Does a trany fluid change have any magical cure for a transmission thats not working correctly?Is fluid a cure for any transmission problems?
Changing the fluid cannot correct a mechanical or electrical problem. There are some symptoms that might go away with a fluid change, but if there is a real problem inside the transmission, a fluid change won’t fix it.
Fluid is a cure for a fluid problem. Sometimes the fluid is bad or the wrong type and needs to be changed. Other times it is something wrong with the hardware or computer and fluid can't fix that.
Think of it as preventive maintenance, like a regular oil change. It’s not going to fix anything but will help prevent bad things happening as opposed to if you don’t do it.
