I dunno what it is. I got it when I got the auto.
The auto is very nice. Plenty of engine braking downhill and so much control going up with the gearing.
And it will still pull 110km/h on the freeway. I also got 12.5 l/100kms going down to cooma. That was at 90km/h due to the front tailshaft vibrations.
When i got my original pootrol diffs the dickhead wreckers gave me one 4.3 and one 3.9 ratio diff and said they were both 4.1's. Needless to say the transfer wasnt real happy about its new roomates and left with a bang.
They also gave me a front diff housing that was so bent I had to cut the tube off to geth the axle out.
