Default Changing gears

4I have been having trouble selecting 1st and 2nd gears especially when going slow in traffic so I am about to bite the bullit and buy a sequential gear shifter that will stop me selecting the wrong gears. Does anyone have any fores or againsts about asequential shifter.
Cheers,
Bryan

Bryan, what do you think is the reason for the difficulty in selecting those gears? Is it the shifter, synchros, clutch, or something else entirely?
I'd hate you to invest significant cash on a replacement shifter for the problem to remain.

I reckon it would be the coolest thing in the world to have a dog gear sequential trans with a high rpm motor and a strain gauge shifter..!

Default Shifting gears

Craig,
I have a Hurst shifter It's as old as the car shifting a super T10 and the H gate has has got vague and I'm missing gears and I'm thinking with no shift gate to wory about it will be easier.
Cheers,
Bryan

In city driving, there are a lot of times you want to go from 4th to neutral, or first. With a sequential shifter, you'll have to go up and down the gears to get there.

I would start by installing a new standard pattern shifter.

I agree with Bob, Bryan. A new Hurst unit would be the most cost effective and considering the years of service the current one has given it is improbable you would be able to out live a replacement unit.

The point about sequential requiring a complete transition up through all intervening gears and down through all gears to get to your target gear from where you are can get old very quickly. The other thing worth considering is a new Hurst shifter, properly installed and adjusted, is sort of the gold standard for shifters — and it is reasonably priced.

Hi Bryan, my 2c worth. If your having issues with shift I'd suggest doing 2 things first with your current set up. Firstly if its not selecting gears nicely it means (assuming the box is fine) that either the selector arms are worn and/or need adjusting and your shifter needs a service. Like all things shifters need servicing to bring them back to ultimate performance. Unless your shifter is in good order and the linkages set without slop and accurate on the selectors it won't find gears whether its new or old.

Sounds to me your thinking about buying a renegate shifter for your t10. I think Tomcat on the forum has one on his top loader and likes it. I spent a bomb on one and then spent more trying to make it work properly on my Jerico box and after multiple attempts its lying in the bushes somewhere behind Wakefield Park being treated by the elements with the contempt it deserves. It's rubbish.

As far as driving one in city traffic it's like anything you adapt. My Daytona has a sequential box in it and its not my preference in traffic but then the car is not meant to be driven in traffic so it's all relative.

Before outweighing the funds buying a new shifter with no better outcome get someone who knows how to set up a manual 4 speed trans, make sure your shifter rods are rose jointed and no slop, send your shifter to someone who knows how to service them and I reckon you'll be more than happy.

Matt

Bryan,
I had my Hurst shifter (and Toploader) rebuilt by David Kee's Australian agent in Adelaide. As far as I can tell (as it's not in the car yet) he did a great job....it shifts with the feel of a 303 rifle bolt.
Cheers,
Glen

You guys with auto's, really should look at a paddle shift setup like Gav has.

You might just be better off rebuilding the old shifter Bryan or sourcing a replacement. Like any part that sees a lot of work they wear out.

I went right through and rebuilt the stock shifter in a mates XY GT. Taking all the play out of it with the correct shims etc and adjusting it correctly He couldn't believe how much better it shifted. The wear happens gradually and you don't realize how bad it's getting till it gets really bad.

Each section of the linkage where you can reduce free play will improve the shift. The rod type shifters used on your T10 and Toploaders can be improved further by using spherical rod ends where the shift rods attach to the levers on the box. These are areas that typically wear as they see little lubrication and are exposed to the elements.

Cheers

As Mike suggests this is what I did with my 4 speed. Free play slop is your enemy with this set up.

PS that Jerico box with dual pumps for trans and diff coolers will be for sale early next year for anyone interested. Probably a bit much for most cobra guys unless used for racing but you never know. Street driven it'd suck pretty hard unless you know how to drive a dog box well.
