Another T5 Bites The Dust

[G6ET8U]

If you went for the OEM T56 from Ford, 1st gear is 12% taller than the 1st gear in the T5...

Have been running my T5 for over 80,000 km at just over 250rwkw and it still feels like it did the day it was new,.... like an absolute piece of schitt!

The old grey fergy tractor had a smoother gearchange.

Found this on a particular auction site that we arent allowed to post links to .....the item number is.....  4637722780...a brand new t5 from a BA xr8 for $880 buy it now price...might be a goer. Dont know how different the ratios/bellhousing etc is though...

no T5 in the XR8 I think. Its a different box to that found in a T or n/a XR6. I think it may have some relationship with the 5 sp in the late model mustangs.

...PS hideous, I have not driven a XR6 T with a T56, however I have driven a number of cars with 6 speed boxes and I dont like having a first gear that revs out so quick ...... good example 350Z.

Do the math. Most of the jap stuff runs a 3.5 or so first gear. You can run a T56 with the same first gear you have now, or a taller one. (as stated previously). I cannot understand how someone can have such a narrow, uninformed view on a subject, with no regard for the facts. Imagine the flaming if someone got on here and said turbos are crap, they hate them, they have too much lag, but then admitted to only having driven a turbo charade? Do your homework. Ben.

I think that its a Tremec TR3650. I have heard that they don't fit straight behind the six but not sure how much effort is required to make it fit

Does anyone have a comparison of the various gear ratios between the T5 and T56 (as fitted to the XR6T). I am about to step out of my current T and am leaning towards the BF with the T56. I do a lot of towing and in particular, towing and takeoffs on hills. Would like to know the different gear ratios, particularly 1st gear comparison and whether the diff is the same in the BA T5 as the BF T56.

I have tried a search in this forum but no luck.

yes I did that with the tune hence the gear box went seya did you have the 3.46 and then changed to the 3.7

My case is a bit different, as I've had 2 completely different 6-speeds from Mal Wood with different ratios and internal strengths.

I had a 6-speed with the 3.46 diff first.

That 6-speed had ratios 2.97;2.07;1.43;1;0.8;0.62

Those ratios worked very well as a T5 replacement, and keeping the 3.46 diff.

I then updgraded the diff from 3.46 to 3.73, and the car was far more flexible in traffic.

I then told Mal that I was upgrading to a Nizpro Stage 5 (500rwkw), and he suggested an even stronger box, that has a fully splined mainshaft for 5& 6th gears. That box has the identical gear ratios as Ford now use (I.e 2.66;1.78;1.3;1;0.8 ;0.62). Mal had that box in his turbo ute. I drove that and found that the 2.66 first gear with the 3.46 diff was not real good getting off the line, and it wouldn't be good in stop/start traffic, and that a 3.73 is a much better solution. Hence Ford chose the 3.73 for the T.

When my 2nd T56 gearbox went in I changed the diff over to the 4.10. I'm considering running higher profile tyres in the rear to get back some gearing.

fyi 1st gear ratio in the T5 is 2.95, so almost identical to the Ford T56, however diff used with T56 is 3.73, not 3.46 as with the BA T5.

I am sure you don't even need to look this stuff up Brian, you just have it all in your head don't you!

Thanks for that.

[XR6ISM]

Thanks for the info Brian, Ill have to go through it all again.

Does anybody know if there is a difference in times at the creek between the 5 and 6 speed. From my understand, what you guys say is that the gearing would be relatively unchanged. So is it correct to assume the time should be the same also?

Further, is it correct to assume that 5th and 6th are overdrive gears?

Not to sure when it comes to gear boxes hence why I ask the questions.

4th is still a 1:1
