    My old age and old knees are forcing me to consider an automatic in my Model A. I’m sure that some, somewhere, has done this before. i would appreciate any input. I already have an open driveline and a Ford 8” diff and the original 4 Banger. Motor has been modified and is producing 80-125 HP. I don’t know if the losses caused by the automatic would be too much for it to work.

    Ford C3 transmission from a Pinto / Capri /****** /Cortina
    In the European spec cars they were OK[ish] behind a gutless 1600cc SOHC

    They have a separate bellhousing which would make adapting easier

    I remember reading about one in Rod & Custom in the 70’s that had a Torque Flight mated up to a banger, not real sure what was involved?

    Here is one of Dan Inola's adaptors for a sla camera 11-4-14 216 (640x480) (2).jpg nt 6 trans to model A or B. I would be willing to sell.

    I think the Shay (Model A imitator) uses a Pinto engine and automatic. I think given the similarities, your A would do just fine with an automatic trans, and it would be a reasonable alteration to consider.

    I’m almost 80 and have an F-150 three plus OD trans in my 29 cabriolet, with hopped up banger. I worried about my hip and knees until I started driving it. I was pleasantly surprised my clutch pedal was soft enough to not be an issue. I only changed the clutch arm to a slightly shorter one (from Snyders) and that changed the pedal geometry just enough to give me the softer pedal I needed.
