I have a 97 trans in my 94. Deep sump pan w/ drain, 97 filter, JMOD and aux cooler w/ Merc V fluid and a DD converter.
It shifts out nice and firm just as it should. That's not the issue. When I go to pass someone, or get on the interstate it doesn't downshift as 'snappy' as it used to. It will rev up for about a second and then catch and go. The fluid is full and only about a year old. I'm not sure whats going on. Any ideas?
