Beside @ where can you get the sae90 for the t-case
Mobli1 was in my 1st t-case .... iam no my 3rd now

 

Well, i just got back from the dealer and picked up some of the LSD SAE90 oil posted from another thread, the DiaQueen stuff for 46.00 and tax for a 4 liter jug. Will be replacing the Redline 75w90 that i put in the x-fer case and diff.

 

Hey guys,

I've been using Redline GL-4 stuff in the transaxle and NEO Synthetic RHD GL-5 in the tc and rear diff.

I used to have pretty bad decel noise when the car was new, but after changing driveline fluids at ~3k miles and again at 15k miles, the noise is pretty much gone. Or maybe I don't hear it with my exhaust, heh.

A lot of WRX guys have had good luck with NEO and I used it in my wife's WRX with great results.

Did Redline discontinue the GL-4 stuff? I remember seeing a post on this, but haven't followed up since I haven't had to change it. I will do the fluids again at 30k (I'm at 23k now). If there's no more redline GL-4, I will probably try the NEO HD oil which is supposed to work for a GL-4 application. Another Evolutionm member had posted good results with the NEO HD in the transaxle... It is spendy though...

Thoughts?

I know this is an old thread, but Royal purple sells their Max Gear in a GL-5 SAE 90 specification, exactly what Mitsu recommends(for both the transfer case and rear diff). I just ordered some yesterday. The only problem is that it's only avalible in 5 gallon pails for $143.00. Cheaper than I new transfer case though.

 

I have a copy of a TSB, which says you can use also a 75w-90 GL5 oil in the transfer case and rear diff. I have the Mobil 1 75w-90 Gl-5 in those 2 and have not had any problems. It costs $6/qt. I think you need just one qt for the two.

 

Mobil 1 75W90 is GL5 rated which is fine for the transfer case.

 

does anyone have any updates on what they have used in the transfer case?

royal purple, or NEO users?

where can i get some of the NEO stuff?

 

I've been using Mobil1 75W90 in the rear diff (+ lsd friction modifier) and in the transfer case for 20K miles with no trouble. I recently switched to GM Synchromesh in the main gearbox (from the stock GL-4) and it shifts way smoother now. I'm really satisfied with my current driveline fluid setup.

 

Motor - M1
Transaxle - GM synchromesh
TC - RedLine Heavy Shockproof
Rear - M1

Absolutely no problems. The car drives like "butter." I can get away w/ not having to double clutch under some circumstances where before I'd make the TC protest...
