Hello people! I have a strange troubling problem with my TL transmission. When I start and drive my car everything is fine for the first half hour, then I start to have issues in two separates situations. First when I come to a relatively abrupt stop (not skidding but say stop in 50ft from 30 mph) the car feels like its manually downshifting and just before a complete stop I can feel the trans "let go" and when I perform a gradual stop with no urgency its all smooth. The problem for me is it seems the trans should not still be trying to drive just before a complete stop. Now the other scenario is when I'm waiting at a light and it turns green, during the time it takes for me to take my foot off the brake and press the gas, I feel what seems to be the car riding on gears like it was a manual trans in first gear but not quite getting enough pedal to avoid a stall. So if you can imagine a manual not getting the gas, the car will buck and stall when the clutch is released so for comparison we will call this a 10 on a scale of 1-10. Whats happening to me is a 1 or 2 on that same scale so no chance of a stall but I get a light bucking/vibration just before I apply the gas.
Now, as for the pertinent details its a 2007 TL AT with 185k miles on it and when the problem started I did a staggered 3x3 fluid change and have started to change the pressure switches but due to my schedule and lack of 07' reference material, I only have managed to replace one switch because its like exploratory surgery with unforeseen obstacles like the discovery of a broken upper trans mount that has a connecting arm that is blocking my access to the pressure switch. I'm in the process of ordering a new mount and will wait for that so I can do both at the same time.
Any ideas as to what the trans problem could be? Also just to note the trans is fine in all other situations. Pic below is the drain plug after 1st drain and fill.
Thanks After 1st drain and fill.
Update- I finally replaced the other two pressure switches and the symptoms are greatly reduced. Looking back this job was difficult because there was very little info on the 07' from a procedure standpoint. Maybe I'll post something in the near future.
