Car transmissions are usually very complicated and more sensitive to misuse or mismanagement .
I have used one Honda CR-V for some years now and decided to drain and change the transmission fluid.
I honestly cannot recall ever changing the transmission fluid of any car I have ever used because most times before they would be due I would have sold and changed the cars.
But with the economic situation now, we now manage what we have so no change of cars for now.
Thus I had to change the transmission fluid of my 2008 Honda CR-V which has lasted a bit.
I told my mechanic to buy the fluid then I would pay him after the job, a system we usually go with.
He bought the number of cans of the fluid according to his prescription and while pouring in the new fluid, I halted them before they poured the last can.
I told them I would take it home and check the level in the morning then if need be I will top it off personally.
Lo and behold, when I got home I decided to run a QR Code scan first on that remaining can, sadly it turned out that it was probably a code lifted off a phone that was pasted on the can.
I had taken one of the empty cans home and also ran the same QR Code scan on it and this passed.
I went back to the mechanic’s workshop with apprehension praying we had not poured some fake transmission fluid into my transmission.
Getting there, i gathered the bottles from the ones poured into my car the previous day and checked them all, luckily, it was that last can that was the fake one.
Funnily, it was not the exact spec for my car but it (if original) can be used for my car.
Going forward, I pray I will always remember to check every checkable item that goes into my car. This is not a period for unnecessary expensive automotive misadventures and I also advise you to do the same.
