the only product worthy of buying IMO is the ATF 1200, its a HFM ATF and can be used in mercedes benz NAG1 automatic gearboxes, it is also specced for toyota T-IV - but you can buy that from Mobil Askari Lubes cheaper than this I think. - MB ATF 134 is sold as liquid gold in Pakistan for some stupid reason. Shell ATF 134 is about half the price of the old original NAG1 oil which was shell 3403M115. I see this ATF being a cost effective solution for such problem.
Their cleaning product is also good but requires an experienced person to perform the task of using it. The way to use it is to add it to the gearbox and then drive for 10 or 20 kms so that the gearbox shifts through all gears and applies the torque converter clutch too. Then the entire ATF charge of the gearbox requires change so that nearly all of it is removed. The urdu translation is not fully correct because 99% of mechanics and car owners in Pakistan think that the little quantity in the sump of the gearbox is the total quantity. It is not. It is also vital to change the trans pump filter at this time too.
btw - this additive should not be used unneccesarily. ATF itself is a highly detergent oil and cleans gearboxes very good. overusing of this additive may cause failure of gearbox or "stroke" of the valvebody in old hydraulic gearboxes as the dislodged debris can get trapped somewhere else.
