Why you should never change transmission fluid?
If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.
Why does my transmission slip after fluid change?
When the old fluid is replaced with new all that suspended friction material is now removed also. It is likely the trans is worn pretty good and with the last crutch of the friction material in the fluid now gone the trans starts the rapid spiral of slipping (no pun intended).
How long should I let my car run before checking the transmission fluid?

Can low transmission fluid cause a check engine light?
Low Transmission Fluid Your transmission fluid plays an important role in keeping the parts of the system lubricated. If the parts of the transmission are not properly lubricated, extreme friction can occur, which could result in damage. As a result, the check engine light can be triggered.
