I called Silver Sport Transmissions and spoke with the man today.
This new transmission is getting noticed. I have a '70 Charger with a 440/493 and an 8 3/4" axle. I asked him if this new transmission offers any advantages over the TKO series.
He said that IF I plan on doing repeated shifts over 6000 rpms or have well over 600 lbs of torque, the new trans is a nice step up.
I have suggested that the torque rating is directly proportional to the traction. If the tires go up in smoke at half throttle, the trans never sees the full impact of the engine. He agreed and said that the TKO can take momentary applications of over 600 ft/lbs without worry. I am probably under 600 so I'm fine.
I ordered a kit with the TKO, a Pistol Grip shifter, hydraulic clutch and all the regular stuff. Total including shipping was $5978 ! What a shock, It was almost $6600 the last time I got a quote!
