how to you know which tranny you have in an auto or manual.
isnt there a number somewhere in your engine bay?
whats the difference in locking and non-locking?

 

I was told but forget, the information was somehow related to the information on door jam. Non-Locking is Open Diff . . . more than likely thats the tranny you would want. I honnestly dont know if any maxs cant with a locking diff.

 

well if anyone know this info it would help me a bunch. im going for major power soon so i need a fresh tranny but need to know this info first!

 

For Major Power you would want a VLSD tranny above all, if not an Open Diff tranny to help somewhat balance power down, not as good as a VLSD would but better than a locking diff would.

But if anyone knew I'm sure they'll chime in soon

 

For automatics:

It's on the plate in the engine compartment, on the firewall on the passenger side. Open the hood, look back and to the left, and it's a shiny plate with rows of numbers.

One of the rows will say either
RE4F04A - open differential - One tire can easily spin by itself - bad
RE4F04V - VLSD differential - Both tires will pull together - good

These are the only two types of differentials factory-made for our cars. No lockers.

The number is also on the transmission, I believe. I think the manuals use the same "A" and "V" codes. Seems that the USA did not get the good stuff on a regular basis - most went to Canada on this continent, and Infiniti I30s have a lot of VLSD transmissions as well.

Lucky Canadians.

 

I knew I thought I saw it somewhere. . . faqs.

 

what about this 97 maxima non-locking diff - AOD (SSS) WHAT DOSE THAT MEAN?
i found it on used car-parts.com for 330$ 71,000 on it

 

Jack your car up. Turn one wheel. If the other wheel doesn't turn or turns a little it's an open diff. If both wheels turn at the same time it's a VLSD. If the other wheel turns in the opposite direction of the one you are turning, it's a VLSD that doesn't work anymore (like mine), and fonctions like an open diff.

 

Yeah, bad viscous coupling.

 

Did any 4th gen auto Nissans, as opposed to infinitis ever come with VLSD?
