I have not yet done 80 MPH with new trans and probably only done it a couple times in my old one. For me, it is not about the quarter, but the quarner

The T-3650 was .68 in 5th
The T-56 is now .62 in 6th

I cannot even tell the difference between the two in RPM's or power. Technically I will gain some better MPG, but will NEVER even notice. I suppose if I traveled across the country in each in exactly the same route and speed, I may save $5.87
