This guide is part of our common problems. For pricing, see the transmission repair cost guide.
The most common cause is low or worn fluid, which starves the transmission of the hydraulic pressure it needs. Worn internal components and solenoid faults are the other frequent culprits. Because fluid is cheapest to address, it is checked first.
The right fix depends entirely on the diagnosis, which is why a scan and road test come first.
Additives marketed as a slipping fix may briefly change how fluid behaves, but they do not repair worn parts. Relying on them can delay a diagnosis while heat and wear continue. Treat slipping as a prompt to inspect, not to pour in a bottle.
Sometimes. If the cause is fluid-related, a service may resolve it. If internal parts are worn, it needs a repair or rebuild. A diagnosis tells you which.
If low or degraded fluid is the cause, it can. If the slipping comes from worn internal components, a fluid change alone will not fix it.
It ranges from inexpensive (a fluid service) to significant (a rebuild), depending on the cause. Catching it early usually means the cheaper end.
