According to infinitihelp.com, the automatic tranny fluid and engine coolant fluids are supposed to be replaced at 30k and 60k. has anyone does this, and how much does it cost at an infiniti dealership? is it really necessary? thanks.

 

Shoot if soo... I need to get that done myself..

 

yea ... i got both the things done recently coz i didn't know when the previous got them done ...

30k interval for Auto Tx and 60k for coolant 30k for Air Filter and 15k interval for fuel filter.

 

how much did the tranny fluid cost

 

$90 at Jiffy Lube ... I wish I had known abt Mobil lubes then and I'd have gladly paid any extra amount ... now i'll wait for another 20k

 

There is a how-to in the 4th or 5th gen froum. I did my own auto flush with mobil 1 ATF. I think I needed 10qts of ATF. It wasnt too hard, but I did make a mess by disconecting the wrong side of the return line. I was totally soaked in ATF... That stuff doesnt taste very good.

 

i would never let jiffy lube touch the i-ride

 

lol agreed... I made an appointment with my mechanic, only charging me $30. But he uses Castrol.

 

ill get it done next time i get the oil changed.

 

... my car DR orders anything or tells me where to get the good lube for cheap then i bring it to him along with breakfast/lunch and its a done deal... heh

 

i have no idea what you just said

 

well i got my auto fluid done last month the car shifts alot more smothly so it was def a worth it deal i payed 50 bucks to get it done.

 

did you get it done at the infiniti dealership or somewhere else

 

i had my personal guy do it for me he works for BMW so i figured he might as well.

 

If your car has never had its fluid replaced before exceeding 100k, you might want to rethink getting it done. The manual advises against doing it on high mileage cars, and I can vouch for what happens if you do.

I had the fluid replaced on my Maxima at 125K at a Nissan dealership, and it caused the tranny to slip all over the place. What saved the day for me and my Max was Lucas Tranmission additive - -this stuff is worth its weight in gold.

Not only did it fix the slippage, but the tranny went all the way to 300K before it finally needed to be rebuilt. I drained the tranny and refilled it with Nissanmatic Type C fluid and two bottles of Lucas.

Renewing (not replacing) the fluid by yourself is not that hard to do -- you can drain it like you would the oil pan. Of course, you will not get out all the fluid, but unless your fluid looks really yucky, I would not worry about it.

You can use the end of a 1/2" socket wrench (or a 1/2" adapter on a 3/8" socket wrench) to remove the plug.

Even if you decide to take your car in to have someone else do it, remember to add at least one bottle of Lucas to the fluid.

I would highly recommend adding Lucas even if your tranny does not need a fluid change. You will notice a difference right away in smoother shifting.

 

the car seems to shift pretty smoothly right now. the car only has 36600 miles on it. i am going to be driving it for a few more years, so i want it to run well. would replacing the tranny fluid soon be a good idea?

 

i did flush-n-fill at 103k ... it's fine ... no additives

 

I have read in many lubricant forums, including maxima.org that Lucas lubricants should be avoided at all costs(engine & tranny). Because they screw up the chemical composition of the oil.

Here's an article making tests with lucas added and it makes the oil foamy and at the end rusts components.

Here's the forum where I read that info, just look for it.

DO NOT USE LUCAS!!!

 

Thanks for the heads up..

 

is that the same lucas reagent i used in my organc chemistry II class?

 

Luigi38:

That article you quoted above involved this guy (Bob, The Oil Guy??) putting Lucas OIL ADDITIVE into a gearbox. What will he do next? Put gasoline additive in his crankcase?

I can only vouch for my experience with the TRANSMISSION ADDITIVE only. I had the opportunity to look at the guts of my tranny when it was rebuilt at 302,000, and there was no corrosion...or bubbles for that matter inside.

The gears and bands were worn down as you might expect them to be. Actually, first and second gears worked just fine, but third gear finally gave out one morning, and that is why I had to get it fixed.

I'll backtrack here a little by saying that you probably should not add Lucas to a working transmission that has no problems.

On the other hand, if you have a tranny that is slipping, your choices are limited to having the tranny rebuilt or replaced to the tune of $1,000-$1,800, or trying a bottle or two of Lucas transmission additive.

It's not going to make your transmission worse, by any means, and the odds are in favor of it helping it.

As for other brands of additives, you should be wary. There have been numerous complaints filed with the FTC about Slick50, Valvoline Engine Treatment, STP Engine Treatment, zMax oil additive, DuraLube, and Motor Up oil additive.

Now, here's a little test for all of you doubters to do:

Go to Google and do a search on complaint "lucas transmission additive"

What you will find is ONE reference taken from the Acura TL forum where two members reported excellent results from using it.

I rest my case.
