2005 TJL, 4.0L, D-44 rear, D-30 front, 6-sp (AX-15?) transmission.

I've hit the 10k mark and plan to change ALL lubricants and fluids this
winter. I want to make sure I'm using the correct lubricants.

Known fluid types per the owner's manual:
----------------------------------------
Cooling System: Glysantin G-05 mixed 50/50 with distilled water
Axle differentials: 75w-140
Power Steering Pump: ATF+4
Transfer case: ATF+4
Brake Master Cylinder: DOT-3

Unknown fluid types:
----------------------------------------
Clutch Master Cylinder ???
Manual Transmission ???


I plan to use:
----------------------------------------

Axle differentials, Mobil One's LS 75W-140 without additional limited
slip additive

Power Steering & Transfer case: OEM Mopar ATF+4

Brake MC, a good DOT-3, likely Prestone

-----------------------------------------

Problem: I have no idea what should be used for the clutch master
cylinder or the manual transmission.

I suspect the clutch MC uses DOT-3 brake fluid as well (nothing
mentioned in manual), and I'd like to use a good quality manual
tranmission lube, but don't want to pay Dealership prices for OEM stuff.
I've also heard that using hypoid gear lube in Jeep manual
transmissions cause problems with pitting and premature synchronizer
wear. I've seen some use Redline MT products, but I'd prefer to use
something specific to this transmission to avoid problems down the road.

What do the experts recommend? I'm not a cheap bastage: if I have to
pay $21/qt. for Mopar Manual Transmission Fluid, I will. Does anyone
know of a good, cheap source for this?

New car owner, eh? Your best resource is your owner's manual. That bears
repeating. Your best resource is your owner's manual.

AX15 is an Aisin-Warner five speed, of Japanese design and manufacturer,
highly superior to recent American made transmissions. It is similar to
Toyota truck transmissions, and was replaced with a domestic offering before
your model year. You're going to have trouble finding anyone to give you
the straight story on your New Venture (?) six speed transmission's likes
and dislikes. Unless you dunk the vehicle in water however, whatever
transmission fluid you put in it now is good for 100,000 miles or more. I
would therefore put the Mopar Manual Transmission Fluid in it, or whatever
is called for in your Owner's Manual. You really don't need to change
manual transmission fluid on any kind of regular basis, but one change while
the vehicle is more or less new is great. Make sure when you drain it, that
it has a magnetic plug.

Autozone has this. Wow! Clear antifreeze!

Consider a synthetic for improved cold weather performance.

Check your owner's manual on this one. I would expect "Power Steering
Fluid", of which there are two types, Honda and non-Honda. You would need
non-Honda. Definitely confirm with your owner's manual. If they have gone
to ATF+4 for the power steering, this is a great leap forward in terms of
simplicity.

> Transfer case: ATF+4

Owner's manual, but probably right. If you are really going to do this,
flush the whole system. Lots of junk builds up in the lines and calipers
too.

Your owner's manual is a good resource, nudge, nudge, hint, hint. Sometimes
you have to search through it to find what you want.

Call the dealer service department if it is really not in the manual, but
they have been making hydraulic clutch cylinders out of the same stuff as
brake cylinders "forever".

Read the Redline MT propaganda. Find out if it is supposed to be compatible
with your vehicle's warranty requirements. Then make a decision. Either
choice is probably just as good.
