Hi Shaker,
The gearbox is strong for the motor and has no issues. It is only if you decide to do a conversion up to a 4.2T or Chev V8 that you will "probably" encounter problems if you want bucket loads of torque. Even then the main problem is that the stub pattern to bolt them up is different and there are no adaptor kits.
The early 4.2 gearboxes had the only issues in the Patrol lineup.
Unfortunately it is an urban myth and because the 2.8 gearbox is the same one used in the 300ZX people associate it with being light duty.
I tested mine out pretty well with a Motsons box, Marks crawler gears, 4.88 diffs, 35"
tyres towing a 1.5 ton camper and she stood the task well. I also navied for a guy who had one as his comp truck for the ASCC (now Tuff Tracks) and
Gold Coast 2000 and we had no problems.
The only bad points that I have experienced and heard about is lack of power on take off and the odd cracked head.
I did do a big end bearing on the motor back in 2004 as it was driven hard. I then did a conversion to a TD42T and have never looked back.
Regards
David
