Anyone know a good transmission specialist for Audis in Deira? Need some advice

I've got a 2015 A4 that's been giving me some grief lately – there's a noticeable hesitation when pulling away from a stop, and sometimes it clunks when downshifting at low speeds. I've already done the fluid service not too long ago, so I'm starting to worry it might be something more serious like the mechatronic unit or valve body. I'm based in Deira and I really want to avoid the dealership prices, but I also don't want to trust just any garage with this kind of complex work. I've seen a few places around the Deira industrial area that claim to work on German cars, but it's hard to tell which ones actually have the right diagnostic tools and experience for these S tronic boxes. A friend mentioned a workshop that offers Competent Audi Transmission Deira Dubai  and said they were pretty upfront about costs and didn't try to upsell him on unnecessary work, which is exactly what I'm looking for. I also know that Audi transmissions need specialist equipment like VCDS and OBD tools to properly diagnose mechatronic issues, otherwise you're just guessing . Has anyone here had a good experience with a transmission specialist in or around Deira? I'm hoping it might just need an adaptation reset, but I want to be prepared for whatever they find. Any honest recommendations would be massively appreciated right now. Cheers.
