Trying to troubleshoot why my newly rebuilt trans will not shift out of first. Reverse and first work fine. In "1" if I accelerate and then let off the gas, the engine braking occurs. If I'm in "2" or "D", and I accelerate then let off the gas, it freewheels. So something is trying to happen at the point it shifts up from 1st. Here is my question. I have studied the manual schematics, and taken the thing apart and back together, but still do not have a good understanding of how power is transmitted in the various gears. Planetary gear systems are pretty cool, but can be difficult to visualize their various modes of operation. I wish I had a series of drawings of how the power flows through the trans in the various gears. I am assuming that the 2nd gear brake band is utilized only for second gear operation. Do any other pistons operate to activate 2nd gear? Any help/advice appreciated, Edward |
