Why is AT less efficient?

I located the shop manual and noted that I can override the TC engagement through manually engaging 1 or both of the 2 TC lockup sensors via 5V power. Judging by the schematics, it may bypass the VSS and TPS to make the final decision to lock up through the switch override -- I'd just have to be mindful of speeds and coolant temps to prevent further damage to the trans. Of the 3 settings of full, partial, or zero lockup, one sensor allows partial, and the other engages full and uses the Hill/Fuzzy-Logic adaptive computer for shifting (argh). So, during the colder months, perhaps 2 toggles could manually engage these at lower TPS settings once the speed allows. Purely theory.

I'll tell ya, that 50-page section on the automatic transmission looks more complicated than open-heart surgery. Sheesh.

If you're stuck with an auto, I reccommend finding a shop manual that describes exactly what parameters the transmission requires. Further inspection could perhaps find a way to take control of that vicious dictator: the Transmission Control Module.

Wow thanks for all the responces! I could swap in a Camero 6 speed transmission. I've had two 5 speed manual cars before. On both, I notice if I short shift, I can get better than the EPA highway milage, in the city. I have a 700r4 transmission in my caprice, I would have trade in the newer electrically controlled one and program differnt shift points.

A camaro 6 speed will cost you more than a metro

I googled "camaro 6th speed manual gear ratios" and found this :

1996 CHEVROLET CAMARO
http://www.media.gm.com/ca/gm/en/pro...996Camaro.html

(Paraphrased from URL)
TRANSMISSION : 6-speed manual w/overdrive
Gear Ratios:
1st 2.66
2nd 1.78
3rd 1.30
4th 1.00
5th 0.74
6th 0.50
Reverse 2.90

and with my gear ratio and tire size, at 75 MPH the engine would be turning 1500 RPM 50 MPH is 1000 RPM. With the low end torque of a 5.7 liter engine, I'd have no problem If I want a little passing power, I could just down shift.
