@XaxoOBoy bhai jan mine is prosmatec. My RPM during auto choke in the morning stays at 1000 but in normal it comes to 700 and even stays there when i engage the gear. If the tranny is ok, it should'nt drop RPM after the gear engaged.
A tip here for auto tranny people: Want to check the torque converter and transmission, Put the car in "D", press the brake padel and push the accelerator all the way down. If the engine dies, get worried about transmission and if engine remains alive. U r Ok
