Would the problem be the speed sensor or something else?

I replaced the motor in this car, the motor swap went very well. The trans mission worked perfect prior to the swap and now it has the P2770 code and the trans does not appear to shift into 1st gear. The trans feels as if it is in second gear and the drive indicator blinks all the time. fluid is up. Not sure what I could have done wrong? can you give some help?

I have a 2004 honda civic and one morning when going to work it didnt stay on as in when i turned the key it would power on but wouldnt stay on unless i was giving it gas? any help?

My car had been heating up for a while went to get it checked told it was the water pump leaking but now it wont start

My car was having trouble starting but after a few turns I have always gotten it to start. It started getting worse, meaning it would take more turns to get it to start. It also started a wheezing sound as well. A mechanic told me it was the starter motor but when I took it in today they said it was the ignition switch and after installing the ignition switch they are telling me that the starter motor is going as well. Later in the day it was having trouble starting again. I don't know that they were right about the ignition switch.

Changed raditor, thermastat, raditor cap, as i know its proably the head gasket by reading the same issues other people are having. I can here heater core water moving sometimes when turning a corner. Lack of power and just in park it will accelerate high to low alittle on its own. What can i do its a great car 133000 miles on it. checked the oil no signs of mixture and did each spark plug test. Seems just to be the resvior tank overheat steam and guggles.

At regular street speed there is no visible problem.After slowing from let's say 70 to 60 mph,To regain previous speed the engine pushes back and forth or hesitates for a few seconds until previous speed is reached. No dashboard trouble signal. Any suggestions? Thanks!

I'm having issues, and am at a deadlock. My car started overheating on about ten hours into a fifteen hour trip. I stopped, changed the thermostat (because the heat was blowing cold, thought it was stuck shut.) Let the car cool down, and finished the trip with no problems. Same thing happened on the way back home. While running a head gasket sealant, I noticed that my radiator fan wasn't working. I changed the fan switch, still wasn't working, switched the two fan relays, didn't fix the problem, changed the coolant temp sensor, Nada. I also flushed the coolant, hard wired the fan, and some other crazy things. This fan will only come on when the AC is on, and I'm at my wit's end. What am I overlooking? I'm ready to just wire a switch to the dash!

My friend says her mechanic states the trouble codes for a catalytic converter for her car. She's already replaced it and is hundreds in the hole for now. How often does this happen with new cars? I have a '92 Camry with the same converter and only the EGR has been replaced... Anything to be concerned with?

P0700 (transmission control system) P1298 (Electric load detector circuit high input) these 2 codes popped up a couple of days ago. i've had no transmission problems until today no warning signs at all besides check engine light. while vehicle was in drive pressing gas pedal car began to behave like the transmission was in neutral. vehicle would not accelerate. What should be the first thing to look at in this situation? I honestly believe this is a completely electrical problem I am in need of any help that I can get at this point
