I had this vehicle in for a driveshaft oil seal last week. after replacement of the seal we filled with oil and it is coming out as fast as we can put it in from inside the gearbox bellhousing. the box is very noisy so i am guessing the diff has put a hole in the casing. now this is the semi auto which i have had no dealings with. looks like the standard old peugeot box with a big electronic change unit bolted on the side.we are removing the box tomorrow but the local breaker says there is a "special" removal mode to set the box into before removal??? any warnings or advice before we tackle this?? i have lexia so should be able to set the vehicle into this mode if indeed it exists. thanks sean
