Non overdrive


Recommended Posts

Hi all

have just bought a 1972 tr6 non overdrive and although I am delighted with the car I am slightly disappointed it’s a non overdrive model,the car is a totally original car with what I think is a good history,and only covered 39000 miles.There are lots of things to do on the car to bring it up to a good standard,but I can’t help wondering about the pros and cons of fitting an overdrive conversion of some sort or keeping it the way it left the factory let alone the cost of the conversion.Any thoughts advice as usual would be most welcome.

regards Nige

overdrive all day long Nige. Huge difference and adds a lot of character and enjoyment to the driving experience. Try ORS (overdrive repair specialists) yes they are not cheap but wonderful quality. Hang the cost...... it will be worth it.

Having driven my TR5 with a misbehaving overdrive for a year (worked occasionally and 20% of the time at best), I can say get an overdrive. It will make your enjoyment of driving the car so much more rewarding.

Hope you enjoy your new toy.

I could not envisage driving my TR6 without O/D end of

Umm. I have a '71 TR6 with OD. I rarely use it, except when a) playing or b) on the 110kmh limited freeway. You have an original, unmolested low mileage car. Maybe consider keeping that way? At least try living with it that way for a while. Or spend the money on cylinder head work or a fancy exhaust manifold!

Cheers,
John

Overdrive for relaxed distance driving and even driving around country roads.

A car is for driving and enjoying. It was an option when new so it's not an outlandish change.

If it is as you say ? don't change it in any way. You do not need the overdrive and the car will not be as it should be.

Perhaps a 5-speed gearbox kit?

I'll get my coat!

As Alan has stated go for O/D. I have used ORS to re-con my overdrive and gearbox, service is very good. They can easily convert a non O/D box to O/D as they do that all the time! Go for it.

I’m no expert but, if it is totally original, why change it? Personally I’d “save up” and have the pot ready when the gearbox needs attention, original cars are increasingly hard to come by. Again, personally speaking, I don’t think the car is a better drive because it had an OD. It’s all personal of course.

My car was non-overdive when I bought it and I kept it that way for eight years.  Going any distance was always a pain because the engine was revving away at normal dual-carriageway speeds.  Having fitted an overdrive box, the difference is chalk-and-cheese.  I have no regrets in changing.

FWIW, I've just had the cylinder head and throttle bodies gas-flowed, for a cost probably similar to what you would pay to add OD to your car. Talk about smiles per mile! I've had to re-tune the PI because so much more air is getting in and out! Now I don't spend much time at motorway speeds (we're limited to 110kmh here in New South Wales), so bear that in mind. Do drive the car before you fork out wads of cash for something you don't need. But if you *do* have wads of cash, put in OD, gas-flow the head, upgrade the exhaust manifold, rebore to 2.7L, add a forged crank...others can help you spend your money! The great thing with TRs is that you will *never* run out of ways to spend money, or advice on how to spend it.
