2003 Buick Park Avenue.
Question Here: The Transmission is shifting goofy.. At times it will shift real smooth & then it will shift real hard.. What could cause that?? I had the dealer do a fluid flush.. I wanted a fluid & Filter change , BUT They said no You want a Flush.. Did I do wrong in doing that too ???
Answer: No, this flush is a good thing to do. Some customers get the filter change and the flush. Just doing a filter change only replaces 4-5 quarts of fluid, because all you are doing is removing the pan. The flush removes ALL fluid, about 12 quarts. If the power train computer has not had a scan for codes, I would suggest that.
There may be a code stored related to the pressure control solenoid. You may have a problem with this solenoid since the problem comes and goes. Could also have a valve body problem. Sticking valves or dirt in the valve body will cause valves to stick and give odd shifting problems.
What Is Wire On Strut?
Question: What is the wire for going to the Front Struts on a 1995 Buick Part Ave Ultra?
Answer: The wire going to the top of the strut is for the electronic controlled suspension. It uses a damper- solenoid to give a quicker response to road conditions than a regular strut / shock.
