Hi everyone, it's me again. You may remember I recently made a thread about putting a new gearbox in my car. Quick background, it's a '93 mk5 Escort, I've put a mk6 box into it(IB5 type).


The mk6 box has a switch on the...uhh, I guess you could call it rear? Opposite end to the bell housing, at the bottom like(can take a picture if it helps). I don't actually know what it's for, but I know the mk5 box didn't have a switch/connector like this.

Anyhow, my real big issue is that the box is in and works, but it is leaking trans oil HEAVILY from this switch on the box. Does anybody know what this switch is, anything regarding leaks around this switch, and if there's any fix which isn't a whole new gearbox? I'm really desperate, I've only had the car a few months, but if this isn't fixable I'm going to have to get shot of it.


This isn't my box obv, just a google picture, but I've highlighted the switch in question with the red box;
