Re:
Hi Adam,
I failed to understand from your post why was the original auto transmission replaced in the first place and what was wrong with it. Why wasn't the original transmission re-conditioned?
Please note that I have NEVER come across a failed T30 automatic transmission and I have been across the T30 xtrail since they launched in 2001. Not a single case of total transmission failure came across me in that period, not unless the car was driven with no transmission oil in it anyway.
The description from the mechanic report all points to failed sensors, rather than a faulty transmission and all he needed to do is replace the CAM and CRANK sensors which are known to fail in the T30 models due to age.

Re: ongoing problem with T30 auto transmission - help welcome and needed!
Gday Jalal,
Thanks for replying. In relation to the first transmission, it felt like it started 'slipping' about 2 hours out of sydney. The next morning I continued my journey, and the engine light immediately illuminated. As I was 1000ks from home and had to get home that night so i could look after the kids the next day, I was in a predicament. I Took it to the first mechanic. I will transcribe what was on his invoice,
" Checked for codes and found PO733 3rd gear abnormal. checked auto oil condition and level. Oil smelt burnt. Changed auto oil. cleared codes and tested o.k'."
I drove out the driveway and then about 5 ks' down the road, the same problem reemerged (this time without towing anything (no load). The original mechanic did advise me that if the problem did return that I have broken or stretched one of the 'bands' (from my recollection), and that the prognosis is definitely not good.
Running out of time, as I now had a plane to catch, I limped the car to a mechanic that a friend of mine had recommended. A couple of days later He gave me three options.
1) second hand transmission
2) reconditioned 2nd hand transmission
3) rebuild the original transmission.
At the time, we formed the opinion that we were going to sell the xtrail as we realised that it wasn't suitable for towing. (hence the lowest cost option).
We have since purchased a larger 4wd and the xtrail is now the missus' vehicle. As I said, it has been a brilliant little car for us, apart from this incident we have had no problems.
*********************
Jalal, I really appreciate your feedback, and I can't turn back time, (the auto transmission mechanic here in brisbane also wishes that I still had my original transmission).
So should I look at replacing these two sensors and see what happens? what sort of dollars (ballpark) do you think I would be up for?
So re my Question 1, I am guessing from your reply that there is only (1) one model and variant of transmission for the T30?
Regards
Adam.

Re: ongoing problem with T30 auto transmission - help welcome and needed!
Hi Adam,
I really think this is pointing to when your last auto transmission fluid was changed, so you may need to go back to your service invoices and see when was that done to determine the problem. The error code description HERE gives a clear indication of the causes and it points to the transmission fluid overheating (probably the wrong transmission oil was used). It also refers to a whole heap of other ECU warnings you would get with it (these are explained HERE as well)
Am afraid that replacing the CAM and Crank sensors in this case will NOT solve your problem, but the malfunction of any of these 2 sensors would also cause lack of power and increased fuel consumption. In your case the problem is much larger and it is caused by either incorrect fitment of the replacement transmission (most likely) or a faulty 2nd hand transmission.
I have just confirmed this with Nissan and they told me that there is only one auto transmission for the T30 models.

If there are any problems with the second transmission why haven't you contacted the mechanic to have them repaired under his installation warranty ?
