Changing transmission lube
 

I've got a Rubicon with an NV1500 5 sp transmission. I need to change the
lube. Pennzoil has some "Synchromesh Fluid" it states it's for Chrysler
products. Part number 12345577. The question is, is this stuff any better
than the dealer's stuff? Or, is there anything better than the Pennzoil? Any
recommendations for the front and rear axles? These are limited slip
differentials. Also, the service manual says to add 4 oz. of Limited Slip
additive. Again, anybody have any recommendations aside from Chrysler?
The service manual just doesn't have that much information.

Thanks

Lloyd Hanning

I believe that synthetic fluids are worth the extra expense.

If you perform all the suggested maintenance exactly on schedule the extra
protective properties are probably not needed.

But that is just my opinion.

Are you sure that its not an NV3550 in your Rubicon? What year is it?
Front & rear Axles should be D44, but the rear "limited slip" could be the
"gear" type, not the "friction plate" type used in the non-Rubicon
applications. If so, the axles don't require the additional Limited Slip
additive. It won't hurt -- its just not needed. Normally any high
quality hypoid GL-5 approved axle lube will be automatically approved for
the plate-type limited slips anyway.

Lloyd, if you have a 5-speed in your Rubicon you have the NV3550. The
Pennzoil is the same stuff you get at the dealer but in a different bottle;
the dealer will charge you through the nose for it.
