Transmission flush or regular transmission oil change & filter?

I have a high milage car with a transmission that is slipping in between gears a little. Performance wise- Can someone please tell me the end difference between a power flush without a new screen/filter and a regular transmission oil change where they do put in a new screen? They both cost about the same ($130) So which one would be better for a 1997 Jeep Grand Cherokee with 170,000 miles and a 5.2 liter V-8. Thanks.Transmission flush or regular transmission oil change %26amp; filter?
save your money. if the trans is starting to slip a flush or fluid change WILL NOT help it. the trans is just plain tired. it needs an overhaul or replacedTransmission flush or regular transmission oil change %26amp; filter?
There are many great deals on many different types of makes and models. There is a huge Hyundai DUH sale going on, I'm glad I bought my new DUH suv. Its way cool, saved lots of $. Had I not done it, I would still be throwing good money after bad. My advice to you is: Do what you feel is right for you? Best of luck to you! :)
A power flush like you were saying is where all the fluid is sucked out of it. But where the gasket and filter are not touched. Then new fluid is put in. The other one is where the fluid is drained but a certain amount stay es in and you then you replace you gasket, filter and put new fluid in.





With that many miles on it i am not sure if you have been changing on a regular basis. I would go for the regular this time. Because most tyranny pans have magnets in them and the reason why they are there for is a real good indications to see if your tyranny is in good condition or not. The more wear and tear on the tyranny. You will see some slivers/shavings on the magnets. The less you see supposedly your tyranny is in good condition.
There are two schools of thought on this;


#1. A complete system flush purges the entire transmission of fluid including the torque converter. Ocassionally junk comes loose and may lodge in the small orifices and oil galleries and does not get out of the transmission.


#2. A new screen and filter is just that. The trans pan is dropped the oil drains out minus the oil in the torque converter. A new filter goes back in.


Neither of these maintenance steps will correct a slipping transmission.


I''m pretty much of the old school. With older cars We change the filter and fluid without disturbing junk. A newer car 50,000 and under a flush may keep smaller particles of junk out.


It's pretty much your choice.
In the flush, most of the old fluid is removed with a vacuum and then replaced. The transmission is not opened, so the filter can't be accessed. In the fluid change scenario, the bottom pan of the tranny is removed, the old fluid drained and a new filter installed. This is the option you want. The old filter, no matter how the shop words it, may still be clogged with debris from the transmission and it needs to be replaced. The fluid change may or may not solve the slippage. You may need new clutch packs and valves to accomplish that and in that case, the transmission must be opened, the fluid drained, and the filtet replaced.
