Which AMSOIL trans fluid to use? Other recommendations?

time to replace the trans fluid before the big trip from Texas to Wash DC to my new Army job.

I want to use a synthetic. I have a Racor spin on trans filter and do oil analysis. I want an oil that is ok for extended interval (assuming good analysis results). Amsoil makes two type of fluid appropriate for my truck: Their Universal synthetic and their torque-Drive synthetic. The torque drive appears to have a higher viscosity and maybe according to their site to be appropriate for extended intervals. What do you all recommend? What is the real difference between the two oils?

Was also looking at Redline oil both Synthetic and their high temp synthetic. The high temp has substantially higher viscosity. What drawbacks to using that?

Look forward to your comments.

I just changed the engine oil to Amsoil 20-50 racing Synthetic as I have a 16 gallon keg and thats what goes in my other vehicles.

If I understand correctly, your using this in your diesel? Is it HD diesel rated? I think Amsoil makes a diesel specific Synthetic motor oil that is probably a better choice if Amsoil is your thing. Gasoline rated engine oils regardless of who makes them, won't hold up in your PSD long since oil pressure fires your injectors and the high pressures involved causes foaming of conventional oils that leads to poor running.
