All signs had been pointing to the torque converter, even mechanics saying it was bad. Has been hesitating for the last hear or so, especially when its cold. Last week the gf's alternator went out, and I had to replace it. (HELL of a job) Once it was replaced I had to go out of town for a few days for work. When I got back I started driving her car (cause mine went out while I was picking hers up from napa, my luck) and I noticed it was running 100%, no sluggishness, no hesitation. I said something to her about it, and she told me she noticed it from the getgo, but didnt want to say anything to see if I noticed it, and so as not to jinx it.

ANyone have any clues as to what was going on and what I did to fix it?????

My tranny used to do that -- especially with the A/C running. I installed a grounding kit and that helped to eliminate the lag, but I suspect that the change was more a result of the ECU being reset due to the battery being disconnected for nearly an hour.

Your ECU was definitely reset in the process of replacing your alternator. However, if your previous one was not outputting a clean, strong voltage, then that alone can account for the fact that your ECU & PCM were not functioning properly. These tiny computers are what determine when and how to shift your tranny.

As a general rule, sensitive electronics rely on having a good electrical connection in your car and many problems can be traced to either poor connections or poor sources of electricity.

...which is why a good grounding kit can help improve upon existing electrical connections.
