Hi i am looking for some pointers in the right direction as to where my gear box level cap is. I want to apply some dr tranny lube and have been advised this is the the place to put if in.. I would appreciate any help cheers
Only put Dr Tranny in if you actually have a shudder in the TC, and then only consider it as a temporary measure. You'll need to have the TC replaced, and the box fluid replaced asap. Dr Tranny is a friction modifier, and will have a detrimental affect on all the other clutches in the transmission.
Been running drtranny in my d3 for best part of 5 years now, annual oil change and drtranny keeps the judders at bay, box and t/c rebuild half the value of the motor.
No need to go under the car, can be injected via the gearbox oil cooler hoses.
