Transmission question

I have rebuilt a number of 727's over the years. Follow the FSM carefully and it will turn out well. Be aware that cleanliness is a necessity but achievable in a garage. I have found trans shops and machine shops that will replace bushings if needed for $50, so that is not an issue. For a stock type engine, standard clutches are fine. I like Alto Red and Kone Steels for performance applications. Get a name brand torque converter of the right stall speed. 2500 for mild performance works as 2200 was stock for a 340.
make your own tools from bar stock and angle irons. You need something to pull the pump housing out of the case. I use Unistrut and threaded rod to screw into the pump threaded holes. Comes out easy.
Clamps or bar stock can be used to compress clutch spring for replacing clutches and steels. Use a credit card or thin plastic to guide seals into place. Check operation with air when done.
Be careful with seals as front seal leaks are a pain.
But it will only cost $200-300 for parts from a good supplier (check internet, there are many) to rebuild the trans.
Put in a shift kit if you want to chirp the tires in second gear and have firm and crisp shifts.
Good Luck,
Bob
