Last minute questions

If you cant afford the $40 B$M kit, you cant afford to mess wiht the control systems of the tranny. You are creating a transmission that will destroy itself over time. Sometimes a little time, sometimes longer. In any case, it aint worth it. The accumulator can operate without the spring. It make sthe 2nd gear band slam on. but, it means if you manually shift, the 2nd gear ban comes on before the low/rev band comes off. It's call "shift overlap" and it wwears both bands and creates a ton of heat and stress. The higher pressure wont help. You need to increase the throittle pressure too to make things work right, and without adding springs in the high gear clutch, it'suseless, and creates more wasted clutch material and heat. If you dont know how something works, don't try to "make it better."
