Gear Change Issues

I wonder if anybody has any ideas:

Three years ago I had the gearbox rebuilt after gears had seized, upon testing the car the first thing that was not normal was that when it shifted from first to second, it did it with a bang,

B) at times around 40mph in forth gear when it tries to downshift, say going uphill on cruise control trying to maintain the same speed, the whole car rattles; either I select 3 manually or I must throttle down to correct it.

c) After driving on motorway for about 45 minutes, it dowshifts to 3rd even at 70Mph and then to 2nd, at which point I must stop the car and wait ten minutes before driving off again.

- Replaced transmission ECU: all of the above improved but not corrected

- Replaced wire loom: again an improvement is achieved, but still all issues there.

 

Gearbox garage took down whole unit, opened it and inspected and found nothing wrong with internally.

 

Diagnostic returned a fault with the torque convertor but garage said impossible for it to be faulty as it would not drive the way it does now.

 

What else?
