3lt 2006 mazda tribute auto v6 as a tow tug?

G/day to all you wonderful people out there enjoying your travels around this beautiul country of ours, I was wondering if there were anyone out there that has a 3lt 2006 mazda tribute auto v6 towing a pop top that could email me to let me know how it performs towing (mine has 100000 kms) as i'd like to tow a pop top around 1100 kg tare 1300/1350 max gvm. Would I need a transmission oil cooler? I have heard that the transmission can be a bit suspect. Any information would be appreciated...... thanks and good luck ...Les
