Hi guys,

i am about to under take an auto trans flush on my KF verada this weekend.

i just want to make sure i have got the steps in doing this correct.


1, get 10L of mitsi auto fluid and a new filter.

2, warm the car and gearbox up

3, remove the right hand trans cooler hose from the bottom of the radiator

4, add a extra length of hosing to the trans cooler line so you can put the old fluid easily in to a bucket.

5, remove the trans dipstick and insert a funnel

6, get someone to start the car in neutral and start filling the funnel

7, keep filling the funnel while draining the old fluid into the bucket, once the fluid is the same colour going in as going out, stop the car.

8, reconnect the lower trans cooler to the radiator and install new filter.

9, start the car, fill the trans to its cold level, then put your foot on the brake and manually shift through the gears to spread the new oil around.

10, recheck the oil level, top up if nessercery.

11, drive around for 5 mins, then check the fluid level to the hot marker.



does this sound right guys?

or just drain the oil from the bung under the car.
when oil stops flowing start the motor and run for 10 sec.
repeat this untill no oil comes out

fit bung back in refill with oil untill correct level. go for a good 10 min drive repeat the process again.

same results as removing the hose

Its better not to let the gearbox work without any oil. Its a nice way of causing damage. Yes it can be done like you said - however, I wouldnt recommend it.

His way is much more thorough, including having the oil clean out any old oil deposits/build up.

Are you sure you are doing it correct? or writing a tutorial LOL. This is textbook if i remember correctly, hence why i am going to copy what you do lol.

Shibbs

i just want to collect the correct procedure is a easy to find thread, i did a search on here but found scattered info.

im pretty sure i have it right, though i might add an additional step inbetween 4-5

where i drain the gearbox and retop it up with fresh oil so as not to push more old oil through the pressure lines etc.

Is this the same as a TJII? How much is 10L of trans fluid from mits?

i dont even know what a TJII is, 10L and a new filter was $87

Following is transcript from Magna/Verada workshop manual about replacing ATF.

1. Remove the right hand hose connecting the transmission fluid cooler pipe to the fluid cooler built into the bottom of the radiator

2. Connect a suitable length of hose from the radiator cooler pipe to the bucket

3. Start the engine and discharge the ATF , Neutral gear and idling

CAUTION: Start the engine and then stop it within one minute. If the ATF is discharged before the one minute elapses, stop the engine at that time.
Amount of ATF discharged: approximately 4.5 litres

4. Remove the drain plug at the bottom of the transmission case and discharge the ATF.
Amount of ATF discharged: approximately 1.0 litre

5. Change the external fluid filter.

6. Install the drain plug fitted with new gasket and tighten the plug with 32 Nm of torque.

7. Fill with new ATF through the dipstick tube.
Amount of ATF added: approximately 5.5 litres

NOTE: Stop pouring if the entire amount of new ATF cannot be added (do not exceed "Cold" level)

8. Repeat the procedure in step (3) and discharge approximately 3.0 litres of ATF.

NOTE: Check the ATF discharged in step (8) for contamination. If it is contaminated, repeat steps (7) and (8)

9. Add the new ATF through the dipstick tube.
Amount of ATF added: approximately 3.0 litres

10. Attach and secure the hose that was disconnected in step (1) and insert dipstick

11. Start the engine and let it idle for one or two minutes

12. Move the selector lever through all gear positions, ending in Neutral position

13. Make sure the ATF reaches the "Cold" mark on the dipstick. If there is not enough ATF, add more

14. Drive the car until the ATF reaches normal 70-80 degrees Celsius and recheck the ATF level. The ATF level must be within the "Hot" range.

NOTE: The "Cold" level is for reference only and the "Hot" level serves as the standard.


It is very handy if there is someone to help you with starting and stooping the engine, or to hold/fetch something for you. Your hands will be dirty (and clothes as well if not careful). Wear disposable gloves and have some rugs and cardboard around. Buy 1-2 buckets from Bunnings and some duct tape. You don't need duct tape for this but one can never have enough duct tape lol
To reach normal operating temperature, drive the car for minimum of 16 Km.
Quantity of ATF in transmission is 8.5 litres.

you are the legend, thats exactly what i was looking for :)

i wasnt really tooo far off on my guesstimates, but that helps tremendously :D

No worries, when doing step 8. you will easily see when old fluid is drained and new fluid starts to emerge. At that point stop the engine . It helps to have transparent hose. Collect old fluid into a bucket, you should end up with about 9.0 litres.
Take your old fluid to the Tip. They have collection point for it and it is free of charge.
Be very meticulous (I think that is the word) when filling new ATF not to overfill or not to have enough fluid in the transmission. In either case fluid may get air into it which will cause pressure to be erratic and that will affect operation of the transmission. Read more here.....


To check fluid level transmission should be at operating temperature 70-80 degrees Celsius. Drive the vehicle for a minimum of 16 kilometers to bring the transmission to operating temp.
Place the vehicle on a level floor and apply handbrake.
With the engine idling, move the selector lever through all the gear positions, momentarily stopping at each position. This will fill torque converter and hydraulic circuit with fluid, then place lever in "N" position.
Allow the engine to idle in NEUTRAL during the checking procedure.
The fluid level should be in the "HOT" range.
If fluid level is low, add ATF until level reaches "HOT" range.

NOTE
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with fluid. Air trapped in the hydraulic circuit forms bubbles which make the fluid spongy, therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. When the transmission has too much fluid, gears churn up foam and cause the same conditions which occur with low fluid level, resulting in accelerated deterioration of ATF.
In either case, air bubbles can cause overheating, fluid oxidation, which can interfere with normal valve, clutch and servo operation.

the only thing running in park is the oil pump.. running a auto for a short time with out oil will not do any damage.

it no different to starting the motor of your car just after a oil change.. there is still oil in the auto after flushing the oil out.

its just another way to do it. no different to removing the hose and running oil into a bucket.. if your that worried take it to a workshop that has a auto flushing machine. pay the $180 and be done with it.

to4garret are you able to collate ur nfo and pop it into a DIY article in magna mods as per

Cheers

will do a write up after i've finished.

will say one thing...


:P

righto, done...

note: no matter how hard you try, you can not avoid dropping lots of fluid everywhere if your not using a hoist :(

and that bloody (not a swear word) trans filter! its a PITA to get off, i suggest using the correct tools for the job and not to attempt the bodgy filter romval via hammer and screw driver lol

i think my verada must not have had a flush in many moons, because the stuff that was coming out was BLACK AS!

i had a little trouble getting the fluid level correct because the new stuff was so clean :D

but now, she is a TOTALLY different car, shifts are very very smooth, has removed a few shudders and in general is so much nicer to drive!

highly recommended to do, and if you do it yourself you save over $150 in labour charges :D

You deserve A+ for effort. Doing it on a floor is not easy. Luckily my driveway is on a slope and that gives me an extra 250-300 mm. I can see you are able and willing to work around a car so I suggest you invest some $ into basic tools which you can use on any car anyway.
Torque wrench, trolley jack and 4 car stands will make your work much easier.
When some of the car shops around your place have a sale it is good time to shop for it.
I calculated that by servicing the car myself I save about 46%. That allows me to treat my car with the best fluids/oil/parts I can afford. By servicing 3 cars my family owns and 2 cars my brother has we actually save quite a some amount.
Another thing I don't like when using service or mechanic is that they use air tools for about everything. That would not be a problem if they adjust the torque as required for certain bolt/nut. I think it is pathetic when well known tyre chain use torque wrench to tighten wheel nuts after they over tighten them with air ratchet.

I am surprised that you had trouble with the filter, but yea, if you don't have the right oil filter wrench it can be awkward to remove it.

if you went to a workshop that used only hand tools and torque wrench to tightened every bolt you would pay a heap more in labor time.. most people would rather pay less to fix there cars as they are a money pit and not a good asset.

air tools are fine as long as you check the bolts when finished. i can get the plenum off a magna in under 2 min with air tools. takes about 10 with out.

i can also get the plenum off a vr commodore in 12 min using air tools. a job that takes 30 min without the air tools.

I don't have a problem with workshops using air tools. Problem is that the person who use it can't be bothered to adjust torque for specific application. Result is that bolts/nuts are over tightened. Best example are wheel nuts.

Bit of a silly question but where is the trans filter on a KH Verada?

I assume that TH Altera and KH Verada have the same engine and transmission, so the filter is located on top of the transmission, next to dipstick , underneath the air intake snorkel.

Yeah you'd think that but it doesn't.

If it is not below your intake snorkle, then you do not have one.

Later models dont have an external filter.

Ok thanks for that.
