What's up everyone? Just bought my first Impala a few weeks ago. 2001 LS with 3.8 liter and only 22,000 original miles. I absolutely love the car. Drives and looks like it just came off the showroom floor, with exception to the trans. From what I read online seems like this is a very common problem, although not with such low mileage. Drives perfect in the morning, but after it warms up it has a slight slip between gear changes, until the PCM commands full line pressure. No check engine light and I haven't had it scanned, but I would assume a P1811 code is hiding in there somewhere. I was thinking of installing the transgo kit myself to see if it helps. With only 22k miles, I have no service history and for all I know it could be the original trans fluid and filter in there. Still looks red and doesn't smell burnt. I plan on dropping the pan and changing the fluid and filter along with the transgo kit and see what happens. What are your recommendations? Thanks everyone!
