Sugggestion ko ay:

  1. check/correct injection timing, replace air and fuel filters.
  2. Kung hindi mag-improve, pa-repair mo ulit ang injection pump and injectors sa authorized diesel workshop; pero doble gastos ka na nyan.
sir, followed your advice

went to a zexel calibration center

binaba ulit, and was calibrated according to my injection pump and td27 engine specs

after calibration, assembled then refitted back

Yung unang test run, ayaw mag 2nd gear.

They manually adjusted the potentiometer ( ung electrical component on top of my engine pump)

Then ok, nag shift na and it ran smoothly including the shifting, almost perfect i would say. When reaching the 60 kph - turbo all the way na. Tried the Sumulong hiway uproad - no problem unlike before


THen the following morning, i tested my terrano again, To my amazement, it would not shift to 2nd gear again. I have to go to the engine bay area and manually rev the engine to around 2,500 - 3,000 rpm. Then i go back to the driver's seat, drive the terrano and ok na yung shifting

Problem is, when i switch off the terrano and park the it, when i come back to drive the car again, it wouldnt shift until i repeat what i did, that is revving the terrano manually then going back to the drivers seat then run the terrano, and thats the time the terrano will run and all transmision engaged properly

Mali po ba setting ng Potentiometer nito? Or ano kaya possble problems sir?

I will come back tomorrow to have it done again. Hopefully the problem will be solved.

This is the first tie i encounter this kind of problem with my Terrano.

Thanks for previous reply and reccomendations.
