[Bob Stoeger]

Hi,
After looking over my trans I noticed it doesn't look the same as Julians trans. would anyone be able to ID my trans by these pictures?
Thanks,
Bob

Hi Bob,

What does the tag that is on the rear cover, at the 5 o'clock position, have stamped on it?

From what I can see of casting marks on the rear cover, it was cast in either '85 or '83. Its difficult to read.

If it is in fact one of the more desirable axles, you have an ideal setup for a rod type shift linkage set-up, as you seem to have the single cross shaft, shift mechanisim.

Cheers,
Scott

Consider changing those knuckle joints to heim joints for a more precise change. Also heat sheild the cables and joints aroud the gearbox end as they will get hot from the exhausts.

 

[Bob Stoeger]

Good advice Malcolm I'll remember that when it comes time to final fit the trans

 

[Frank Catt]

The box looks like a version of the earlier GTD box based on the Reault 30, having a final drive ratio of 3.88, not 3.44 of the R21T box that is most favoured. If so you will be limited in top end speed ---- Frank

 

[BruceA]

Looks like an R30 box. If so, it has the 3.89 final drive, but the added advantage of a 4-spider diff unit. The type of box it is, is engraved on the back of the crownwheel. You will probably see the markings 369 .... whatever .... This indicates a Renault 30 or 20 box. Count the number of spider gears in the diff, if there are 2, its probably a Renault 20, that has a 4.11 diff. I'll check my stash of Renault Bellhousings - the position of the starter was different on the V6's to the 4's.

I don't mean to hi-jack this thread, but does anybody have pics/information on a rod-type linkage for the UN1? I did a search and couldn't find anything, thanks!

Here is a pic of a rod change set up on a GTD.

As I'm in the middle of collecting parts for a UN1 rod-shift mechanism for my Tornado, I've finally got my head around what I need. Tornado sell a complete system, as shown, but I plan to use the previously mentioned GTD design, with the gear-lever end similar to what Ultima use.

Hope this all helps
Regards
Andy

Thanks for all the pics and info guys - keep it coming!

Scott, this isn't going in a GT40, I'm building a 914 with a Mustang 5.0 and UN1...

Regds,

Hi Julian I have found this old post an wonder if the standard set up is still available from GTD especially the shifter gate.Any help would be appreciated John

Hi John,

I'm afraid GTD went out of business many years ago! Tornado sports cars or Southern GT would be your best bet at this point in time.

Kind regards,
Julian

 

[John]

Thanks Julian,It turns out that Southern GT is no more but think AK sports cars seem to have taken them over, so I contacted them and they can offer a linkage and gear lever and gate and have spoken to Tornado too.
Both look possible as a starting point, but of course my set up is as Renault Alpine A310 and GTA,so would need some modifications.I know the GTD shift gate looked exactly what I wanted as the positions for the gears is exactly as mine is at present with the awful cable change.
I am trying to buy a complete GTA set up if this comes off it could be adapted and also won't be the eye watering cost of the Other two especially the AK version.
Thanks again for your reply
John

Hi John,

Sounds like you've got an interesting project. It's a long time since I fabricated my rod change (this thread is 17 years old!) & things have probably moved on since.

However I think you will struggle to find a 'bolt-on' solution & whichever way you go you may need to make some modifications to suit your application.

Good luck with your project,
Julian
