Leaky & Drippin’

Mileage: 108,600KM

Not sure when I had this leaky AL4 but it becomes worst everyday till I had enough of it. Gearbox oil has been dripping heavily and quick solution is needed…

 

 

Here are some of the photos, looks critical to me… took 3 days to fix this leaky AL4. The lengthy period of time was due to a lot of work to bring down the whole gearbox assembly. The whole front subframe needs to be disassembled for easy access to the gearbox area.

Replaced parts

 

A few parts have been identified and replaced accordingly. Since this is a major job taken by the mechanic, some parts which already shows some sign of leak have been replaced as well as preventive maintenance. Changed parts are as below:

  • RH drive shaft oil seal
  • LH drive shaft oil seal
  • Torque converter oil seal
  • Gearbox mid-housing o-ring
  • Sensor o-ring x 3
  • Gearbox oil filter

 

No more leaks

  • Great article Bug. Hey,, just curious, does AL4 transmission ever need to have its oil filter changed? I used to see this being parts sold for other japs make but never quire heard it for Pug except now.

    • It is advisable to change when it is due but to access the oil filter on AL4 is PITA. Some gearbox’s oil filter is situated at valve body area which is easier to replace but for AL4, it is inside the gearbox housing. The best time to replace is when you are planning a major gearbox service like mine. Then it is worthwhile. Just take care of the gearbox lubricant will prolong the filter life.

  • hi bug, i have the unit booked as a 3rd car. it is used and has 50k on the mileage. where i have to start.

    • Hi, first of all. It is better to tag along your trusted mechanic when you do the inspection. If possible try to get access of PP2000 diagnostic machine. You can drive the car to nearest Peugeot workshop to have the car diagnose by the system to find any faults. For 50K mileage, your should have 20K and 40K service records as these considered as compulsory service intervals. It will be a bonus if the previous owner did an oil change in every 10K interval.
