So the first gear is lower in the th350 than the 4L60E?

LT-x7

No,
TH350=2.52
4L60e=3.06

No T56?

that was all i found listed ,
and of note a higher number means a lower gear ,

this is why the 4L60e launches so well. that huge first gear. its also why you dont need big gears in your auto!

added to original list

PBA

There were Super T-10's in the early to late 1970's with gear ratios of
2.43 1.61 1.23 1.00 Close ratio
2.64 1.75 1.33 1.00 Wide ratio
both were excellent for street & drag racing.
