Auto Transmission Oil Question

[mello555]

Hi,

i recently changed my Nissan March K12 automatic gear oil using the flush method using an ATF exchange machine at laughfs car care centre. But they didn't remove the pan and clean any filter.

I want to know whether K12 got a transmission oil filter? Is it compulsory to clean.? Also I haven't seen any instruction to clean any transmission oil filter in service manual.

[mello555]

are there anyone to help?

Hi mello555,

There is no need to remove the oil pan unless there is any issue. There is a Auto gear Sump nut. By removing it they can drain the ATF.

Was it a flush ? or a oil change? There is no as such flush method.

I have n't heard of a ATF Filter so far.

In a flush they clean the Auto gear System by adding constantly oil and draining it out untill it cleans your whole system. this needs to be done (simply) only if your exiting oil is at a very bad condition and can not be mixed with new one or in an Oil type change. Now in my case I had to flush because I Changed form Dexron III to T4 oil.

hi car madness , thanks for the reply. actually I did the flush method through exchange machine at laughfs car care. But still some people generally suggest to do a manual change by removing the pan and to clean the filter which might contain contaminants / dirt which I didn't do.

I want to know whether there is a transmission filter.

but flush method removes almost all of old oil whereas manual will leave abt 1.5 ltrs of old oil.

I used havoline atf-j which is compatible with nissan matic-j recommended for March K12.

Yes that is why I said that only if the oil is at very bad condition or changing the oil type you need a Flush.

Let me explain what is flush means,

During the fusing they use ATF (new) to clean out the gear box. Then they use about additional can of ATF during the flushing. While they add ATF form the other side they drain it off the sump nut while the engine is running on the vehical

This is repetdly done untill the system is fully cleaned. The flush is much much more expensive than an oil change.

And yes it is always preffred to use the manual drain so that all the dirt will go away under the gravity.

Have you ever heard of Radiator Flushing ? itss similar to that

I think the fluid exchange has been performed correctly. Under normal circumstances there is nothing else to do as long as your automatic transmission is performing correctly.

A flush is normally done when an ATF extractor is not used to get most of the existing fluid out of the system, or after a clean up of the valves etc to get rid of any left over sludge. This is not really required when an extractor is used if all you are trying to do is change ATF oil as part of a normal service.

Do i have to clean the transmission oil filter for a complete clean up of the system.? Some say that when you remove the pan there is a filter there to remove the contaminants. pls advise.

This is not normally required and if I'm not mistaken not all cars have such a filter which can be cleaned in that way. They only remove the pan when they do a manual ATF change to get as much fluid out of the system as possible and to supposedly give the sump a clean. Personally I'm not 100% convinced of the value.

I got the Forester's ATF changed today while I was passing AutoMiraj in Ratamalana. Wanted to DIY this weekend, but something came up. As usual they wanted to 'flush' the system and all that BS. I said, no, here is the filter, just drain the MFr and pour in 4 liters of ATF and be done with it. 15 min job. If I did it at home I would have made a big mess as the when you remove the filter oil spews everywhere. This has the screw on ATF filter, which makes life that much easier.

Which brings me to the question, how much is a liter of ATF Dextron 3 these days? They said its 1100 a litre and I did not ask around as with the ZF in the old BMW I had I was used to paying close to 7K a liter, and this is a bargain...

I did ATF change about 1 1/2 moth ago for my previous vehicle (Teriose) form agent The Dextron III was about Rs 3200 4L can. But They suggested to use T4 saying its a low viscosity than Dextron III and so and so. The price of T4 was Rs 4800 4L can.

caltex texamatic is 2950 and BP Autran as posted by Don earlier is 3200. Mobil 1 litre is 1100 which i think is very expensive

Thush its possible that the ATF fluid was changed with the incorrect grade of fluid. This is very possible as most shops seem to have no clue which fluid to use for which. If you mention your car model, and if you have the empty canister the grade of ATF fluid used, fellow members maybe able to advice you if it was the correct grade or not.

What is the grade on the Havoline ATF? Also is your car standard auto, CVT or hyper CVT?

[thush123]

Dear Friend,

Earlier also i change same gear oil caltex MSDS - Texamatic 1888 but that time no problem.now after engine repair it happen

​the mechanic told me to change by machine then it will be ok

the car is not speed on mountains

[kush]

K11 came with both CVT and conventional Auto boxes, hope yours is not CVT.

Texamatic is wrong oil for CVT

[hatharasinghe]

As i posted on 2nd Aug , after doing manual oil changing ( Pls ref previous post) there is a remarkable improvement pickups and all so first find the suitable oil by checking the car manual or can find Net then do manual as once remove the bottom and do necessary cleaning then its good.

Hi CAR_MADNESS,

I have a Paj IO and recently did a ATF change due to invalid or unacceptable shifting(http://forum.autolan...ion#entry215385).

They did a manual change and used a dextron III ATF, but they did not do any filter cleaning. Will it be a problem?

For a flush and change, what would be the cost? I saw an ADD in hit adds that said the flushing machine charge is 650/- at Nalaka Wheel Allignment.

Also any idea if valvoline dextron III is available in SL?

Thanks

Can somebody explain on this issue..?

Can i use dextron 3 instead of dextron 2? Because it has better properties .

As far as I know.. You can use DX-III in a DX-II tranny but it's not good or recommended to do the other way around...
