I got a foreign used toyota corolla 2003/2004 July last year, I only did normal engine service without any changes to the transmission. July this I discover that the ATF is a bit short so my mecho told me to buy Mobil 1litre ATF to top up after wich gear is still working fine but I want to ask gurus in the house at what interval does changing of ATF necesaary or based on my explanation above do I need to change/service the gear asap?

I will appreciate urgent response

I drive Corolla 2006,the gear won't engage until I throttle same to reverse .please I need ur advice

Please i need solution.
My lexus rx 350 2010 always show “transmission oil high temperature” if i drive in the high way in high speed within 30 to 50 minutes drive,i have replaced the radiator to double cell,changed the gear box oil with toyota WS severally,even attempted to add additional cooler yet nothing changed.
Apart from the warning on the dash board everything works 100% perfectly,at a point i decided to ignore it and wait for the day the gear box will go bad and i can replace it.
No check engine,the car have also been diagnosed and there is no fault code.

EngRichie:
This needs good diagnosis. Let me list few posible causes.

1. Over filled transmission
2. Under filled transmission
3. Intermitent transmission oil temperature sensor connection
4. Faulty torque converter lockup (this should produce a code though)
5. Depending on drive-train design, a fault in drive-train can cause stress to the transmission

Automatic gearbox issues have become a reoccuring decimal to any automatic car owner. Slow take off, sluggish acceleration, lack of kick down, loss of drive while in motion, lack of gear change, aggressive gear changes, high engine revs without power in drive just to name a few.

From my observation and the complaints made by some of our customers, these problems usually start from a gearbox oil change that was recommended by the mechanic who then uses the wrong type of ATF oil for the transmission.

Most car manufacturers develop their own ATF formular for their cars.

Honda recommends their own formular ATF-z1 for their gearboxes manufactured between 1998 to 2009 and upgraded to the ATF-Dw1 for gearboxes manufactured from 2010 upwards.

Toyota uses the Type 4 ATF for their cars manufactured between1996 to 2007 and the Toyota WS ATF for ones manufactured between 2007 to present.

Most other car manufactures have also upgraded the type of ATF for their modern cars.

Using the wrong grade of ATF would almost certainly result in a failing transmission. Low grade ATF may not be able to handle the high temperature operations operations of a gearbox. Under very high temperatures, low grade oil loses its fluidity and may begin to boil causing loss of hydraulic functions by frothing or foaming.

Some remedies I have seen used by local mechanics is to further add engine oil to the gearbox in order to thicken the viscosity of the ATF. This in turn puts the pump under great stress as the thicker oil would require more effort from the pump in distributing the oil under high pressure as well as the oil filter which is usually embedded within the transmission gear train. (The removal and changing of all Honda transmission oil filter would require the removal of the gear box from the car and stripping down the gearbox)

The resulting consequence would be an imminent and extreme overheating of the transmission and components such as the friction plates and a rapid degradation of the wet clutch fibres hence the loss of drive, slipping clutch and rough gear changes.

Replacing the gearbox or a total overhaul by an expert would be the likely solution but before then, an inexperienced mechanic would Send you on a wild goose chase by suggesting the removal and servicing or outright replacement of shift solenoids on the outer casing of the gearbox. These solutions Don't last as its just a temporal remedy to a terminal issue.

We constantly repair these gearboxes and those of other makes to a very high standard with 99.9% success rate and we recommend that if you are having serious issues with your automatic gearbox, ensure that the appropriate procedures are followed.

Thank you for your reply,
I have done necessary diagnosis and yet no error. Code.
The car does not have any check engine code.
The transmission does not have any issue at all.

I’m in Aba,Abia state,can you recommend anyone that handle this situation?

Good evening everyone
I bought 4K gear oil on my Highlander
Now when I drive it don’t not change gear At all

I was told to change the gear oil back to T4 and clean the gear box fitter

EngRichie:
My first suspension is transmission oil overfill.
Also, I don't know whether your car has separate transmission oil cooler or it is integrated with the radiator. If it is separate, check the coolant hoses or pipe that goes to the oil cooler to ensure that there is no restriction.

I shouldve seen this thread before changing my gear oil.

I found out my gear oil was leaking so I went to my mechanic who replaced the seal and filled it up with another oil.

The gear when put on D drive won't move but will move when on R reverse.

Now I've just towed the vehicle Sienna 2005 model to my house.

Any help here please?

Kashif, Gazzuzz, Makavele and other car gurus please I need your help.

MrPaul2:


Please I'm having this same problem with my Toyota Sienna 2005. How did you fix yours. I'm really down because I don't know what to do again

GAZZUZZ:


Replace the gear.

MrPaul2:

I had it's 250-300
