I believe you have the US built 626 with the ford gearbox
That is even common here in USA - but the problem with these gearboxes is that nearly every used one will be beat to death - the cars meant for mid east have extra transmission coolers in them to cope with the added heat load. They may still fail.
that is why a good repair on these gearbox is far better than a swap. You may need to look hard for a good and reliable person who knows how to repair automatic transmissions. Shooting a used gearbox at the car wont solve anything.
A Pakistani person contacted me to tend to his mazda 626 transmission, his *** story was that he had a mechanic swap in a junked transmission 3 times and every single time he spent a good amount on labor price - and still he had problems.
He is now thinking of junking the car as the cost of a rebuild + all the costs he has spent before would exceed the value of the car.
