After an extensive 1 second search on Google, I clicked on the first link it provided, which happens to be the manufacturers home page.

What do you know, complete information including gear ratios....

That's why we love Unit....Straight to the point with only a minor after taste of the sarcasism that was just swallowed, with just a hint of bs.

Re: trans gear ratios
 

Yes I also found that info but it shows that both Trans have about the same gear ratios yet I noted a dermatic change in pull so could ford t45 have different ratio's then listed.

Re: trans gear ratios
 

Are you talking about 5th gear or every gear where it doesn't seem to pull as hard?

Re: trans gear ratios
 

Good point....

Re: trans gear ratios
 

no only the first three gears. I am considering going back to 3650 or to a t56 I heard that 3650's don't hold up as well..

Re: trans gear ratios
 

3650's are MUCH better than a weak T-45. If you have the cash flow, get the T-56 and be done with it. No question about it. T-56 all the way.

If you go with a T-56 definitely change the rear gears out for something steeper because they have a tall 1st gear. I like my 4.10s with the T-56.
