Re: 3 speed in SS, which trans with brake
The TH350 ,if the stock 2.48 first gear suits your combo, can be built with an aluminum drum ,TH 400 int sprag , trans brake valvebody for less than half the cost of the Pro Trans.
I would venture a guess that the performance advantage of the Pro Trans over the TH35 would be about .080-.120 second. depending on the ratios used.
