1973 L-82 Turbo 400 Emission Questions

[Thomas R.]

The Transmission Controlled Spark soleniod for the Automatic is a part # DR 1997425; my replacement TCS is a DR 1997410 for a manual transmission. Does it make any difference operationally?

Also the L-82 Broadcast Code for the Diverter Valve is GJ was it stamped directly on the Diverter or on a paper sticker? If on a paper sticker any idea of size or color?

Tom,
I'm not sure about about the TCS Question. But the broadcast code is a paper sticker type for the L48 and L 82. The black letters on a white background measure about 1/2 inch. Included a photo.

Don't know the performance difference between the two but do know the 425 is almost impossible to find at least in NOS. Should be able to find a used one.
