David, I'll just echo what others have said ... there are no long term
problems from not having overdrive, except for shorter engine life, higher
fuel consumption, and more noise at freeway speeds.
The OD will never pay for itself in engine life or fuel consumption (at
least not at US prices), but IMO the noise aspect means it pays handsomely
in terms of driver satisfaction. I greatly miss mine on the rare occasions
when it doesn't work ! And even though I'm trying to keep my Stag fairly
stock in appearance, I'm already working on installing OD in it.
