I was wondering, what causes the transmission to chatter? My 1926 Fordor does just before shifting into second but goes away after I shift into Second gear. But it happens mostly when I go in reverse. Is this normal?
Sounds like some play in the triple gear bushings.
Peter, what kind of bands are you using? Dave
Are you letting up on the throttle and letting all the way out on the pedal when you shift? Just askin'
Too much throttle and too slow pedal movement. You should engage low or reverse with fairly rapid pedal movement with as little throttle as possible, near idle speed. With practice you will not have any chatter once you master the proper driving technique.
New T drivers often rev the engine way up in anticipation of pushing on the pedal, then gingerly apply the pedal. This causes rapid band wear and failure.
David, I'm using Kevlar bands. Keith, yes, but I think Royce probably has the correct idea. I am a newbie, and have no previous experience with Model Ts. The only way I know how to drive them is from what I have read. I'll try these new techniques this summer, when I get her up and running again.
You need the right kind of oil.
Royce is dead-on
If you cannot get your car into low or reverse at an idle, on flat pavement, then something's wrong. Generally it will be because the engine's too far advanced and the combination of sudden engagement of bands combined with BTDC sparking results in very low torque available. If the band is properly adjusted and ignition somewhat retarded, then the mass of the transmission/flywheel will easily overcome static friction in the drive system.
Remember...you're trying to stop a spinning drum, to engage the planetary system. Is it easier and require less effort to stop a fast spinning drum or a slow spinning drum?
I'm always amazed when I go to tours, how many folks really don't know how the car was designed to be operated, and in the course of the tour really punish their vehicles needlessly. I've also found that if they've driven or owned their car for more than a year, they will likely never take this advice, much less appreciate hearing it.

How very true!
