87 300se big transmission problem
I am considering buying (or maybe being given) a broken down 300se from a relative who doesnt know what to do with it.
Heres the situation:
The car will drive and shift ok for first 15 min of operation, then when coming to a stop the engine will die. It can be restarted in park, but as soon as it goes into gear it dies again. After completly cooling down it will run fine again for about 15 min, then same problem over again. It seems like the trans is getting to a certian point and something happens and it bogs down the engine so much it cant run. Almost like lockup TC staying locked.
Any ideas??
(note: i have worked on a couple trans in the past, just no MB ones)
thanks,
Paul

I'd be amazed if that was the problem.. Most likely a fuel pump relay or worst case ignition contol module.

It doesn't have a lockup torque converter. Check all the basics first, plugs, rotor, cap and wires. Check the coil wire where it clips onto the cap base. Mine was burned.
Also as Jonathan wrote, check the fuel pump relay. Typically, they need to be resoldered on some European cars.

Your problem has nothing to do with the transmission as far as I can tell.
Since the car will run for 15 minutes after cooling down, I'd have to go with checking the fuel filter and fuel pump plus relay as others have already stated. Adjust the timing and clean the fuel injectors. That should go a long way in solving that problem. My 500SEL had that issue before and adjustment of timing, cleaning of fuel injectors, replacement of fuel filter and replacement of the idle control unit and idle control valve completely eliminated the problem.
