E240 Auto Transmision judder

My W210 year 2000 e240 recently had gearbox trouble. It was noisy, dropped into emergency mode and didn't change smoothly. A local specialist put new bearings in the box which almost cured it. I am left with an intermittent fault. The transmission will start to judder when driving at a steady speed. Sometimes the judder is preceeded by a drone similar to a noisy diff or wheel bearing. If I lift off the throttle for a moment the judder stops. I can drive for up to 20 miles before it returns.
The specialist suspects the torque convertor but can't guarantee a replacement will cure the fault.
The car has 44,000 miles on the clock and the service history suggests this might be accurate. I suspect the gearbox has run low on oil at some time.
Any ideas please?

We did have the situation with the 211 where the rad leaked into the gearbox oil cooler and gave those exact same faults, If you have a sample of the gearbox fluid tested for glycol that would give an answer.

The new torque converter was fitted to the 211 cars with this fault

Thanks for that.

What do I need to do to eliminate the leak if the test for glycol is positive?

If it is the rad,that is leaking, then it could be cheaper to add a seperate oil cooler, it all depends on the price. If it a positive glycol test the the torque converter also
