T5 Gear Stick Length?

[ChimpOnGas]

Hi chaps,

Can someone confirm the length of the TVR gear stick as it dictates what S-10 short throw shifter kit I buy for my S-10 gearbox mod.

http://www.ebay.co.uk/itm/361389618264?_trksid=p20...

Or

http://www.ebay.co.uk/itm/281798332967?_trksid=p20...

This is what the seller says about stick length when selecting the right S-10 short throw shifter kit from him...

"Shifter throw length - VERY IMPORTANT: Shifters are simple levers, formed by the stick and stub - the overall length and fulcrum height determine the leverage ratio. Shifter throw is the gear-to-gear distance at the knob, determined by the internal transmission motion and shifter leverage ratio. As such, achieving a desired throw requires consideration of both the stick and stub - ie the stick length, and the fulcrum height of the stub. In a custom application there is no point in comparing the base against an OE unit if you are changing the stick length. To get a good throw, you have to choose the stick and base together as a set. This base model has a 3.03" fulcrum height, ideal for 10-12" stick length. Longer or shorter sticks require one of the other fulcrum options mentioned below (email to request); no one else offers these options but we do because that is the only way you can get the right throw length for whatever stick you choose."

Apparently the stick length measurement the seller needs should be taken from the bottom of the two mounting holes at the base of the stick to the top of the knob threads (so not exactly the stick's total vertical length).

Many thanks to anyone who can confirm this measurement.

Dave, would you like the measurement from the top of the gear-knob to the lower pivot plate, as per the pic below?



P.S. I know the gear-knob itself is not present in this pic

Mine measures 10"

Hope this helps,

Thanks Ged,

I think the measurement the quick shift seller is asking for is intended for someone that already has their gear stick coming directly out of the T5 top plate (IE no TVR linkage).

So for us that translates to... from the top of the knob threads on the TVR stick to the bottom of the two mounting holes at the base of the original positioned stubby lever where TVR connected the rear end of their linkage.



I hope this makes sense??

Effectively you've got to draw an imaginary horizontal line from the bottom of the two mounting holes at the base of the original positioned stubby lever, to the TVR gear stick. If you mark the stick there you can then take the measurement between the top of the knob threads and your mark on the TVR gear stick.

Here's what I'm trying to explain (badly) in a picture which should be far easier to understand than all my old waffle



The final correct measurement will of course be less than your 10" but as we all know... size doesn't matter

Except when you're trying to buy the correct S-10 quick shift kit that is

This was my solution, I remade the lever from ali and used a mk4 golf drop link to give me a rubber bush to help with vibration & heat. I left plenty of thread to adjust it at both ends.

Nice job there Andy

Phrases you never thought you'd use no. 1...

That bush is a really good idea!

Bump,

Can you help with this measurement Ged?

Thanks in advance, Dave.

For you that translates into a measurement in the order of 6 inches.

Thanks Ged,

To be honest I'm quite surprised it comes out at just 6".

I was sure you'd come back to me with around an 7" to 8" measurement given your first measurement taken from the ball end was 10"?



Sorry to ask again but according to the seller of the Hurst S-10 quick shift kit this measurement is absolutely critical, is the 6" an estimate or did you take direct measurement mate?

Just keen to make 100% sure I don't order the wrong thing as the quick shift kit needs to be configured to my exact measurements and will be coming all the way from the US.

If you could drop a tape measure on it again and give me an exact metric figure in mm I'd really appreciate it.

Many thanks, Dave.

Dave, the difference in the length without the gearknob is 1.5", so that takes you to 8.5".
The distance to the bottom of the lower hole is in the order of 2.5", leaving 6".

Of course, the accuracy between cars depends on the accuracy of TVRs manufacturing of the gear stick.

I won't be able to re-measure until the weekend, as I work away during the week.

Ah Ok, many thanks I'm very grateful for your help Ged.

So your initial 10" measurement was from the top of the gear knob not the top of the thread?

Then the distance from the bottom of the bottom hole to the tip of the ball end is 2.5".

Giving.... 10 - 1.5 - 2.5 = 6

I get it now.

Many thanks for all your help, I'll tell the seller of the quick shift kit to work on the following...

[BoostedChim]

Dave, how are you going to attach the shifter mech to the gear lever? Could you not adjust the height there?

Ah, that's a really good point Andy

Obviously I need to move the stick position to the right of the gearbox centre line somehow anyway, actually can you confirm by how much exactly?



I like your fabricated offset adapter with it's clever rubber bush arrangement and I guess it also gives you a level of stick length adjustment too?

Perhaps I could be cheeky and ask you to make me a copy?

Seriously though, any help with the offset measurement would be gratefully received.

Here’s a picture of the g8ape gear lever adapter used by stevesprint when he converted his Griff to a T5.

To me it looks like a perfect "off the shelf part" but I'm damned if I can find one for sale anywhere online?



You are well ahead of me on this S-10 mod Andy, so any help you can give me is much appreciated

Many thanks Dave.

Paul Cangialosi just came back to my shifter query email and he's telling me the quick shifter kits I've been looking at for the S-10 may not suit given my 6" stick measurement.

This is because the T5 with the S-10 tail housing was fitted to trucks with really long gear levers, so the S-10 quick shifter kits are typically designed with this long lever in mind.

On our already super short 6" TVR stick length one of the S-10 quick shift kits could easily result in a shift throw that's way to short.

Paul advised me to simply search out a shifter for a Camaro or Firebird, but I'm now wondering if the TVR one can simply be used on the S-10 tail housing

TBH I thought the bolt patterns were different, but perhaps I'm wrong on this?

Perhaps this is what I need after all?

Yeah I just re-used my orginal one. You could always swap it later to an aftermarket one if you wanted less throw. There are two bolt patterns Ford and Chevy, I'm pretty sure ours are the Chevy type. On the Ford ones the two front bolts are further from the shifter.

When I emailed g8ape he didn't have any gear lever adapters in stock, he gets them made up 5 at a time. Try him again now, you might have more luck. From one of those threads I think it was g8ape who said the adapter moves the stick 58mm to the right and 10mm back.

If g8ape hasn't got any instock let me know, I might be able to make another. My wife is due to give birth any day now so I don't want to promise something I might not be able to deliver for a while.

Thanks mate, I've sent g8ape a PM, lets see what he comes back with.

Congratulation on your new addition, wishing you and your good lady a safe and successful birth

Give me a week or so and I'll pop up and you can measure mine if you wish?

Cheers Phil,

The way I see it neither the centre line of the gearbox or the amount of offset needed will change from the current setup on the TVR linkage.

Surely therefore it wouldn't be that hard to just adapt the existing TVR dogleg bracket?



The existing TVR dogleg bracket just needs two locating holes in the correct place to bolt it up to the shifter, potentially you wouldn't even need to unbolt the original TVR gear lever from it?



Perhaps I'm over simplifying it as I'm sure Andy wouldn't have gone to all the trouble of fabricating his rubber bush bracket if the TVR one could have been simply adapted?
