I feel your pain. I just paid $4400 for a MB rebuilt trans with torque converter and control unit. The parts alone from MB was $4000. He only charged me $400 labor as he initially quoted me $4000 but MB gave him the wrong parts cost initially. I paid in cash to save on the tax. My 97 E420 has 132K miles. It quite a shame that these MB trans don't last very long. My indy says that this trans is electronic and that was it cost so much more than the 94 E320 rebuilt trans that he installed for $2400 at 78K miles. My 93 BMW 525iT has the original trans with 168K miles although he had to rpolace the trans oil cooler. With the cost of computer controlled parts no one will be able to afford the new car off warranty. It's a mess and will only get worse.
