Can anyone advise please ?

 

I am planning to flush my gearbox oil as i think it feels a little 'slack'......nothing I can really put my finger on......maybe slow shifts and doesn't really pick up too quickly when I press the loud pedal.

 

Obviously it would make sense to clean the filters and check for debris/filings etc and replace gaskets etc.

 

Can anyone advise the correct service part number or if there is even a service kit available ?

 

I believe the box is a RE4RO3A but asking my local Nissan dealer for any more would be a waste of breath and phone call !!

 

Any advice very gratefully accepted.

What you need to know is without removing the box and torque convertor removing all of the old fluid is impossible, so given that there is a level of compromise you need to do your best to get as much out as possible.

 

So if you have a drain plug ( not all boxes do) then drain what you can from that first and then remove the sump, be aware another litre and half will be lurking in the sump to get you so be prepared.

 

Undo the cooler pipes at the point where the metal pipes change to rubber by the radiator, let these drain also, if you have an air line you can blow these out....a messy job though.

 

With the sump off, the strainer will be seen and needs a few 10mm bolts removing for it to come completly out, as said its a strainer rather than a filter so will have a fine brass mesh that can be cleaned out.

 

Let the box drain for a while with the sump off and once the cooler pipes are off and tightened up refit the sump with a new gasket ( advised) If you cannot get one from your local Nissan tell them there are only two types twin turbo or non turbo or find a local autobox specialits who should be able to supply one.

 

Refill box with at least 4 litres of fluid, check for leaks and then run through all gears with your foot on the brake pedal, check the level again and add as required, following a road test check for leaks again and the level again.

 

Hope that helps

Or do as I did and ask Jeff to do it for me.........

 

.......not just to minimize the effort, but also Jeff can check that all is running properly afterwards. You don't want to do all that work only to find there's another issue with the 'box!!
