We need a drawing of a four speed transmission which will be printed on large format pages for mounting on a display board (approximately 20inches by 30inches).
An example is available online at:
http://auto.howstuffworks.com/transmission3.htm
On this page you will see a vector animation of a four speed transmission, and below that, a drawing of a five speed transmission. We want a drawing similar to the five speed transmission drawing, adjusted for the difference in number of gears, which you can see in the vector animation on this same page.
The final product will be full color and ready to print. It should render at 300dpi printed on 20×30 paper. PDF is the preferred format, though I realize I may have to accept another format in order to receive your file. It can be FTPd to my printer when complete.
