Anyone a T56 expert?
I just picked up a T56 for my cobra and im trying to identify what ratios it is.
I was told it was from a VE SS 6lt Commodore. The id tag has been broken off and the sticker peeled off. Sounds a bit dodgey but i dont think it is. The gearbox is the type that has the shifter on a bracket off the back of the box. Does anyone know how to ID it without the tag? Surely they dont make the only id on a removable tag. I know i can work out the raito by rotating it, but it is hard to do that acurately. BTW there is a TUET number printed on the side but i cant quite make it out. It looks like TUET8391 or 8381 but these arent shown on their website. Cheers. |
From the description of the selector it does sound like a Commonwhore gearbox.
|
Yes it is a commondore, but i want to know what ratio. I think all the VE's had the shifter like that which is the same as the TR6060. But i think only the HSV and the W427 had the TR6060.

Maybe call Mal Wood in Warwick - he would know in a minute. Even send him a pic perhaps.

Drop it in 6th gear and count the input vs. output. Here is the chart:

And as Merv suggested www.malwoodauto.com.au/cobra.htm

has it got a speed sensor in it?

Hi Doubledip,
Im not sure. It has a sensor on the passenger side at the rear ( is this it?) and then a sensor towards the front on the driver side (reverse?). Do these boxes have a neutral sensor? http://www.clubcobra.com/photopost/d...0012011321.jpg http://www.clubcobra.com/photopost/d...0012011320.jpg I found a post on another forum stating that this was what is in the VE. Can anyone confirm?

Going on your pics, that is a VE T56.
Reverse light switch on RHS front and VSS at rear. |

Guys know its a T56 and i know is from a VE. What i am trying to confirm is the ratio. It has no tag on it.
|
That is the easy part. Drop it in first, count the input vs. output turns. Do the same in 6th. You'll know what the ratio is real fast. Without a tag, that is the only way to do it.
My guess is it will have a .5 sixth gear ratio, which gives it a 2.66 first according to the chart, since just about all the T56's with that input output spline count have that ratio. |

Is it easier to read after removing all but 26/27 spline count? There is still a 2.97 First with .50 sixth. |
if you know it is a VE, surely the VE ratios are known/published? Call Holden?
|
Well i discovered why i couldnt figure out what it is. It is a TUET8381 which is not listed on the TTC website or any of the other lists floating around.
I emailed TTC a few days ago and got a response last night. The ratio is different to all the boxes on the list: 1st = 3.01 2nd = 2.07 3rd = 1.43 4th = 1.00 5th = 0.84 6th = 0.56 Thanks for the input everyone. |
