Transmissions marked "**" have a special (better for performance) valve body, plate, 1-2 servo, 3-4 servo, 2-3 intermediate servo, and governor.
These codes can be found on the passenger side of the transmission near the output shaft. Sometimes they are hard to read due to the catalytic convertor getting in the way.
The valve body itself will have the first two letters painted on it. Be careful because the paint comes off easily. The special valve bodies usually have a purple strip on them also.
