Well it's not for the Blazer, my '67 camaro finally burned up the TH-400... I ordered the Master Racing Overhaul kit comes with everything you need to rebuild it, and I also ordered up a TCI 400 manual with pictures and diagrams to guide me through the rebuild... ARRRGGGHH! minor problem is it looks as though the tranny can't come out unless the engine comes out... the way the cross member is wedged up in between the subframe connectors and the body tub. Anyone have some experience rebuilding TH-400's? Any tips before I tackle this myself? After I get this down I'm gonna rebuild the TH 350 and the NP205 in my K/5 if it isn't all that difficult. With some luck I'll be an auto rebuilding expert...heh. [Real Men Don't Care About Gas Mileage Or Rapid Tire Wear!] 1972 K/5 Ryan B.
