how hard is it to change oil and gear box coolers is it a DIY job??

The gearbox has a drain plug so it,s an easy job , the nose panel has to come off ( 2 bolts ) to get to the cooler , if your replacing it with a bigger one you might need to extend the pipes a bit and make a mounting bracket but it,s a worthwhile mod :dance: HTH

What is the best autobox cooler to go for, good place to buy ?

IIRC Zcentre do a oil cooler kit for the autobox , if not just get a 10 row Mocal or similer , any would do as long as its bigger than the original :headvswal

Got 2 fitted on mine , engine oil and autobox , should keep things in check :dance:

thanx for the quick reply, will give them a shout

cheers
