GQ Patrol, what size trans cooler??

Depends on what you might be doing with it somewhat.
Hauling up the Vic high country is a bit different to cruising along the freeway etc.

Might be best to slip in a temperature gauge to see what it is actually doing.

The transcoolers are thermostat controlled (bypass) so if you were going to fit one I would suggest the biggest you can fit in a fullflow airstream. When its hot it will be in operation, and when its cold the cooler will be bypassed.

by one double the size you have and it will be enough , I have doubts about the t/stat controlled thing . but they won,t lock up the torque convertor
until the oil reaches a preset temp . I,m on my 2nd auto GQ , you will have trouble with the trans hunting at 85kph cos that the lock up speed .
They don,t tow well around the 90kph mark cos of the problem just mentioned . but you can bye a trans locker , and you can adjust what speed you lock the T/convertor .

hi, in reply to the above messages, we have a 17.9ft poptop, 1650kg loaded weight and are planning a trip through the Flinders Ranges and the Eyre Peninsular. and we have just had the trans done up as it wouldn't stay in overdrive and now it's a different car to drive.
thanks from chris.
