Transmisson Identification

[IH/Nav43yr]

Does anyone have information on the old borg warner automatic transmissons that were used in the 1969 to 1971 International light line? Looking for the difference between the t-49 and the t-409. I have looked through old IH fleet service news letters and the old slm letters for 1969 and 1970 and all they tell me was the t-409 was used behind the v-392. Seems I can recall that it was either the t-409 or either the (t-407 chryselr transmisson) used an extra pair of discs in the clutch pack when mated behind the v-392. The borg warner # for the t-409 was as2-11a and International's part # was 384213c91.
Just looking for a little enlightment.

Don't have a lot of info but I've been tinkering with my bw11 off and on for a year or so..I can say that the t-39 that hooks to the 232/304 engines have a different number of output splines that the bw11 that attached to the big block IH's...but I forget the numbers..it's something like 19 spline to 232/304 and 25 spline to the bigger engines...
