Rarely. Dealerships want you to do it often.

In the 60s and 70s the service cycle was every 60 to 70 thousand miles. This is what I do and it works out fine.

By far the most important thing you can do to save your transmission is to place a small magnet on the bottom of the transmission pan near the fluid plug. This traps small metal flakes and chips. You can also buy plugs which have magnetic collectors in them.

How to flush transmission in 2000 Kia Sportage?.

there are two methods
1-- drop the pan and refill with fresh oil ( 1/2 the oil still left in the torque converter)
2--- take it to an accredited specialist auto transmission shop and have the oil changed while running ---this flushes out the torque converter as well as the transmission
although this method is by far the best if there is water contamination in the transmission, it is considerably more expensive as it takes around 2 times the capacity of the transmission and you have to pay for that oil
best have a chat with an accredited specialist shop and get a good prospective of which way you want to go

When my 1998 plymouth grand voyager runs a long time the transmission starts to have a hard time shifting or not shifting at all until it cools down.

How many miles? I'm guessing 150k atleast. A complete transmission flush/pan filter is probably your only option. Other than that, it is mechanical and needs to be rebuilt or the torque converter replaced, etc. Basically, if the flush/pan filter doesn't work, you probably need a new vehicle.

How can I flush my 2002 axiom Isuzu transmission?

I don't recommend using the flush machine on any vehicle. In the case where you have to flush the transmission then you need a special machine that was running about $160 to $200 to flush a transmission. I recommend removing the drain pan and draining the transmission. After the transmission is drained start the vehicle for about a minute to empty the torque converter. Replace the filter and the pan and fill to the proper level. Test drive the vehicle about 2 blocks to make sure everything gets filled and top off transmission as needed.

Do I really need to do a transmission flush, I have 106,000 on my 06 Sienna and am not having any problems - thanks

you need to look in your owners manual to see what appropiate mileage it is for your transmission to be flushed out, 106,000 miles is definitely too long for this procedure, i normally flush mine out at 30 - 40,000 miles , then again around 65 - 70,000, and so after, i am suspecting, since you have never had this procedure done, they might want to replace the transmission filter, and pan gasket also, but waiting too long sometimes can cause transmission failure, because there has been times , when a transmission has went too long before being flushed, varnish had built up on the internal parts, and then when you flush it out, the new fliud can remove the varnish gradually, and allowing clearances between the parts, and transmission failure could happen. if you have any doubts about it, you can also contact your toyota dealership, thank you. hope that this information has helped.

(1996 Volvo 850)How do I do a transmission flush?

yes, you need a transmission flush machine. it is the only way to get 100% fluid exchange. i would strongly recommend having this professionally done, as a transmission is a very expensive experiment.

What type of transmission fluid can i use for a transmission flush. there are new imports multi transmission fluid avialble at half the price of factory oil? is that okay to us? and how many quarts do i...

The newer vehicles today use synthetic fluids in their engines as well as the transmissions. Any type of synthetic transmission fluid will work. You will need 12 qts. of fluid to flush the unit. But usually to flush a transmission you need a transmission flush machine or access to one. Unless you are going to drop the filter pan then you are really not flushing the transmission.

Transmission problems in the RX300 are common for those who never flush the transmission fluid. I would strongly urge you to quit driving your RX300 and get it to a dealership where they can flush the transmission fluid. There is no transmission fluid filter (per say) but there is a "screen" inside the transmission that needs to be flushed out (this serves as the filter). Pull out your dipstick for the transmission and smell the transmission fluid - does it smell burned? I hope not, but regardless, take it to a dealership and get the tranny flushed and see if that makes a difference. Also, continue to flush the transmission every 60,000 miles at most! Lexus says that you do not need to flush the transmission, but I think you do. I have a 2001 Lexus RX300 and I have had no problems with the tranny and I've flushed it at 60,000 miles and then again at 115,000 miles. I now have just a little over 120,000 on it. It's a good running vehicle but you need to care for it!

Flush engine - transmission

Engine & Transmission Flush

You might have been told, by your dealer or mechanic that your engine oil or transmission fluid are very dirty, & an engine or transmission flush, is recommended. The flush will clean the engine or transmission, & those will last longer. This is only part true a clean engine or transmission will last longer, but I'm not sure that flushing them is the best way to clean them.

What Is An Engine Or Transmission Flush?

Flushing is forcing high pressure of fluid against the normal flow of the fluid. In simple words if the normal flow is left to right, the flush would force the fluid right to left.

This is done by connecting a machine that will force special solvents back through the engine and transmission. The idea is that by forcing cleaning solvents backwards through the system, it will get all the junk and garbage that has formed over time and "flush" it out of the system. In theory this sounds very good, but in practice, it can be dangerous.

The Dangers of Flushing your Engine or Transmission

Flush machines force high pressure cleaning solvents back through the engine and transmission and clean out some of the accumulated junk that has formed, so far all is good. Now the problems start, engines have small passages and galleries through which oil or automatic transmission fluid flow and there are one-way valves that keep the fluids from backtracking for whatever reason.

By using an aggressive cleaning procedure like flushing, large chunks of accumulated sludge are broken off and forced backwards through these galleries and valves and, more often than not, lodge tightly and block them. This cuts off the normal flow of the fluid and causes lack of lubrication in an engine and abnormal or no shifting in a transmission. The results are expensive repairs, or more often, engine or transmission replacement.

That's my knowledge about the subject, hope it was helpful,
