I bought a subaru B4 ,originally it was an automatic transmission but the then owner had converted it to manual, so when I bought it I thought of reverting it back to it's original state of being an automatic ,
So I changed the gearbox, flywheel etc but the challenge now is that the car seem to be limping ,driving in one gear which is gear number 3,
Am not sure now what might be the cause of that,some are saying it must have an Automatic Transmission Module, some are saying the same ECU for the engine manages the transmission as well,
So I haven't find a AT module for the gearbox to test whether it's true,
Kindly assist me on the way forward
