Well, surely trans service is overdue. You’ll get a few chicken little’s here that will advise against it. If it’s feels like it’s “banging” when transitioning, it could be slightly prolonged co-engagement going on. Now if you mean a “flare” …where the engine sorta rev’s a little and then the trans grabs, that can be a number of things. Most of them are serviceable by a good trans shop without doom attached to it. I like to do an Auto-Rx treatment before changing the filter and fully exchanging the fluid. It assures that any varnished valve body surfaces are clean. ([www.auto-rx.com](http://www.auto-rx.com)). Transman will be along to give you the authoritative advise soon. ---

I’d ask around for a reputable independent trans shop. Go and ask the guru (typically the owner) to do a road test and let him experience the issue. See what he says. ---

You need to scan the computer for codes. When you feel a harsh downshift (Usually around 30 MPH) there is usually a code set. When you feel that harsh downshift take it directly to a local auto parts store and have them connect their code reader. DO NOT shut off the engine or you could reset a pending code. Hook up the scanner with the engine still running. transman
