I ran a search about this and I didn't find exactly what I was looking for although I did get some general ideas. While driving my 92 Ex sedan a/t in any gear it shudders rapidly in the 4000-5000 rpm range. This only happens if I try to gun it or exceed 120-130kph. This seems to make driving a hazard mostly because passing is a pain and I seem to only narrowly escape other drivers and their stupidity. I put in some transformer a/t and it helped for 1 day, should I just get a tranny flush done? Any help would be appreciated.
