there was no DX version that Indus Motors Pakistan assembled, The only 1 model with auto gearbox was the 1/6 GLi which has tachometer.
Now for the engine, pop the bonnet and look at the engine, if its a big rectangle with 4 rubber boots on top and a thick pipe going to the air cleaner its the toyota 4AFE engine which came in the 1.6 GLi - this model had tachometer aka rpm meter as factory original.
If you see a round black frying pan sitting on top of a narrow black engine its the 1.3 litre 2E engine.
