Have to pull and replace engine on my 85 300 SD. Is it best to take out with trans. or separate. Any tips on dos and dont's . I have tried to do a lot of research on matter and mostly seem that a big thing to watch for is the torque convertor in that when you do separate the trans the convertor could go with the engine or the trans depending.And when reinstalling have to make sure convertor is fully seated by revolving it until you hear 3 clunks as I hope I only have to do this ounce. If there might be any members close to me would really appreciate help on matter.

Lots of folks like to pull engine and tranny together. I work alone and find it more manageable separately. Release the torque converter from the driven plate - 6 inordinately small bolts - then push the torque converter back towards the transmission. There's a handling tool that slips into the forward edge of the transmission to keep the torque converter in the bell housing but you can run some stiff wire across the open face of the bell housing. Just pushing back the torque converter ensures it doesn't come out with the engine. If you mean you have a choice, you don't! Make sure the torque converter stays in the transmission. If you don't pull the torque off the transmission, there's no need to confirm 3 clunks or whatever. It's a good time for new input and front pump seals, though...

Start by cleaning everything in the engine bay then fill a memory card with detail pictures.

There's no one "right" way... or even "better" way. I'm in the opposite camp from Sixto. I much prefer to pull the two together. That way I can wrestle with getting the transmission hooked up again outside the car where I've got some fighting room.

Use the method you feel most comfortable with.

The load leveler is a nice thing to have when pulling the engine.
This allows you to adjust the angle of the dangle.

Oh.... if you pull the trans with the engine, drain the fluid out the trans first.......

If you don't you will always remember why you should after not doing it once.

Iam in the camp of pulling eng/trans together.
Much easier to bolt the trans and engine back together when it is in front of you.

Remove the 6 13mm bolts to the Torque Convertor before removing the eng/trans. I learned the hard way, had to set the eng on the tail gate of the PU, and reaching under the trans, remove the dang things.

I have a suggestion on the Load leveler, Cut that little crank off and weld on a large nut, Then you can use your air impact to angle the thing.
I used a long 13/16" Nut, then use a Spark Plug Socket.
A Ratchet works also, just a lot of cranking, still easier than the lil crank.

I'm in the "while I'm at it" camp and would use it as an excuse to stop all of the little transmission leaks and refurbish anything that could be gotten to relatively easily.

I do agree with Charlie and pull the engine and transmission out together. But real words of wisdom are to get those six little studs our of the convertor flex plate before removing. Then when it is on the floor or where ever, just pull the studs out of the bell housing, wiggle it a little and it is out of there.
