833 transmission decoding

[schmuck1]

This question has been thrown out there probably a number of times, but I'm still a novice at this. I'm trying to determine the gear ratio of my 833 transmission. Top # is LM123P9B239775, next is #PP8332698, bottom is #H4 C99129. I know what some of the numbers mean PP=plant 833 trans. 2698 date, but having a hard time finding gear ratio.
Thanks, Guys

Your VIN decodes as a '69 Dart with a 340 (there's an extra "1" in the third position of the VIN you posted).

Here's the likely ratios: Fine-spline V8 (most pre-1971)2.66,1.91,1.39, 1.00

I have a '68 Barracuda with a 360, the OD 4-speed, and 3.23 gears which I love! The lower 1st gear launches really well and the overdrive makes for 1800 RPM at 70 MPH!

Overdrive (mid-1970s and newer)3.09,1.67,1.00,0.73
