First time dealing with a gearbox issue in my old Pajero - any recommendations in Sharjah?

Well, the inevitable finally happened with my 2005 Pajero. Been driving it for years without a hitch, but this week it started with a heavy thud when shifting from park to drive, and now it’s slipping like crazy on the way to work. I’m based over in Al Nahda, so dragging it all over the emirate isn’t really an option. I’m not looking for the fanciest place, just somewhere with honest mechanics who know their stuff and won’t try to sell me a whole new transmission if a rebuild will do. I’ve seen a few ads for general workshops, but I really need a specialist. A friend mentioned a place that focuses solely on Gearbox Repair Sharjah and had a good experience with his Land Cruiser, but I can’t remember the name. Has anyone here used a solid transmission specialist in the Industrial Area lately? Just want to get a proper diagnosis before I’m forced to scrap the old girl.
