Its from a 04 tl 6 speed so it doesnt matter that the motor is from an auto? Nothing needs to be changed on the motor for the swap

you will have to double check the coolant cross over line. I believe the AT and MT are different

No, nothing major needs to be changed when using auto motor into manual car.i did this when i swapped an mt into my auto accord. Only difference i seen was coolant lines on the auto tranny that the manual didn't use. I just plugged them. Going on 5k miles since swap no issues..

yeah theres one coolant hose off of the stock MT j30 block you need to reuse, it literally loops the coolant right back into the block, located under the TB, about the same thickness as the heater core hoses. its on the same coolant pipe as the radiator hoses.

i did the swap, j32a3 from automatic in my accord 6MT, there was ONE sensor on the intake manifold that had a different sized plug, its located behind the TB bolted onto the intake manifold with a vacuum hose keep it from your original block and slap it on the j32 intake. it won't bolt on directly but take the whole bracket from your original intake manifold, you can make it work to stay on with one bolt. if for whatever reason you want it to be bolted securely you can just swap over the whole intake manifold from your j30, as far as i know its the exact same thing.

ill upload pics later.





first picture shows me pointed at that sensor i grabbed from the J30 before i tossed it you can see it goes to that "EVAP SERVICE POINT" thing with the green cap in the second photo, then the second photo is hard to see my finger but im pointing at the hose that loops out and right back in to the block, the inlet and outlet are right next to each other just slightly parallel.

yes i know i left that clamp loose on the sensor lol, i noticed AFTER taking the photo.
