Car Forum / Nissan / Nissan Maxima / April 2005transmission flush no-no with high mileage?
Hi all --- i had a little bit of slipping lately (only going uphill, though, between either 1st and 2nd or 2nd and 3rd gears) so i was going to have a transmission fluid power flush done at a garage. i called around to check prices and two places told me they wouldn't do it because it was "not advised to have a flush done on a vehicle with that mileage". then i called the dealership and the service manager told me that they would do it, but they wouldn't recommend it. i've got a 94 gxe at 180k. i've been running on a new transmission since about 90k. any opinions or advice from those here? any would be GREATLY appreciated.

How often have you been changing the tranny fluid since you got the new one? My rebuilt is now about 80K miles old, and in perfect shape ('91 SE, same as your GXE). I do a drain and fill every 20K miles or so. Probably a little sooner than needed, but I want this to last for another 80-120K miles. BTW, I did a tranny flush way back when, and within 2 days, my transmission was shot. Granted, the fluids probably hadn't been changed since the car was new (had '98K at the time), so it was likely a combination of neglect and then a stressful flush that finished it off. Everything I've heard/read is that the flush isn't necessary. A drain and fill is just fine. If you do a drain and fill, make sure they tell you what they find on the drain plug. It's magnetized, and will hopefully collect any fine metal pieces that come off the transmission and keep them from damaging it. My plug is always clean, so I'm feeling good about it's longevity.

Jack It's too late. Changing it won't help. You're going to need a rebuild very soon. > Hi all --- > [quoted text clipped - 11 lines] > > Jack Sounds like your seals are worn out. Bad seals don't allow the fluid pressure to keep the clutch packs engaged fully which does not transmit the rotational power. It feels like a slipping manual clutch but when you rev it up, the pressure builds and then the clutch pack engages, but then slips as the pressure bleeds off. You can pour in a can of that tranny fluid conditioner which has some kind of methyl ethyl ketone chemical that swells the rubber seals. It'll help for awhile but it won't be long until you be standin' still!!! Mine cost me 1500 big US rubles. Chris 90 & 94 GXE's > Sounds like your seals are worn out.

In fact, I think very few economy cars could ever come close to it for durability, reliablility and low cost of ownership. Other people that I know personally, who had the same generation of Sentra, also share my sentiments. I can only hope that Nissan has been able to maintain that standard of quality with the current line of Setras. David > Sounds like your seals are worn out.
