Transmission Question

[sparkycuda]

I am using a Tamiya truck 3-speed transmission for an off-road dump and have a question about the shifting rod and centering springs. Are these springs required or can they be removed and let the servo hold the rod in the position for 2nd speed? Truck will probably be in 1st gear most of the time and thought it might be better not to have the spring compressed so much and would require less torque to shift without them.

Since I don't have experience with this, would appreciate comments and suggestions.

Thanks,

Ken
