Re: 4 speeds
Mario------
I would say that the Borg Warner T-10 was produced on October 5, 1961. From the information provided, I can't tell the ratio.
The Muncie date coding does not look correct to me. However, it MAY be a 1970 model year transmission and the close ratio (M21) variant.In Appreciation of John Hinckley -
Need more Muncie info
Can't help you on the B-W.
What's the part # cast on the top line driver side maincase; ie. 3851325, 3885010, 3925660 or 3925661 ?
Where is the P assembly date located ? Are there 10 splines on the input shaft, and are there none, 1 or 2 circumferential rings.
is the "b" at the end of the P number, or is it located at the start of the 180155 ?
Pics would be preferred, but if you could provide this info, we can go from there.Comment
