'm a follower haha. /ubbthreads/images/graemlins/rofl.gif

Hey Jim, welcome to the site.

Sorry to be the first here to tell you, learn the site search function and bookmark www.vfaq.com. This topic is way beat to death and done ( again ) within the last two weeks. Look for "GM Synchromesh" thread.

Edit, as much as we bitch about the term DSM for our cars your previous TEL experience still applies. Diaqueen GL-4 is not a bad choice. Really just make sure you use GL-4 rated fluid first and foremost.

Yeah sorry about that just wanted to get a conciseness I searched around a bit and that's all I found and it didn't really answer my question that well.
But thanks for your help /ubbthreads/images/graemlins/smile.gif

Diaqueen is good, that's what I have in my trans now. In my other Galant, and my dsm I ran Redline MT-90 in the trans and it worked great. I'd highly recommend the Redline Mt-90 for the trans and Redline Heavyweight Shockproof for the transfercase and rear diff.

I'm on Summit now looking at RedLine I was going to put 75W90 in the T-Case and Trans GL-4 just because the manual and All-Data say so. I'm just confused on the rear end All-Data and the Manual say to use SAE 80W-90 to straight 90W for temps above -10 degrees RedLine only comes in 75-90 for ShockProof, another thing I'm a little confused on will I also need to buy the friction modifier for the rearend because I don't think it's premixed in.

Shockproof is the best thing to use in the xfer case and rear diff. It's proven to provide excellent protection for the gears. You don't need a friction modifier.

For the trans, you'll get a wide array of opinions. I like Neo RHD.

Alright thanks just what I wanted to hear.

redline mt90 in trans and shockproof in xcase and rear end

 

[GSTwithPSI]

Tranny: 1 qt. Redline MT-90, 1 qt. Redline MTL, top off with Redline Heavyweight Shockproof.
Transfer Case: Redline Heavyweight Shockproof
Rear Diff: Redline Heavyweight Shockproof

Or if you want spend a bit more, go with NEO RHD in the tranny and Redline Heavyweight Shockproof in the T-Case and Rear Diff.

Yeah I ended up going with RedLine MT-90 for the trans and Redline Heavyweight Shockproof for the Transfer Case and Rear end.
When I get her filled up I'll have changed every fluid in the car /ubbthreads/images/graemlins/smile.gif and it's on to the visual mods wheels, tint and AMG Parts.

I run Lucas in #476. Ran Valvoline in the ol DSM for years. YMMV. /ubbthreads/images/graemlins/smile.gif

Amsoil or redline they out perform many fluids.
