Engine mounts are different and so are subframes.
I don't think there are any specialist on such works and it would depend on where you are located. Check oyt the local parts stores for any recvommendations. They would be the best person to recommend any place.

Hi Blaze
I am going to what you've been through. I am replacing the engine on my 1998 minstubishi montero Sport. I put close to 240,000 miles on it. I got a japanese engine with roughly 50,000 miles on it.
I would really apreccieate some guidance. I could not find anything on the internet about engine swapping.
Here is where I am right now: 1. I detached everything from the engine (electrical wires, tubes etc)
2. Took down the starter, detached the AC pump and the steering wheel pump. (Left the AC pump and the steering wheel pump connected to the frame)
3. Took the colant radiator down.
4. The engine is still on its supports. I need to detached the engine from transmission, how do I access all the bolts the are connecting the engine to transmission? A previous answer to your post, suggested lowering the front axle. How far did you lowered it?
Thanks a lor.

You would need to get under vehicle and remove the cover on transmission just after the engine. Once cover is removed, you need to remove the bolts holding the flex plate and torque converter.
After removal of the bolts, push the torque converter as far back as possible.
Remove the bolts holding the engnine and transmission and use a floor jack to support the transmission. You might need to jack up the transmission as you hoist the engine up. Once engine is off the mounts, ( I presume you have removed the bolts) you can separate the engine from trans and pull it slightly forward for lifting it out.

I did all this, and now I am stuck at the two top bolts that hold the engine to the transmision. I am thinking to release the engine from its supports. That would probably give me a few inches so I can access the two top bolts. Other than that, everything seems to be going smooth so far.

Hang the engine with the host. Remove the engine mounts and lower the hoist to gain the space. If you have a flexible coupling socket, you might be able to get to the bolts. Space is tight but manageable.

Reinstall and tighten the 2 bolts at both side of engione block and transmission first. This would allow the upper bolts to be easily removed after loosenning. Failure to do so would result in engine and trans trying to break free of each other and this would hamper the bolt removal.

Thank you KHLow2008. I did just that. I was abble to get the two top bolts after I lowered the engine. Today I finally got the engine out. It came out with the converter from the tranny. Any good suggestion how to put the engine back on? Ofcourse it is going to be the reverse process : ).
Again, advice very much appreciated.

You have to reinstall the torque converter onto the thransmission and ensure it is seated as far back as possible. You need to rotate the torque converter and at the same time lift it to allow it to slip into position. Failure to do so would damage the transmission.

When engine is seated back, ensure it slots in fully and becomes flush with transmission. Do not try to force it in as improper seating of torque converter would cause that. After tightening the engine to transmission bolts and making sure the engine and transmission is flush, turn the torque converter manually. It should turn freely and there should be a gap in between torque converter and flexplate.

You might need to lower or raise the transmission while trying to slot the engine in.

Make sure to detach the flexplate from the torque converter when you re install everything. Flexplate bolted to the engine, torque converter seated as deep as it will go into the transmission. I would add some fluid to the torque converter myself while it is off unless you didn't spill any during removal.

You CANNOT leave the torque converter on the engine while trying to re install it. There is no way you can get the converter to slide into the tranny while the converter is still attached to the engine during re installation of the engine.

Good luck.

How do I acces the bolts on the torque converter, after I put the engine on?

I mentioned getting to the bolts from bottom of engine, after removal of the service cover plate.
