[Healeys] OD in 2nd gear

[Stephen Hutchings]

I’ve always wondered why first and second were so close (BJ8).
I know, most of us end up using second to start, but that’s sometimes a bit much on a hill, and you’ve got to get out of first quickly, or your change feels like you’ve stayed in the same gear…I guess what was on the parts shelf was limited!
I, too, have tried overdrive on second gear, and I agree with Michael- the overdrive didn’t seem to like it.

I bypassed the OD switch which allowed engagement of 1st, 2nd, and incidentally, reverse.  Being that engaging reverse could be a disastrous no-no, I installed the other switch, a normally closed switch, to bypass my bypass.  Since the shifting mechanism offers the same type of contact surface on that side as is located on the OD switch side, it could be adjusted to prevent the overdrive from engaging when shifted into reverse.
