I have civic 1998 VTI model automatic gear... My gear box is making a lot of trouble like if press the pedal the gear dnt shift until i remove my foot. the gears are shifting at very high rpm around 3.3-4k(if i dnt remove my foot from gas the car keep runing in the same gear and dnt change) shifting from 1 to 2 is fine but from 2-3 gives a very bad jerk and down shifting from 3-2 is like i hit the break hard. My mechanic advised me to change the gear box. My car is running with d15 3stage engine (using same old ecu not using 3 stage now). The reason for making this thread is that i wanted to know that can i install prosmatec gear in my car and how much cost will be involved. I live in karachi and is that gear box work fine with my engine.
