  What is the best tranny oil to use in my 50 Ford pickup tranny?

  Hey Roy! Welcome to the Early Ford V-8 Club. I have always used StaLube SAE 140 GL4 in my '52 three speed tranny.
You can find it @ some Nappa stores, or order it through Amazon. Have a good thanksgiving! - F F

  Thanks, I read an article about the "yellow metal" which is the synchronizers to be sure to use oil that won't harm them.

  Can I use it in the differential?

  Here are my recommendations for oils to use in your transmission:

If it is a 3-speed conventional synchromesh transmission use Pennzoil Synchromesh Manual Transmission Fluid which has API GL-3 level performance.
If it is a 3-speed transmission with the Borg Warner Overdrive use NAPA SAE 90 GL-1 Gear Oil in both the transmission and the overdrive gearbox - they are interconnected and the fluids used in each will mix.

For your differential use a good SAE 80W-90 API GL-5 Gear Lubricant like Pennzoil Gearplus. The GL-5 oil is a Hypoid Gear Oil specifically formulated for the extreme pressures in differentials.

  Yes you can, but it is not neccesary.
