1987 Acura Integra Automatic, 160k
I have been noticing - mostly for every start (there are a few in between that did not have that sound).
When starting, a loud sound (some what unbearable) heard and was hesitant and then the engine starts. Once started it runs fine. It is not the usual sound that the ignition makes when going bad.
What seems to be the issue?
Right after I drained and filled AT fluid, it heard the first time. I have been doing AT fluid since nearly 10yrs ago with Honda fluid. I only did drain and fill and it went smoothly. In 2007, the tranny was replaced. After starting, the car runs smoothly - it is only when starting or just before engine try to start. Batt and alternator tests fine.
It hardly did it today - I might have once heard a girding sound just before starting.
