A transmission fluid change will help to restore your system to good working order and is the cheaper option. It is also a relatively simple task that can be undertaken by vehicle owners. A transmission fluid flush is more costly, but will replace all of the fluid and any contaminants that have built up in the system.
Why You Should Never flush your transmission fluid?
Transmission fluid is highly detergent which can wash the varnish off clutches, causing it to slip. Pressure flushing can cause aging seals to start leaking. When it leaks more than a quart it could burn up the unit.
Is it worth getting transmission flushed?
Many manufacturers recommend a transmission flush every 30,000 miles or 2 years. However, not all recommend this frequently – some suggest a flush only every 100,000 miles, and others don’t recommend a transmission flush at all. … A transmission flush can extend the life of your transmission.
Is changing transmission fluid a bad idea?
The smaller particles will continue to circulate and cause additional wear to the transmission and degrade the fluid. Changing the fluid and filter is never a bad idea, as long as you use the correct parts, as there are many types of trans fluid – all with different characteristics.
Is it bad to change transmission fluid on high mileage?
Changing the transmission fluid on a high-mileage car is risky. Don’t do it unless your transmission is running fine and the fluid is first-rate, because it can make transmission failure imminent.
What’s the average cost of a transmission flush?
A typical transmission flush will cost around $150. A transmission flush on smaller cars may cost in the low $100s while it may cost more than $200 on larger vehicles. A good rule of thumb is that a flush costs about twice as much as a fluid change.
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).
