This has been bugging my, ever since I bought an ATX Focus (ZX3 '01) 3 years ago - an unusual tachometer behavior.
For instance, in second gear, I would lightly press the accelerator, and the tachometer needle would quickly go to around 2000 rpm. I would slowly keep pressing accelerator, the speed would rise from ~25 mph to ~35 mph. But, the tach would stay basically the same, around 2000 rpm. I always thought this is caused by the torque converter and it is normal for automatic. Is it?
What got me puzzled is when I got a coolant flushed a month ago. My car behaved totally differently for the next week or so. Throttle response was so much better, much similar to the manual transmission cars, tachometer was actually following my accelerator input closely. But, this lasted only about a week[

I have no idea what happened[dunno] .
Is this how automatic transmissions (mis)behave?
