Engine from Manuel to Auto Transmission
Soo I recently...oh wait hi! My name is Kevyn and I’m new here so I just finish buying a new engine from a car that was Manuel because my car (A Automatic) started having a knocking noise so instead of rebuild found a new engine with 45k for $1800 now I swap everything over and put the ecu from my old engine on to the new and all my grounds wires are connect and had to switch a lot of components over. With that being said the car now sits on 4 jacks because it cranks really strong but won’t turn over. Everyone telling me I might have to flash my ECU (wink wink) because maybe the engine and ecu are not talking sooo just need help or some advise. Btw I’m a movie when it comes to names of parts more like show me a picture or point it out and tell me to fix it and I’ll know how to do it lol.

That is some project you got yourself into ...... About the engine ...... you say it "cranks really strong, but won't turn over". Do you mean it will turn over but will not fire ... ?? So, where to start. The engine needs compression, air, fuel and spark to run .... right..?? And, oh yes, timing. Let's assume it has compression. Is it getting fuel and air .. ?? Now, what about spark and timing ...... which is controlled by the ECU. That's where I run over my pay grade...... Maybe others will be along to help you out. humfrz |

Yep, that's a good way to learn for sure ...... However, I have a "feeling", that you have reached the point where you need some professional advice in order to get it running. Might I suggest you have your car taken into a automotive shop and have them get it running for you. humfrz |

Is the new engine also a 2013? I wouldn't think it would be that involved swapping a manual engine into an auto. There aren't that many parts that would need to be transferred to the new engine. If I had to guess you have a connector that you forgot. Or maybe one of the ground straps at the bottom of the engine. Do you have any CELs? If so, what are they? |

I don't get it. I thought most race cars now days were paddle shift or sequential without using clutch.

It should work fine
You dont need to reflash ecu Its likely one of the sensors not conmected check maf, map sensors and crank angle sensor, you may have installed something incorrectly this happens to a lot pf guys changing clutch and flywheel then incorrectly install crank sensor wheel Theor are some differences vetween crank sensors on older cars like 2013 and newer 2017 engines not sure if your engine was that new, use sensors off your original motpr |
