Personally ,
I think the 2004R has great gear ratios,much better than a TH350 or a TH400.

Powerglide 1.76 1.00 1.76
TH350 2.52 1.52 1.00 1.93
TH400 2.48 1.48 1.00 2.00
200r4 2.74 1.57 1.00 0.67 2.07
700r4 3.06 1.62 1.00 0.70 2.29
4L60E 3.06 1.62 1.00 0.70 2.29
4L80E 2.48 1.48 1.00 0.75 2.08


I am interested in why the gear ratios are worse in a 2004R?

I agree about the 7004R,lousy gear spacing.
