211 vibrating water from rad in torque fixed

[murray motors]

we are an independent in belfast fri 24th we got in one of the many water in torque converter due to faulty radiator we took of the front bumper took of the gearbox hoses and fitted its own gearbox oil cooler it fitted lovely on the aluminion bumper support had new hoses made at the hydrulic hose shop then rebuilt it.Then we drained some oil from the box put in the new mercedes gearbox flushing oil drove the car for 30 mins.Then we changed the gearbox oil and filter canceled faults and reset adaptions and the car was like a new one no vibrations under load
oil £43 +vat
oil cooler and hoses £120
labour 3 hours
this is a very cheap repair as the mercedes radiator is £560 and the torque converter is £1000-00
drive it all weekend and its great

We have done similar repairs in the past too but have fount the TC does not last. A jolt/vibration may come back in the next 10k.

vibration

I had similar problems with mine, started at around 120K miles. was told new tc only solution at £2500 + ! had trans fluid changed and all was ok , for a while, probably as you say 10k miles , not having £2.5k had fluid changed again and ok for another 10k!. As changes were costing me £120+ decided to invest in pnuematic oil pump, pumped out 3 ltr fluid , put 3 ltr in and fine ( really fine ) for another 10k+ so now when get slight vibration I suck out 3ltr and replace! may not be the perfect solution but damn sight cheaper than a new tc, each change cost around £25 - 30! Oh and now done 225000 mls and running fine and just passed mot at first go!

£2.5k!!!

Who quoted you that!

The TC is £986+vat (I priced one today) plus labour to fit and fluids.

What exactly inside the TC gets banjaxed by the coolant?

I changed the rad in my car , only cost me 180 pounds

I had this issue with my old car, a ex member on here sourced me a new MB TC for £500.

inside the TC is the lock up clutch - similar to the clutches in the box itself, or even a motorcycle clutch. it is the friction surface of the clutch plates that is affected by the glycol, making them judder when in slipping mode (the clutch is either open, slipping or locked).

it is possible that changing the rad for a new one will help fred raven, sounds likely from the symptoms.

I understand that water/coolant in the ATF causes the faces of the friction plates to raise affecting the slipping characteristic.

What causes the torque converter failure of non-contaminated ATF i.e. in the w220?

Is it a mechanical/ bearing failure?

Thanks

I had a Volvo 245 that got water in the slush box and was told by the chap that re-built it that auto clutches use a water-soluble glue because they run in ATF/oil i.e. once water has got in it is strip and re-build time - re-conditioned box and separate oil-cooler.
