1.8T vs 2.8 manual tranny !

[Kevin Boykin]

What the final ratio of both trannies ? (3.89 or 4.11 or else )
Are they the same ? 
what is the differencies ?

Can a 1.8T tranny is tuff enought to bolt on a 3.6 V8 ?

thanks

Hello Denis,

Here are the ratios for a 1999 1.8t manual vs. 2.8 manual

1.8t:

Manual (Automatic)
1st:   3.778:1 (3.665:1)
2nd:  2.176:1 (1.999:1)
3rd:   1.429:1 (1.407:1)
4th:   1.029:1 (1.000:1)
5th:   0.838:1 (0.742:1)
Rev:  3.444:1 (4.096:1)
Final: 3.889:1 (3.730:1) 

2.8:

Manual (Automatic)
1st:   3.500:1 (3.665:1)
2nd:  1.944:1 (1.999:1)
3rd:   1.300:1 (1.407:1)
4th:   0.943:1 (1.000:1)
5th:   0.789:1 (0.742:1)
Rev:  3.444:1 (4.096:1)
Final: 3.889:1 (3.730:1) 

As far as the durability of the 1.8t tranny, I can't really say.  Supposedly they are very tough - there are a few A4 guys out there running at least 300 crank horsepower that don't have problems with the 1.8t tranny.  I'm at about 235hp/260ft-lbs crank power on mine and it's at 71k miles no problems at all.  There are a few guys running much more power than that, and as far as I know I haven't heard of much breakage.

Regards,

kevin
