my matic tranny got busted and hyundai casa advised to rebuild it for a whopping 140k!! In short, i towed out my starex to another workshop and decided to replace it with a surplus matic.

Due to big price difference, I opted to buy a surplus Pajero matic tranny (got it for 7k only in imus as against 35k for a hyundai original). According to a lot of mechanics in banawe, it should work as they have same mitsubishi turbo 4d56 engine (hyundai code: d4bf), just need to reuse the old bell housing. But as we measured the housing it seems all is identical so my mechanic decided to install the pajero tranny as is.

It worked forward and reverse, BUT can not shift-up, most probably due to the electrical system for sensing when to auto-shift. Anyone here knows the trick? I heard there's an need to interchange the wires.
