Looking for fluid input for my rebuilt 727

[Lonesome7.3]

I am going to rebuild the 727 in my 72 D200 real soon. I use to just grab a middle quality fluid off the shelf for my servicings. But now, there are a metric butt ton of fluid options. I spent a lot of money getting good parts for this tranny and I want them to last. I do not want to spend money just for the sake of spending it though. So, I wanted to get some input from others who have some experience with these trannies and the different fluid options out there.

Oh, I have a deeper than stock pan and an external spin on filter. So I am packing a lot more fluid this time around.

I use B+M Trick Shift in my '55. Seems to work good. I used it in my 98 1500, Suburban tow rig and my race car with equally good results. i think a remote cooler, along with regular service do more to extend trans life than which fluid you use, though. JMHO

I did not think about Trick Shift

 

[spg]

TCI Max shift transmission fluid or Amsoil Synthetic transmission fluid.

I did nto know TCI made fluid.
