You did it wrong when pulling it out. You should have removed the bolts holding the torque converter and pushed it away before taking the engine out. That way the torque converter would stay seated correctly.

Once the torque converter is on the input shaft, turn it and ease it in as far as possible and ensure it is seated correctly.

After engine is in and is flush with transmission, ensure the torque converter turns freely before installing and tightening transmission to engine mounting bolts first.

Tighten torque converter bolts after above steps.

Well I got a change to work on it today with a hoist. And. It looks like I got it to work! Now it is just a matter of putting it all back together and figuring out all the belts. Ill keep you posted if I need assistance with anything else.

Thank you!

Update - It seems to be running ok but sometimes the car's lights will dim and and the car will act like it is going to die to the point where all the cluster lights flicker. Today I cleaned off the positive battery post and it stopped however I recalled that there were 2 things that didn't have a home when I finished the swap. I honestly have no idea where these 2 things belong or what they do. I believe one was taken off the intake manifold somewhere, I have yet to find a plug for it and the other plug is over on the drivers side by the battery and is connected to the wiring harness.

Thanks.

First component is a capacitor, it should be bolted to ground, somewhere on top of the thermostat housing.

As to the 2nd wire, the picture is too concentrated in one area so I am not able to understand what it is for. Some wires are not used as there are for different markets so if you do not have any issues with components etc, then it should be nothing to worry about. Let me know the wire color and I will see if I can come up with anything.

Picture where I am holding the plug is a single red wire with a white stripe and is located next to the battery on the drivers side and goes into the main harness.

The capacitor - I cannot seem to find a plug for it anywhere on the harness by the intake manifold so I didn't plug it in but I do remember unplugging both of these things. The capacitor is a solid blue wire single prong. It is a strange plug style too with a needle like pin right in the center of the inside of the plug.

There should be a connector somewhere near the top rear of engine wireharness that branches out to the TPS and other sensors.

As to the wire, sorry I can't seem to find any reference to it.

I will try to get a vehicle to check and see if I have it. It might take some time as I don't have such vehicles in my shop at the moment.

Have a 1998 Montero and was looking to do an engine swap to the 4M40 2.8L Turbo Diesel that came in oversea markets. Any input would be great. Also, the information you all traded in this post was great!

Are the engine mounts the same for the 3.5L V6 as they are for either the 4D56 2.5 TD or 4M40 2.8L TD? Seems the 4D56 may be easier to get. Also, what about the wiring harness? Do you know of any shops that are very good at this?
