Back to page index Filter and pan gasket: The filter should be changed with the transmission oil pump fluid, just like motor oil filters. As the old fluid transmission oil pump side of the diaphragm fills it pushes the diaphragm up and forces new fresh fluid into the transmission. So you can see that all the fluid leaving the pump does not go to the cooler. Here is transmission oil pump what I do not like about this type of machine.
When the filter is replaced it has to be done with care. Those poor people are suffering from invincible ignorance and refuse to understand the benefit of transmission oil pump a proper transmission flush. It is common for at least one of these gaskets to slip out of position during installation and cause air to leak into the pump pick up causing it to break suction and loose output pressure. I will tell you transmission oil pump that this type a flush does take more effort and makes more of a mess, costs a little more, but I think it is worth it. It is made by Permatex called Right Stuff and comes in a cheese whiz can. The industry standard it two years OR 24,000 miles which ever comes first. I got an e-mail from a guy that said he was told by a Toyota Service Rep that there is no filter in the transmission. There are some transmissions out there that do not have replaceable filters, transmission oil pump but this is not one of them. The engine is started which turns the torque converter and the input shaft on the transmission. This causes fluid to transmission oil pump flow through the cooler line. When you drain the pan through the drain plug you will only drain about 3 of the 15 total quarts. In just a faction of a second you just bought a new transmission if the filter clogs. Now if you were counting that is a total of 15 quarts of fluid. The transmission on the 4Runner Tacoma is not made by Toyota. Just make transmission oil pump sure they are all properly positioned during replacement. If transmission oil pump it is dark, burnt smelling, and you see little flakes or speck in it, DO NOT FLUSH IT. When I got home I put another 3 transmission oil pump quarts in to bring up to the full mark. There seems to be as much bad info out there about transmission flushes as there is about synthetic motor oil. Really transmission oil pump pretty simple. The other thing I do not like about this type of flush is that they sell the supposed benefit that they do not have to drop the pan and change the transmission oil pump filter like that is a benefit. I transmission oil pump use something that I think is a little better. This type of flush machine does not remove all the old fluid, but it continuously dilutes it down with new fluid. This machine only supplies fresh new fluid to the pump intake and as the fluid passes through the transmission it dumps out to a collection tray and never goes back through for a transmission oil pump second pass. They use the transmissions own pump to move in the new fluid that displaces the old fluid and the old fluid is collected and thrown away. After a while the old fluid is collected in the machine and it is replaced by new fluid. The top part of the chamber above the diaphragm is filed with new fluid. I have learned a lot about the transmission on my 96 4Runner and would like to share what I transmission oil pump know and I hope it cuts down on some of the confusion. They have two transmission oil pump kinds, black and red.
It transmission oil pump is available from most parts stores. There is only one way to get all transmission oil pump the fluid out of the transmission so you can replace it with new fluid. Unlike the engine oil pump and filter the filter is on the intake side of the pump.
A bunch of it is cycled through the transmission and dumped back to the pan without going through the cooler. As usual most of the people that are confused and causing the confusion are Toyota Certified Technicians and service reps. When it was reinstalled in my truck with its new performance torque converter, Level 10 put in 12 quarts for fluid. Do not wait for a color or smell change. It can go into the pan, and then sucked up into the filter that may clog the filter causing the pump to starve for fluid and a pressure loss. I will let you guess what I use. In these cases for reasons no one has figured out yet, if you flush a transmission in this condition it will fail transmission oil pump right away. What you are taking out should look like transmission oil pump what you are putting in. Premium synthetic ATFs will protect better and last 3-5 times longer then conventional ATF. This is fantastic stuff and does not require any drying time before you refill the transmission. Back to page index Cooler line flush machine: The first type transmission oil pump of flush machine connects into the transmission cooler lines. The black is for the engine and water pump and the red is for the transmission. On the engine the filter is after the pump and if the filter gets clogged there is a bypass valve that opens and oil bypass transmission oil pump the clogged filter so the engine is still supplied with oil. This kind attaches to the pump intake after the pan and filter transmission oil pump is removed. Back to page index Fluid: Now the last big question that remains is what type of fluid to put back in, conventional or synthetic. Premium synthetic fluid will lubricate the transmission better, provide better traction to the clutches, removes transmission oil pump heat better, and not break down as fast under high temperatures. There are three ports on the transmission oil pump filter where the fluid passes into the transmission. The goal here is to flush the trans BEFORE the fluid gets rancid. They do not use pressure at all. Some vehicles like Mercedes have a drain plug on the torque converter so it can be drained, but not on our Toyotas. The fluid and transmission is TOAST, but the transmission just has not figured out it should die yet. Real strange, but that is what seems to happen. Now the transmission has been flushed. The other is supplies the torque converter and the transmission cooler. All of the old fluid and crud is GONE and replace with fresh new fluid. That is to flush it. When the fluid leaves the transmission pump it passes to two different pressure regulators. It is similar to RTV. One regulator supplies fluid at one pressure to the transmission itself transmission oil pump that operates the pistons and controls gear shifting. For lots of different reasons that is an easy answer, synthetic. Most of the fluid is inside the torque converter, transmission cooler and the cooler lines. The line going from the transmission to the transmission cooler is disconnected and connected to the machine line in. He said that is was the very best ATF in the world. As you can see the machine cause no pressure and all fluid transfer is done by the transmission s own pump. That is not much of a fluid change at all. Everyone should have this type of service done every 30,000 miles, but definitely before your truck goes out of warranty. BG makes this kind and here is how it works. Looking in the pan is a fantastic diagnostic tool that can tell you if something is going wrong in your transmission. Then when you transmission oil pump go to pull off the engine revs and then the transmission engages very harshly with a tire chirp. The pan does not use a gasket, but many shops will try to install a cork one. The line out from the machine carrying new fluid is connected to the line going to the cooler. There is no way of telling when it will fail. If you decide to change the fluid like you should, you cannot get all the fluid out by draining the pan. Toyota uses their own seal packing material that is available transmission oil pump from the parts counter. The problem usually presents after hard stops and the transmission will not complete its shift into first. Home 4Runner Email Automatic Transmission Flushing Index: Cooler Line Flush Machine Pump Inlet Flush Machine Filter and Pan Gasket When Not to Flush Introduction: There are several subjects that tend to be a never-ending source transmission oil pump of confusion. There is transmission oil pump a chamber on the machine that has a diaphragm in it. Be careful when reinstalling the pan bolts, as they are easy to strip. It is a nice, high quality unit that is used by several vehicle manufacturers including Jeep. It never really removes all of the old fluid, but is far superior to just drain and fill. If it gets clogged, that is it, it is clogged and stuff does not get lubricated and the clutches do not get enough clamping pressure and they slip and burn up. It might be today, next week, or next year, but it is doomed. Now lets say some crud is flushed out of the trans with this flush method. The input shaft turns the transmission pump and it makes hydraulic pressure. I have seen the inside of my transmission while it was torn down at Level 10 having its upgrades installed. Each has its own gasket. Back to page index Pump inlet flush machine: Now lets talk about the type of flush machine I like.
Back to page index When not to flush: Before draining or flushing you should pull the dip stick and look at the fluid. The number of professional mechanics that claim that a flush will blow out the seals and cause damage to the transmission dumbfounds me. There are two basic types of flush machines and here is how they transmission oil pump work and the differences in the two. One that constantly comes up is changing or flushing the transmission fluid in the Toyota truck transmission. This process takes a total of 20 quarts of fluid to flush out 15 quarts of old fluid, replaces the fluid, and gives the mechanic the opportunity to look in the pan for transmission oil pump anything unusual that would indicate a pending failure. If your trans is in this condition just drive it while you save for a replacement transmission.
Dropping the transmission oil pump pan is very important.
Here is the BIG secret about transmission flush machines. My 4Runner Owner’s Manual calls for transmission fluid change at 30,000 transmission oil pump mile intervals. By looking in the pan you may get an indication that you are about to have transmission oil pump transmission trouble that might show up right after you get out of warranty. The amazement continues. It is your transmission oil pump truck, you decide what is best for you. After the service a new filter is installed, the pan replaced and then it is topped off with new fluid to the proper level on the dipstick. Where does transmission oil pump it go? When my transmission with being reinstalled in my truck at Level 10, I asked Pat the owner what transmission oil pump he thought about AMSOIL ATF. As fluid transmission oil pump leaves the cooler line it enters the chamber on the flush machine.
