I bought an original owner 2006 Lucerne last year. Only about 5k miles put on it since I got it, with near 80k miles on it now (3800 motor.) When I got it, I did several drain and fills with Dex VI. Put a little Lubeguard red as well. (I know some of you say a waste/don't do it with Dex VII) The car/trans was running fine, probably original fluid, and the fluid was reasonable looking.
My daughter had the car at college and I just got it back to daily drive again. On decel to stop or near stop, if I get back on the throttle quick or hard, the car will bang into gear. My best guess is that the trans isn't done downshifting cleanly into 1st (?)
I had read and debated the accumulator mod, which I'm ready to do, but wonder if anyone has additional suggestions before I just do that one part of the Transgo kit alone. The car seems to shift pretty near perfect and smooth on any variety of throttle position otherwise.
