im going this week change the oil seal ring at the left side of rear diff?what oil coul i put there,?the same as in gear.?



thank you for advice

 

gl-4 fluid for the transmission
gl-5 fluid for transfercase and rear diff.

This is for 5 speed and evo 8-9

 

I would use the factory Diaqueen for the transfer case and rear end.

 

OEM fluid for all.

 

You have to be careful with the fluid you use in your MR gear box. I'm not sure which castrol the smx is, but if it's the GL-4 that's used in the viper tranny you're fine. It'll actually provide a good measure of protection while helping to minimize the 1-2 grind. Other than that amsoil and oem diaqueen. For the t-case and diff I've used redline and didn't much care for it, oem and have settled on amsoil 75-140 in the T-case and 75-90 in the diff.

 

ok,and how come the OEM FLUID to tranny and rear diff, is the same and youre using different sae number,i mean 75/140 and 75/90???

 

why not use oem and not worry?

 

I used Redline for the tranny and DiaQueen for the rest.

 

+1 I used amsoil in the tranny but either redline or amsoil

 

Redline for everything...

 

I've heard OEM for all is best, hasn't given my car problems. All preference in the end.

 

ok thanks,i will go with OEM ,and thats it.

 

I use redline shock proof for the trans and oem diaqueen for the transfercase and rear diff I have a 5 speed though use the oem diaqueen for the 6speed

 

and what about the acd/ayc?? the diamond ATF SPIII,?I FOUND Castrol ATF TQ DIII
(TQ Dexron III) ,but the guy in the shop told me its mineral oil,its not fully syntetic.is the diamond atf sp III also mineral oil,or syntetic?
thanks

 

I went with all OEM fluids...but as long as the aftermarket fluid meets or exceeds the Mitsubishi's specifications, then it's your preference..
