Gady all. I am currently in the middle of my suby conversion into my 86 caravelle and need some assistance with my Auto gearbox. All of the guys in the US recommend putting in a external oil cooler due to the higher rev out put and horse power difference. Chatted to a couple of transmission guys and some VW mech today about this and they thought it wasnt a good idea due to lose of oil pressure in the box. Has any one had any experience with this......Thanks
