I changed the fluid and filter at approximately 6K miles ago. It looks great no contamination etc. I feel it has to be a problem in the shifting between reverse and drive. I have read about a spring, that I believe to be a possible culprit. They talked about it breaking. The import transmission manual in the trouble shooting section I found doesn't mention anything about this sort of problem, but this hesitation has been an issue. I just hope it hangs together unitl I can find the solution, and it doesn't disintegrate.
