My 2000 SL1 has 167,000 miles on it. For the last 100,000 miles, the automatic transmission has acted funny intermittently.

When driving in stop and go traffic all of a sudden the transmission will quit shifting. The problem will persist until I pull over, turn off the car, and restart. Then it usually works fine again for a while.

The other problem occurs when shifting into reverse. When the car is warm and I shift into reverse the transmission clunks hard into reverse. A long time ago I put some transmission treatment/conditioner in and backed the car up to a tree and let it run in reverse for 15 minutes. It may have helped some, but not completely.

I've changed the filter and fluid a couple times and the fluid has never smelled burnt.

Has anyone had these same problems? Any solutions/ideas?

I'm not going to rebuild the transmission yet because it works fine 99.9% of the time.

 

i have exactly the same problems and have also changed atf and filter twice. im thinking about getting a rebuilt shift body. anyone give us some help?
