thnx for your valuable info.

1. Its a full time 4x4. But the shafts are removed already. So my fuel efficiency is still a mystery.

2. Late engage is the current issue. But the gears are not at all harsh. Even the reverse itself smooth to engage. And once the first wakeup start is ok, N to D is very soft. There is no hit/harsh in gears.

Changed ATF 2k Kms ago with oil seal. Recently found a oil leakage and found its from inside gearbox. But the leakage is not as much? When check with Al Nael, they insisted to change the seal inside the gearbox.

3. I wish to believe :) the transmission is still ok. If i need to replace the plates, any idea how much does it cost?

4. What is the fuel pump issue u faced?

5. My Rex will cover almost 200Kms a day. So probably every 5k i will change oil i.e, once in every two months.

There is also a possibility to find issues on the MAF sensor as coupe 2003 said above.
