I was told by a 'quickie' oil change place that I needed a flush service with my oil change (I did not do it at that time). I took my truck to LaCar Porte for some minor maintenance (including oil change) and mentioned the flush recommendation and also asked them to see if I needed transmission service (I couldn't remember last time i had that done). LaCar Porte was very honest with me and told me, not only that I didn't need the tranny service, but that they didn't recommend the 'flush' service on the oil change. I will not take my truck anywhere else from now on.
