What kind of huge difference? My 2003.0 tranny seems fine. I would not know what to do to make it better.

Re: Please Help Transmission Problems

See my post about my experience with a loaner G being better than mine.

My early 2003 seems to shift soft and have little pickup form a stop. The 2003.5 I was loaned from the dealer has a very snappy shift and great pickup on the low end. Hopefully they simply changed the ECM programming and I can get mine re-flashed at the dealer with a later program. If not, then the 2003.5 has some significant different engine/tranny or computer issues.

I will be heading to my dealer soon to have them address this and will keep all posted.

Re: Please Help Transmission Problems

I have a June build 2003. I like the way my transmission drives. Very positive but with very refined and smooth shifts. One observation that surprised me - the torque convertor does not seem to lock up at speeds below 35 m.p.h. or so. If I am driving along at 30 m.p.h. and give it a little more gas, the car will stay in the same gear but the r.p.m.s will increase. This makes things smooth but is not very efficient. I wonder if this relates to the gas milage being a little on the low side? I have previously owned only one a/t car in my life (a T-Bird with the AOD) and it would lock up at any speed above about 15 m.p.h.
