Nissan Navara 2010 Problems

No, an automatic transmission — not to be confused with an automated manual shift gearbox that does use a regular clutch like a manual — doesn’t use a clutch plate. It uses a torque converter, which actually helps when towing because it multiplies the torque down low and that makes it easier to get away from the mark. The thing with the auto, particularly if used for towing, is to have an adequate cooler to make sure it doesn’t overheat and cook the fluid and clutch packs it uses.

Like you, I reckon the Nissan diffs aren't up to the job; we have had a number of readers contact us after having problems. The diff failure is one thing, but it's sometimes compounded by the dealer simply seeking to replace the failed diff with another factory one, instead of having it rebuilt as your dealer did. Replacement diffs obviously take time to procure, which leaves the owner out of wheels while waiting for it to arrive and be fitted.

I would expect a carmaker to have a new diff on hand to replace a broken one in a matter of a day or two at most; to have to wait more than a month is unacceptable and I can understand your frustration. I suspect that Nissan has cut back on parts inventory because of the global financial meltdown, but that doesn't in any way excuse them for what is clearly the shabby treatment you received.
