Turbo5L

Hey guys I've got a ln106 hilux with a 5L diesel in it and a turbo with intercooler setup on it. My drama is the gearbox. I've broken two G52s and just broken a supra box in it. I want to go automatic transmission but it's difficult to find a hydraulic one to go on it because there mainly electronically controlled from what I've studied. And my 5L isn't EFI. Anybody have any info on these gearboxes and which one I can bolt up??
