MG ZTT 135 + CDTi Auto as a Tow car

[Mark UB]

Thinking of using my ZTT (spec above) as a tow car, will be towing about 1500kg.

It says in owners book max trailer weight for my car (braked) 1600kg.

Does anybody know if all ZT Autos have a gearbox oil cooler as standard (It says in Haynes it has a Fluid cooler)is that the same thing?

Any advice appreciated.
