Anyone in Sharjah found a Mustang gearbox specialist they actually trust?

I'm in a bit of a spot with my 2016 Mustang GT and could really use some advice from people who've been through this before. The car's been great for years, but recently the transmission has started this weird hesitation when shifting from 2nd to 3rd, especially when it's cold, and I've got a feeling it's not going to fix itself. I've been looking around at different workshops and found https://gearboxrepairsharjah.ae/brands/mustang/ which seems to focus specifically on American muscle cars, but honestly, there are so many options in Sharjah that it's tough to know who's actually reliable and who's just going to take my money and not fix the problem properly. I've heard mixed reviews about some places in Industrial Area 4, and I'm particularly worried about going somewhere that doesn't have the right diagnostic tools for a Mustang's transmission. A mate mentioned he had a good experience with a shop that does Mustang transmission repair, where they actually used proper diagnostic equipment and gave him a clear breakdown of the costs before they started any work. If anyone knows a place that's honest and knowledgeable, especially about Mustangs, I'd really appreciate the recommendation. I'm in the Industrial Area myself, so anywhere nearby would be a bonus. Thanks in advance for any help you can give, I'm just trying to avoid making a costly mistake.
