300e Transmission swap/ Converter issue
Frankthemoneyman
In the middle of doing a transmission swap on my newest member of the Benz fleet. Bought a 1986 Mercedes 300e in cherry condition except it had a blown transmission. Removed my donor trans from another 1986 300e, that was retired due to electrical problem but it had a factory rebuild transmission.
I was very careful to keep the Torque Converter firmly seated during the removal from the flex plate.
After removing the dead transmission and not being to careful, I noticed that the torque converter on my donor transmission really sticks out a lot more then the other one.
Attempted to rotate the converter carefully back in place but it won't budge.

Does anyone have any advise ?

Do I need to visit a trans shop to have a new seal installed and the torque reinstalled ?

It it sticking out because the pump gear has not been engaged...

DO NOT FORCE IT!! Ask me how I know...

Remove the tranny, and on the bench turn and push until it "locks" in place. You'll know. It will go inside the bellhousing about another inch or so.

At this point, double check you can still see those two notches in the pump gear. If you can and you have not broken them off, you know how it goes back on now Smile

Thanks, nothing broken yet. Had stopped for the one day when I encountered this problem and I was not going to proceed till I figure this out.
To old and in to much pain to do this job twice without a hoist.

I hope you have a transmission jack!

The TC will go in, just keep trying.

Yup, same Transmission jack as yours, judging from the pictures.

Just thought I would share a few things for the shade tree mechanics, like myself.
I did indeed dislodge the torque converter ever so slightly while removing my donor trans, turning the torque converter, with the bell housing up in the air and the tail shaft on the ground was the trick needed to get that torque converter back in place, while carefully turning it.

Finished my transmission swap, job was a success.
The transmission shifts perfectly and performs flawlessly. Grin

I will post some helpful pictures soon. Found a few things that are not in a factory manual but maybe helpful for shade tree mechanics.
One might want to cut a small piece of 1X4 lumber and place it between the valve cover and the firewall to prevent the engine from tilting to farr back and perhaps pinching the brake line that runs behind the engine. Also depending on the condition of your motor mounts, support the front of the engine or place another small piece of 1X4 between the sway bar and the oil pan. Used some duct tape to secure the pieces of wood from falling down while wrenching.
I know that a professional might laugh or make fun of these tip, but it might prove helpful to others with less experience in removing transmissions.
