I've recently bought a 2003 disco 2 and found out my t case is leaking. It's not leaving a puddle or anything but enough that the light comes on after about 10mins of driving and it'll go off and on throughout driving but I drive 45mins to work and don't want the thing blowing up on me. Would the t case set off the temp light or is it just for the transmission? How would I go about fixing the leak? Easy fix? There's no check engine light on or anything
