1000hp 727 full manual build

Just say no to red servos
The core I have has these red servos and I was thinking about swapping ones I have with these. My unit (the one I will be upgrading) has K029 reverse servo and aluminium retainer for it plus K080 front servo both made by Superior. Hope these are better than red Sonnax?
My unt has 4,2 ratio front lever, the core unit has 5.0
My plan is to build 2 transmissions, one for me and one for sale to make all this easier on my wallet. The one for sale will be equipped with 4 pinion aluminium planets, deep factory front drum, both have bolt in sprags already. Also core unit has red aluminium accumulator, mine has standard one wih rod inside so its not moving.
My transmission has old a&a reverse manual valve body, the core unit has tci reverse manual valve body. Both dont have band apply so I will use a&a in unit for sale, and sale the tci vb as well.

I hope this thread can also help people in similar situation to pick no nonsense parts and avoid getting things that look nice but dont give the quality expected.
