I was updating my website and found that there are actually 6 different part numbers for the T56 Magnum

-Part# TUET11009 hydraulic clutch 
-Part# TUET11010 mechanical clutch 
2.66 1st 
1.78 2nd 
1.30 3rd 
1.00 4th 
0.80 5th 
0.63 6th 
2.90 Reverse

-Part# TUET11012 hydraulic clutch 
-Part# TUET11011 mechanical clutch 
2.97 1st 
2.10 2nd 
1.46 3rd 
1.00 4th 
0.74 5th 
0.50 6th 
2.90 Reverse

-Part# TUET16885 hydraulic clutch 
-Part# TUET16884 mechanical clutch 
2.97 1st 
2.10 2nd 
1.46 3rd 
1.00 4th 
0.80 5th 
0.63 6th 
2.90 Reverse

The 2.97 1st and 0.74 5th, 0.50 6th will eventually be phased out so get one while you still can!
