Folks

I have a problem with my box and am a little confused.

Over the weekend i had a trip to london 500 mile round trip. on the way down got stuck in the M25 traffic and it was serious traffic and was stuck in it for 3 hours at crwaling pace. The temp normally sits at 80C however during this time was at 90C.

The problem I have now is when I select R then back to D its harsh. However when the car has been parked up and go from park to D its smooth and no issue. Normally the gear changes are smooth and not harsh at all.

The car is a 1996 C250 TD with 145k miles on it. Ive had the gear oil changed at MB in Bradford at 142k but they didnt change the oil from the torque convertor so only 4 Ltrs were changed. Am wondering if this would make a major difference or not??

I have bought a new thermostate and Rad cap and coolent so all those are getting changed tomorrow and see if the temp goes of 80C again. I dont think the fan kicked in either so most likely going to need to change the thermo coupling i think??

Any help/thoughts are welcome.

Nothing wrong with 90c on a warm day or in traffic.

A 1996 car will have a drain plug on the converter

If it has only ever had ½ changed,,it can only do good to have the full change 75% say that their changes are much smoother after a full change

I 2nd what advice malcom has given you, but do not know why mercedes did not drain atf from torque converter its only an extra 10minutes and extra atf, if your gear changes are harsh after changing atf completly including torque converter,I would check the vacuum on the g/box ,doughnut,propshaft and any movement at rear sub-frame. Hope this helps
