"The Ins and Outs of Early Ford Transmissions"

By Mac Van Pelt

We realize that it can be nearly impossible to produce a book with all the details and specifications, and not make a mistake somewhere along the line. With that in mind, we have placed this webpage on the internet for buyers to check their purchase against the list of corrections and additions. Any subsequent printings will include this, of course, but the initial printing has a few corrections that we ask you to mark in your book. They are listed below in the order we have discovered the problem, rather than by sequence in the book. The corrections below are placed in bold print.

Corrections:

1) Page 45 - second column - third paragraph: Gear lube capacities should read in "PINTS" rather than "ounces".

2) Page 53 - first table - regarding the 022A-7113-B cluster gear: The rear thrust washer description should read "OBLONG HOLE" rather than "two slots".

3) Page 25 - second column - Figure 6: the part number shown is incorrect. It should read "B-7119" , not B-9118.

4) Page 40 - first column - Figure 48: Not so much a correction as a clarification. This photo shows the late style shifter forks, rails, and related parts. The rails are shown in the book with the three detent notches facing inwards. When installed in the shifter housing, the rails (shafts) should face outward. The forks and other parts are shown correctly. Click here for a revised photo of the parts.

5) Page 9 - first column - second paragraph: the steel pin is 5/16" diameter, not 1/4".

6) Page 58 - In the gear charts, the 48-7106 description should read "Use with B-7108 hub." The reference to a B-7106 hub is incorrect.

7) Page 58 (1st thru 3rd printing) or Page 59 (4th printing) - in the gear chart under the 68-7113, the optional gears listed (last sequence): the item shown as "81A-7107" (which is a brass synchro ring) should read "81A-7017" (which is a main drive gear).

8) Page 52 (1st thru 5th printing) - left side under OPEN DRIVESHAFT TRANS: all references to the 51C-7061 mainshaft are incorrect. The correct part number should read "59C-7061". Also, to be even more specific on application, the 21C-7061 shaft used the 68-7080 rear oil baffle, whereas the 59C-7061 shaft used the 59C-7080 washer in this location. The 1A-7061 shaft did not use either the baffle or the washer.

Additions:

1) Chapter Six: The second printing of the book includes an additional table of specifications: Thrust Washers. You can copy and paste the following table onto a Word document and print it out.
