Car Forum / Nissan / Nissan Maxima / January 2006Yikes! Change That Fluid.
I was lookin' thru my records for my 95Max - and it seems - that I have never had the transmission fluid replaced in all those years. So, I started to read up on the topic and saw many allusions to a "power flush" by several names and wondered if it was a worthwhile operation? What exactly does it do that the usual replacement technique ignores? >I was lookin' thru my records for my 95Max - and it seems - that I > have never had the transmission fluid replaced in all those years.

I did three on my 97 Max during the 7 years I owned it, about every 30K miles. The benefit of a flush is that it gets ALL the fluid out, not just what's in the pan. Make sure that if you have it done that they do it with the trans pump inlet, not the trans cooler inlet. It's worth it and it's generally less than $100 (always was for me). Most Nissan dealers offer the service and I'd trust mine over a Sears or a Pep Boys to do something like this as they're gonna recognize a problem in the pan more readily. Not a bad deal to have the engine oil flushed as well. People may balk and bitch about the benefits but the crud I saw come out of my immaculate and routinely maintained car was astonishing. Mileage and acceleration improved after these procedures and fluid consumption dropped. Hell, flush the cooling system as well! Complete the triple play. >>I was lookin' thru my records for my 95Max - and it seems - that I >>have never had the transmission fluid replaced in all those years.

How many miles? To flush it now might actually cause it to fail. > I was lookin' thru my records for my 95Max - and it seems - that I > have never had the transmission fluid replaced in all those years.

Just do a drain and replace to be safe. If the transmission is running fine now, then there is nothing in the clutch packs that really "needs" to be cleaned out. Flushing it can drive junk into them. I'm not saying it will happen, but IMO it's absolutely not a risk to pay extra for.

IF they use the transmission pump inlet, fluid is being moved through the transmission at the same rate as if the car was operating. A proper transmission flush is NOT pressurized beyond the normal operating pressure. >>> I was lookin' thru my records for my 95Max - and it seems - that I >>> have never had the transmission fluid replaced in all those years.

Can you describe what it means then when they claim a "power flush" vs. simple flushing? (I'm honestly asking) Dave – The commonly used A/T term 'flush' isnt accurate; there is no such thing – just normal flow·  – 'Drain' means that 3/4 of the supposed oil is still ol 'degraded tar'… Dangerous· If 'drain' is done 4times (10s idle between) – only then about 80% oil has been changed [depends on tranny – Tranny oil swap must be done 2–30kmiles depending on conditions· DIY.
