The Ford Barn

When I first started driving on the farm, my pop had a 1952 F3 with the 4-speed T8 transmission and 11-inch clutch. I was determined to shift that thing with minimal gear clash. I eventually did by carefully listening to engine rpm during shifting. It's an art to match engine rpm to output speed but a person can get a feel for it over time. Double clutching helps but I found that I really only had to do that during down shifting after you get good at anticipating proper engine rpms to output speeds.

The thicker oil helps the countershaft cluster gear to slow down more quickly when the clutch is disengaged. I use SAE 85W/90 GL4 in my 29 model A and have no problem shifting it. I avoid downshifting down to low gear since it is generally only needed when stopping the car. I'll get a click now and then but I don't always concentrate as well as I probably should. When you get used to a car, it starts to become second nature. The car seeps a bit but no worse than any of the other old fords I've had over the years. They like to mark their spot.
