P1768 code

Apologies the vehicle is 2002 thanks and blessings

Then turn it off it works again then 2 blocks later in neutral again what it be could it be. I have 2000 honda civic was running fine then went into neutral turn it off and back on and it will drive for 2 blocks then same problem. I have flushed tranny, and someone said my main seal was leaking so we changed that to. I have been told it could be neutral safety switch but was told by someone else that switch would make car not run at all then someone said something about cat converter I dont know I am lost

It reads the co2 the transmision fluid is real dark but dont smell and there is no metal only its thick at bottem

It read a sensor code or something then I was saying transmission fluid is real dark and thick with no metal in it. They said the code could be anything from computer loose wire o2 sensor ext

What you mean internal leakages the car ran fine lost no fluid the fluid was nasty the only problem is it slips out gear and it wont go back in until you turn it off and back on then it will only go short distance. I was told if there is no metal in fluid and it dont smell burned the tranny is fine. I cant afford a tranny and I have no friends or family I have to fix this car on my own or loose my job please help

The only code is p1768 also the green d4 light has been blinking since we canged rear main seal. We are looking at the ecm now how would we know if that is the problem once it is off

The D light blinks all the time. I have tried almost everything. When you change the transmission from P to R Or D, it hits really hard and makes the whole car to shake. It fells like if you just crashed into something. The check engine light Is on, The code is P1768. It also wont change gears. You put it on drive and if you don't step on the gas hard the engine will try to go off. Then it dose not change at all. You can step on the gas as much as you want and it wont downshift. I tried to erase the code and it wont. I have replace the transmission and it still does the same thing. An the car that had this transmission was driving fine. I just replaced all the solenoids and sensors in the transmission and its still the same. I also replace the computer (ECM), It's still the same thing. I have no idea on what to do next. I feel like I am going to go crazy. I cant think what else can I do Can someone please Help me.

Thank you so much! Thanks to you I fixed my civic. Thank you so much again and you don't know how happy I am. Hope you guys keep on helping many other people that need your help. The input shaft sensor fixed it cost me $56.00

The problem was going on before we changed rear main seal and read a tcc not o2 I was wrong then after he changed rear main seal the d4 light came on and now the only code reading is that one p1768

Same problem with mine. The sensor fixed it.
