It is a V6 LE with the A541E transmission. I recently purchased it with 112, 000 miles on it. Drove it for a couple of weeks and everything worked fine. Then I had the transmission drained and filled at a local shop. No filter change, no flush. Within 2 days I started having trouble. Shifting into drive caused a double engagement about 1 second apart. Next the upshifts were delayed, slow and engaged too hard. Similiar problems followed with downshifts. Now the noises have set in. Grinding vibration in drive when stopped and it is now starting to do it in reverse. There is a New noise which is a consistant growl/ whine that changes with gears. All this has happened over 3 weeks. At this rate I expect the transmission to fail in two more months or less. I checked the fluid level when hot whith engine running and it looks fine. I am not sure if there is anything that can stop or delay the inevitable but I welcome any suggestions.
