CLS 350 needs transmission service, anyone know a reliable place?

[samuelfleet]

So my CLS 350 has been shifting a bit rough lately, especially between second and third gear, and I've got that nagging feeling that the transmission fluid and filter are long overdue for a change. I bought the car used a couple of years ago and I don't think the previous owner ever touched the gearbox, so I'm keen to get it serviced before something major goes wrong. The problem is, I've heard so many horror stories about independent garages messing up Mercedes transmissions because they don't follow the proper procedure or use the wrong fluid, and I really don't want to end up with a bigger bill than necessary. I'm looking for a trusted Mercedes repair workshop in Abu Dhabi that actually knows their way around the 7G-Tronic gearbox and has the right equipment to do the job properly. I've seen a few places mentioned online but it's hard to tell which ones are genuinely good and which ones are just good at marketing. Has anyone had their transmission serviced at a specialist in the Musaffah area recently and been happy with the results? I'm especially interested in whether they use the genuine Mercedes fluid and filter, or if they try to cut corners with aftermarket parts. Any honest recommendations would be really helpful because I want to get this sorted before it turns into a more expensive problem.
