First thing first-> SEARCH the TRANNY fourum.
All others aside....
I like a cocktail of fluids for my tranny. Here's the whole story.
0-13,000mi --> stock fluid no troubles, one TSD rally (brisk)
13,000 -- 46,000 mi -->DIFF - 3/4qt of super-heavywt shockproof; 75w-90 rest
TRANS - 3.4qts 75w-90ns, super-heavy wt shockproof to fill
At approximately 46kmi I changed the fluids again. atleast 2500mi of Brisk TSD rally and lots of "spirited" driving, no troubles at all whatsoever with the shift. (have to double cluch down into first, always had to even on stock fluids)
After subiegal's testimony on the heavywt shockproof I decided I could use more protection.
DIFF- 100% heavywt Shockproof
TRANS - 2qts 75w-90ns rest w/ heavywt shockproof.
Now It still shifts great when hot, when cold however (as cold as -15F) you have to be really patient w/ the shift.
