I have a 1994 100 with the 2.3 AAR engine coupled to the 097 4 speed auto box.
The milleage is around 270 000km.
The gearbox has very recently started "slipping" between 2 and 3rd gear but it only does this as the car is warming up. It does not happen when cold or once the car has reached operating temperature.
I have been searching the net for information on this gearbox and came up with two articles that seemed relevant.
The first describes my problem as being related to the solenoid pack, in that one of the solenoid could either be worn or has a blockage from sediment.
The second also describes my problem as being caused by the temperature sensor that is located on this solenoid pack.
Which do you think is the most likely cause?
