1995 model if it helps.

I found two dipsticks leading to what looks like both sides of the auto box - a long one that is under the intercooler, with pinky fluid in - and one shorter chunky one on the other side of the box (turbo side) with duller brown oil in.................

I got told to put some 75/90 Castrol Syntrax diff oil in the pinky fluid tube.

Is this longer one JUST for the front diff?.........

Is the other little dipstick JUST for the autobox itself??........

Have I screwed up my auto box by chucking in 1/2 a litre of possibly the wrong fliud?....I took it out for a spin, and all seems well, but havn't done any serious mileage in it yet.

Any advice would be awesome. Cheers
