GU Patrol Gear Box

David

Your friend should approach his friendly Nissan dealer. A warrantly claim may be accepted by Nissan as I believe there were some faulty gear boxes in this year model.

David,

I agree with Paul, there was a faulty batch between 2000 to 2001 according to Nissan and they repair them even out of warranty as long as the problem was caused by the faulty spline (which is what the problem with these gearbox is).

In answer to your question, yes the gearboxes are the same I think they are even the same ratio, the difference in ratios between the 3.0L and the 4.2 is in the diffs, (final ratio).

Only the leaf spring ute is differant(main shafts are differant)

I had my fifth gear go on my 4.2 patrol a couple of months ago. The 3ltr box has the some problem. The spline was manufactured too short and Nissan cover it. The fault was in 2000 and 2001 Nissans.

Ring Nissan Customer Service and arrange to go to a Nissan Dealer and have it fixed.

You can still drive the vehicle without any damage to the gearbox providing you don't put the vehicle in 5th gear.

Those gearboxes also failed on Series I 1999-build 4.2's, like mine (Dec 1999) did last year at about 120k. Nissan fixed mine under the extended warranty, but I had to pay $100 excess. Nissan, I understand have been fixing them out of warranty anyway. Somehow feel that if they had done it out of goodwill, I would not have had to pay that $100.
I recall 1st gear ratio on the 4.2L turbo was higher than for the non-turbo diesel, so I would expect that ratios would be different for the 3.0 as well.

The 5th gear little spline was fixed in models manufactured after November 2001.

I saw it with my OWN eyes in a nissan workshop manual in a nissan dealership.

pre this date, the 5th gear spline was too short and gives up under stress eventually. 3.0 and 4.2 were both affected.

I have a June 2002 3.0 Td. Towed a 1.5 ton van around OZ..20,000k's at speeds up to 120kph in 5th gear. Its now done 75,000k's and no sign of trouble.

I live in the bush and do heaps of cruis'n in 5th.

Hi people,

I wouldn't hold your breath waiting for Nissan to repair any more early model GU gearboxes. I have a GU 4.2TD manufactured in May 1999 and the 5th gear went on my way back from Alice last week. And before anyone asks, I was not towing.
I took it to Nissan in Brisbane for repair and they filled out a Request For Assistance to Nissan Australia. I just got the response back today.
Their answer is NO.
I rang Nissan Head Orifice and they confirmed that in their opinion the vehicle is too old and Japan will not offer any "Good Will" to repair it. I have 99,940km on the clock.
So now I am going to be $2,260 out of pocket for what Nissan admit is a manufacturing defect.
Go figure.
Needless to say I will be investigating other avenues to stir up a better response. Any ideas?
