Okay. Tranny fluid change was successful today. Unfortunately I still have a bit of a problem. The shifting has improved, and when giving light to moderate gas it is perfect. But when I hit the gas fairly hard, the tranny let's the engine rev quite high (i suppose this is normal) but then clunks into the next gear. It is especially bad when I am already moving at a good clip and then hit the gas hard, say when merging. Anyone have any ideas where I should look for problems next?
