Before I got rid of my 2007 CRD GU, I replaced the standard exhaust system with a 2.5" straight through system as well as a DP Chip.

Not legally so some/most exhaust shops may refuse to do so

Hi folks, Thanks everyone for your help with our problems here, we are a few steps ahead and i thought some of what we have learned will be of interest to you :-D
We have now had her back at a proper Nissan dealer and had the GB relubed. What came out was vile so that was part of the problem. Second, they reckon the next step to eliminate the stench is to check the top boot on the gearstick (which is mentioned elsewhere in the forum and is a known issue).
Next - they actually laughed when we told them the story we were given about the catalytic converter being the cause of the smell. Yes there may be an issue with the Cat, but it sure as eggs isnt going to stink the cab up like that! Verdict - Toyota fed us a line of horse crap. (Gee what a surprise there lol)
Lastly, the age old question about towing in 5th gear..... we asked the service bloke if it applied to the modern vehicles or was just an old wives tale and he adamently told us that towing in 5th will flog the gearbox out double quick. Basically he said the design of the gearbox meant that any undue stress on the vehicle in 5th gear pulled the force of the gears down and off centre, unbalancing the whole set up and more than doubling the strain on the main shaft. Towing in 4th did not use more fuel at reasonable speeds (i.e. 100k/hr and under) and distributed the stress load evenly throughout the box. He also told us the workings of the gearboxes in these were adapted from a truck set up and the main gears are fairly large. Other tips were to use genuine fluid and not to force it into gear... the slight crunch into 4th is 'normal' in them because of the size of the gears.
There you go, the sum total of our lessons regarding our gearbox!! Now to go find the info here on how to pull apart the cab to get to the top of the box and we are off & running again! Keep an eye out for us, 'Slowly But Surely' is our tag and we are not in a hurry! Eastbound mid March :-)
Cheers, Neil & cass
