2012 328i Transmission oil cooler leak

Hi Guys,
I noticed my car is jerking at low speeds from last 10 days, Last week I got "Drivetrain Malfunction" message. Took the car to local BMW specialist. He said the transmission oil cooler is leaking and gave me a quote for $2100 for repair. When asked what exactly he is going to replace, he mentioned below list:

1) Replace Transmission oil cooler.
2) Cooler Housing.
3) Fluid.
4) Re-program the vehicle.

He also warned that the transmission might have damaged and can cost around $7500. I am really puzzled.

My wife drives the car and she only puts around 6000 miles/year. The car currently has 60K miles. I took the car to dealer for oil change in October and he gave a clean report after inspection. Really wondering what might have went wrong within 3 months of light driving.

Also not sure the $2100 quote he gave is justified. He said the leak is showing on the fins so needs to replace all the above list. I am thinking to taking the car for second opinion.

Need help from experts on the cost and the issue with car?

This sounds like BS... did he physically show you it was leaking? If not, run for a second opinion now

Agree this sounds like a fleecing and second opinion is advised. There may be a separate seal that can be replaced rather than entire oil cooler. Look up the part diagram for your car at realoem.com.

I have exactly the same problem.

Had troubles with trans (4.5 liter leaked oil), the mech refilled trans fluid, but suggests to fix the leak and do full trans service - $1800. Not sure if he wants to replace the whole thing or just gaskets.
It still leaking right now, i've been driving it like 10 days, not sure how much oil i lost in these days.
