105E / 113E / 118E Transmission Back-up light Switch

 This procedure is done with the transmission removed from the car and reverse selector rod removed from the transmission. It's not necessary to completely dismantle the transmission for this step.

Anglia 105E, Classic / Capri, and Cortina MK1 models have a manual activated toggle switch located on the lower end of the shelf as standard or optional equip. After 1967 the back-up light switch were mounted on top of the transmission casing activated by the reverse selector rod.
Any early transmission casings can easily be modified to an automatic back-up light system. By using a reverse switch from the Cortina MK2 or any universal 3/8 x 24 ( 1" long shaft length ) similar switch.

Drill a proper diameter hole directly above the reverse selector rod transmission casing, as pictured, for a 3/8" x 24 tap. Grind a 1.63" end section off the selector rod to create a 9/32" wide flat surface. Then grind a 5/16" long, approx. 20 degree slope at the end of the selector rod for a switch step-up.

Insert the rod in the casing and mount the back-up light switch. Adjust the switch so it will turn on-off ( an ohm meter will do ) while moving the reverse rod. Assemble the transmission for re-installation and mount the switch to the casing. Engage the stick shift in reverse to check activation. Leave the switch installed as it will not interfere with transmission installation.

English Ford Transmission Selector Forks

Worn selector forks or syncro-mesh assemblies can cause the engaged gear to jump out of its position when decelerating.
Assuming all transmission components are in good condition but the selector fork facing on both sides are worn down to 5/32" thick ( new fork facings are 1/4" thick ). This excessive play within the sleeve groove
can cause the transmission to jump out of gear.
One solution is to fill the worn area of each side of the fork by weld brazing up to 1" in length and grind smooth and form to a thickness of 1/4". Do not repair forks that are worn beyond 5/32" thickness. New forks are still available i.e., Burton Ltd.
Displayed are two 113E bronze/aluminum forks from the Cortina MK1. On the left is a worn repairable fork and on the right a reconditioned fork after weld filling and finish grinding.

I have reconditioned steel forks for Anglia 105E transmissions and brass forks for the 113E - 2000E three-rail box and later single-rail Cortina MK2 box. I found that all selector forks for these boxes have a face diameter / thickness of 1/4". Reverse selector forks don't have much wear.
