My 2004 sedan now has 110K on it and I think it is about time to get the tranny serviced. Anyone out there have any pros/cons of taking it to AAMCO for the power flush or power flush plus? Thanks.

Has your trans ever been serviced before? If yes, do a drain and fill in each of the next three oil changes and you will be good. If not, I recommend the same. As your trans wears it uses wear material that is in the fluid for friction. If you remove all the wear materials at once your trans can slip and then you have to rebuild or replace it. As for the flush, thus replaces all fluid except for what is the torque converter. As stated before, too much new fluid can be a bad thing. Also, if there are large wear particals in the fluid they might be forced into a port and clog it. This will starve part of the trans for fluid and burn it up. You guesed it, rebuilt or new trans.

If you can change your own oil you can change your trans fluid. There is a video DIY on here showing the steps. I use castrol import multi vehicle trans fluid with good success. 163k miles and counting.

 

Personally I wouldn't use AAMCO for any service but that's just me.

 

Remove the transmission pan covering the valve body and clean off the magnets, then put on a new gasket and fill the transmission back up.

The magnets and colour of your fluid are going to give you a good idea of the condition of the transmission.

The gasket will cost you $20 from Nissan, and you'll need roughly 4 1/2 - 5 qts to fill it back up. Easy to do, so if you can change your oil, you can do it yourself.

Personally I would never do a flush, heard too many bad reviews, but its up to you.

If it was bad why would dealership recommend it? I doubt they would want more headaches with there customers. I just had transmission flush done at 57k car is smooth.

 

Transmission flushes of any kind is not recommended for the g35. a drain and fill maybe once but thats it. don't do a complete flush.

 

Me either....^.... that almost as bad as PepBoys or Sears! Have your AT drain/fill at Nissan, they'll use the correct fuid and do the job right. There are some question about doing a "Flush" even Nissan can't make up their minds if it's a good thing or bad. Cost is near $300 because it requires twice the fluid to complete....Gary

 

Just had trans flush $110. I could see high mileage vehicles not getting a flush and since op has a high mileage g what I'm saying doesn't matter..lol personally I keep up on all fluids ahead of time. I don't complain about premium fuel or maintenance costs. It is what it is. Buy a hybrid or get a bike..lol

The dealer will sell you whatever they can at the highest price they can.

 

You really aren't supposed to do a flush on a high mileage (100K+) vehicle, unless it's something you've routinely done every 30K miles or so.

Flushing a trans can do some bad stuff. Basically you have 100K miles worth of worn friction material circulating in your trans. Flushing that all out can do more harm than good.

Drain/fill is the way to go. I just do it every 25K miles with an oil change. It takes less time to do and costs me 4 quarts of oil. Just jack up the front of car, drain the pan out, and refill via the dipstick. Done in 10 mins.

I'm at 116K miles and getting ready to do this a 5th time.

 

If it was good, why does the manual say not to do one? I would rather listen to a manual, put out by the manufacturer who built the car rather than listen to a individually owned company who's income comes from fixing the problems with my car.

Fixing, or not fixing

I brought my car in because the brakes were notoriously soft and required double pumping in order to stop at high speed. Car was under warranty, so i didn't really investigate much other than bleed the brakes and give them a visual. So i had the car in for the airbag recall and had them take a look at the brakes. They called back and said "brakes feel fine, nothing wrong"

Couple weekends after I decided i wanted to take a look. I pulled all 4 calipers off and looked them over. I discovered my rear driver's caliper seized badly only the inner pads pressing on the rotor. New caliper fixed the issue...$50 on my dime for a rebuild because I was too pissed off to bring the car back to the dealer.

Car stopped wonderfully after that


My lesson? The dealer isn't always right
