I have a 1986 Ford Ranger with the 2.9 and A4LD auto and the TFI module has been consistently overheating on long drives (30+ mins). I changed the thermal compound to Arctic MX-4 and screwed it back down pretty tight with no improvement. I then decided to relocate the module to the fender with a heatsink off of a 90s F150 and it still ends up overheating on drives, but seems to be a little more tame with how fast it started overheating. After driving for about an hour or so, I could feel my truck misfiring a little hard so I figured the module was overheating. I pulled into the garage and touched the heatsink to see how hot it was and it was barely warm. Either the thermal paste isn't effectively transferring the heat, or my module isn't the problem. What thermal paste have you guys successfully used on yours?
