Re: (pdiggitydogg)
In some cases trying to ID a B-series tranny is not always possible from it's external markings. So how can you tell?
This is what i have found to be the easiest method of doing so.
First you have to start off by taking the outer casing off. Fortunetly we already have a how to on that subject thanks to Plan B: How to: Take Apart a Transmission
Now that you have it apart. You can either go a step further and remove all the internals to be able to count every gear, or just get a tooth count on the final drive gear, it's opposing gear located on the counter shaft, and the upper most gears on both the counter and main shafts to calculate the transmissions 5th and final drive gear ratios.
Once you have counted how many teeth are on each gear, you need to divide the number of teeth on the counter shaft, by the number of teeth on the main shaft to find the gear ratio. I'll give you an example using the transmission pictured. **
There are 25 teeth on the upper most counter shaft gear and 35 teeth on it's opposing gear located on the main shaft. If you divide 25 into 35, you come out with a .7142857 (.714) ratio, which is the 94+ LS transmission's 5th gear ratio.
Now using the same method, you can find the FD ratio by counting the teeth of the final drive gear, and then dividing that by the number of teeth of it's opposing gear located on the counter shaft, which would be 64 / 15 = 4.26666666 (4.266). The 94+ LS transmission's final drive ratio.
Here is a list of B series tranny gear ratios for reference purposes:

Well that's about all there is to it. Hope this is helpful to some of you...
