Changing all lubricants to synthetic

So im due to change all the fluids in my 18 sport MT truck. I had good luck with redline in my 2nd gen and want to switch to it for my 18. Does anyone know the quantities of each fluid that I would need. I remember some things are GL4 and some are GL5. Looking for front and rear diffs, transmission and transfer case. I think I heard there was a new special requirement for the transfer case.

The manual has all the info.

 

What's that?

 

I donno, most people seem to use it to start fires or as a chock block or something, because they certainly don't read it.

 

The manual doesnt mention any alternative lubricants. I would prefer to use redline oils.

Just make sure it’s compatible with the type of rubber for any particular system you switch.

 

Who knew?

There ya go brother!

 

Your manual most likely has viscosity and service classifications of most drivetrain lubricants. Start with those ratings and just make sure the synthetic you choose (Redline) meets or exceeds those two specs.

 

Goodie two-shoes.

 

Redline and all other off brands have conversion charts.
