I have Mitsubishi lancer 2004 it was manual 1.3L so a year back the engine seized and i bought a half cut Mitsubishi lance cedia and replace everything thing from its engine bay all wiring are clip to clip it was 1.5L 4g15 engine with F1C1A1-J42 which is a cvt transmission everything was awesome the car was just like a brand new car then suddenly now i have a issue which i could figure out what is the problem, the still running fine no issues at all but the issue is when i am driving and leave the gas pedal the car gives a push just once and when i apply breaks hard to stop the car and when i leave the break pedal as an automatic transmission the car should start moving but it remain unresponsive for a moments like a second or two then push again just like if i put the car in neutral and then to drive and if at unresponsive moment if i apply gas pedal the car jerks so i take my foot off the gas pedal let the car becomes normal then I drive the car and the car drive fine and at the same time the neutral light starts blinking and i have to restart the car then the lights goes away and this happens sometimes only while the push when i leave the gas pedal while driving is constant. Before I thought its an engine issue so i went to mechanic To check the ignition coils and spark plugs and all the sensors but everything was fine then i look at the internet and found out the blinking light of neutral is related to transmission so i went to mechanic again and he told me that i need to change the transmission and said the transmission is bad so i need to change and didnt check what is causing the issue i know for sure the transmission is not bad just something is causing that issue and the issue is not serious because other then the issue the transmission is working fine and i can go up to 170 km/h without any hesitation so if the transmission is bad how can the car reach 175 or 180 km/h one more thing yesterday i was looking at the transmission and saw 4 sensors on it so i unclip them and clean the connections with carburettor cleaner and put them on again by this 1 issue of push is still there but the jerking consistency Became very less but still does but not like before on every stop now it barely even does but still does twice or thrice in a day. Please i need some expert help here or any transmission mechanic Who understood what is the issue please help me out these issues are very annoying or if anyone knows a mechanic expert on transmission in lahore please let me know thank you for your time. And one thing the push is just like when in manual car the ac compressor comes on when driving it give a back push it feel like the same
