Default Pulley set with Automatic

Anybody installed a light weight pulley set on a 2.2 with an automatic transmission?

Seams as though the biggest gain is the way the car shifts. How does this affect the automatic?

I just want to avoid loosing anything such as: smooth shifting, fuel economy, general drivability.

Installing MrJosh's lightweight pulley really made a huge difference on my 2.5 4EAT. Shifting is still as smooth as before, but when the torque converter unlocks and you downshift, you really feel it! Drivability is much improved. This was one of my first mods and I would recommend it to everyone.

As for fuel economy, had I been driving it normally, it probably would have been the same-- I was too busy stomping on it all the time to really care

Installed a ProECM lightweight set on my 2.5L 4EAT, and the biggest improvement would be how quickly the car climbs through the rev band. It no longer takes forever and a day to get into the power band when downshifting, or just accelerating through traffic. I liken it to installing a lightweight flywheel in a manual transmission car.

Definitely worth it. Especially since the stock crank pulley weighs in at 6.5 lbs or so, and a light weight pulley is around 1 lb, the gains are awesome. Nothing earth shattering, but definitely worth it to try and speed up a 4EAT.

Gas mileage wise, I'm not sure. Didn't see anything huge on differences, though I always seem to have a heavy foot and this doesn't help it.
