Yes, it was a lot of money but when I looked at the quality of service, attention to detail, guarantee etc - I'm probably saving money compared to just swapping-in a TCI.
I would recommend Briscoe to anyone. He says my tranny failed after two years because the previous rebuilder had 5 clutches in it instead of 6. Whoa. Crap.
I had him replace the too-stout TCI 2nd gear servo with a more normal Corvettte servo. He also recommend a stouter star shell and his "Torque Bully" planetary. He swapped my torque convertor one that I suspect has a slightly higher stall speed. (Especially in reverse oddly enough.)
My lock-up was never quite right so he's going to put in http://www.ronfrancis.com/transmissionaccessories.htm part # TC-70. It's an adjustable lock-up point. Briscoe says that if I had a different valve body he could set my lock-up point with a calibrated hole drilled in just the right location.
With my 2.78s if I lock-up right away in 4th it'll lug the engine. So I'm hoping to lock-up at around 55 mph.
