Need a budget-friendly trans shop near Shabiya – any ideas?

So I'm in a bit of a tight spot financially at the moment, but unfortunately my 2014 A6's Multitronic transmission has decided to start acting up with a really annoying shudder when I'm pulling away from a stop, and I know I can't just ignore it because it's getting worse every day. I live in the Shabiya area and I'm trying to find a workshop that won't charge me an arm and a leg for a diagnostic and repair, because I've heard some of the bigger places in Musaffah can be really expensive and I just can't afford to drop 5,000 dirhams right now. I've been looking for an affordable transmission repair workshop in Musaffah Shabiya  that actually knows what they're doing with CVT boxes, because I know these Multitronic units are quite sensitive and not every garage understands how to properly diagnose them. I've seen a few places mentioned online that seem to cater to a range of budgets, but I'm always skeptical when a place advertises really cheap prices because I worry they might be cutting corners or using substandard parts. I don't want the cheapest option if it means the repair won't last, but I also genuinely can't afford the most expensive option either. I'm hoping there might be a middle ground – a shop that offers fair prices for quality work and won't try to upsell me on things I don't actually need. If anyone in the Shabiya or wider Abu Dhabi area has found a transmission specialist that they felt was reasonably priced without sacrificing quality, I'd really appreciate a recommendation. I just want to get my car sorted without going into debt over it.
