VIII looking for 8s
Our family has inherited my grandma's LeSabre. It is a 99 with 71K miles. The transmission is the 4T65E. From the day we brought it home, it has had a slight torque converter shudder that seems to surface when the transmission is warmed up and the torque converter is going into lock. In the recent past couple weeks, it seemed to get more harsh and even shifting gears seemed a little shuddery. Imagine 1-shudder-2-3-shudder-Overdrive.
So, no more procrastination I thought.....time for a pan and filter drop with some fresh fluid. All went well, got it put back together and everything was fine for a day except for the fact that it still has the shudder. Well, I am sitting at a stoplight on the way home from work. The light turns greena nd I give it moderate throttle. Shadadadadadada! This was immediately with throttle from a dead stop. Imagine the front tires wheel-hopping like an IRS car but instead this was the transmission doing this awful action. It does it whenever the transmission is warmed up and "moderate" throttle is applied. If I very easily get into the throttle it doesn't do it.
So, what the hell is going on with this car? And to be honest, the fluid looked dirty on the stick again too which is kind of weird.
