'99 military 4l80e w p/brake drum...

[stezloco]

does anybody know if the military boxes with the parkbrake drum on rear of t/box are an overdrive box or a straight thro 1:1 ratio top gear??...is this basically the civvy box? are they the same? ive found a '99 4l80e (so the bloke says) ex military gbox for sale and might buy it and fit it to cure my leaking casing problem...are there any strength improvements to the g/box or the t/box? and do you think it will fit ? i can do away with the cables running to the rear axles and 'disconnect the linkage....? any info at all would be appreciated....

All of the 4L80-E automatics are electronically controlled. So, if there's a large multi-pin electrical connector at the rear of the pan (above the lip) and two speed sensors located on the bellhousing, it's likely a 4L80-E with overdrive and lockup torque converter.
