nigelcurry Posted September 1, 2020 Report Share Posted September 1, 2020 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 Quote Link to post Share on other sites
cp25616 Posted September 1, 2020 Report Share Posted September 1, 2020 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. Alan G Quote Link to post Share on other sites
Aldpilot Posted September 1, 2020 Report Share Posted September 1, 2020 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. Mike Quote Link to post Share on other sites

Nigel Triumph Posted September 1, 2020 Report Share Posted September 1, 2020 Sounds like you've found a great car. But overdrive will, without doubt, make it even better. If you can find the kit to convert it, don't hesitate, just do it. Nigel Quote Link to post Share on other sites
JohnC Posted September 3, 2020 Report Share Posted September 3, 2020 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 Quote Link to post Share on other sites
4Mal Posted September 3, 2020 Report Share Posted September 3, 2020 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. Quote Link to post Share on other sites
71 V12 Posted September 3, 2020 Report Share Posted September 3, 2020 In my view it depends how you will use the car. If you intend to long haul trips and O/D is a distinct advantage. If use is going to be limited to mostly local trips and commuting in traffic I would say the cost and work is not worth it. Quote Link to post Share on other sites
Harbottle Posted September 3, 2020 Report Share Posted September 3, 2020 If its there you can use it, if its not you can't. Get overdrive and when you are out cruising at any decent speed you will appreciate it. Paul Quote Link to post Share on other sites
harlequin Posted September 3, 2020 Report Share Posted September 3, 2020 Why not cadge a ride in a car with overdrive or even rent one for a day then you can make your mind up a minimal cost George Quote Link to post Share on other sites

You do not need the overdrive and the car will not be as it should be. Quote Link to post Share on other sites
Bill944T Posted September 3, 2020 Report Share Posted September 3, 2020 Perhaps a 5-speed gearbox kit? I'll get my coat! Regards Bill Quote Link to post Share on other sites

They can easily convert a non O/D box to O/D as they do that all the time! Go for it. Bruce. Quote Link to post Share on other sites

Paulfc Posted September 4, 2020 Report Share Posted September 4, 2020 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. Quote Link to post Share on other sites
RobH Posted September 4, 2020 Report Share Posted September 4, 2020 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. Quote Link to post Share on other sites
JohnC Posted September 6, 2020 Report Share Posted September 6, 2020 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. John Quote Link to post Share on other sites
