Three-quarters of all transmission filters today are not a simple screen, they are made of felt. I've never done a power flush before, i've always just dropped the pan and replaced fluid and filter. Don't over torque the bolts or you could crack the pan or strip a bolt. Probably close to max weight for a sixteen foot tandem with brakes. What is a power flush? Clean the pan and magnet thoroughly, and replace the pan gasket. Dispose of old fluid and filters properly to protect the environment. But I may be wrong.
Be careful because there will be some fluid in there. Late model transmissions are very contamination sensitive due to their complex circuits and electronics. Clogged filters restrict fluid flow, which lowers pressure to clutches and bands. I just did a flush. If you don't wish to, then skip over those steps They'll be in yellow.
This bracket is on the driver's side of the transmission, just above the transmission pan. Then rebolt the pan to the tranny make sure you don't strip any of the bolts. The problems that can stem from a power flush is that the fluid is pumped backward through the hydraulic systems and valves. Then, supporting the pan with one hand, use the other to completely remove the last bolt. The capacity of the trans is 23 or 24 quarts. Fill the filter withnew fluid. Then drop the car down a little bit add you fluid through the dipstick opening.
Once these are removed, you and a couple helpers can lift and slide the box back about 18 inces to get access to the top of the fuel tank. This is an easier way than lifting the truck and dropping the tank. And the problem is compounded even more if the pan isn't dropped and the filter changed afterwards. Add 3-4 quarts of new fluid in the trans dipstick tube to the full line on the dipstick and repeat. Answer drop the pan, replace filter, clean pan replace gasket torq bolts to spec. Next, you'll need a small hose clamp, flare nut wrench and something to catch the fluid in.
I went synthetic on the new fluid along with transfer case and diff. One of the mechanics was telling me that if we switch it over to Amsoil or anything else for that matter that it will void the warranty. Add new fluid to spec volume. Clean the pan of the transmission completely including the magnet. Make sure the car is cold, dont try it when its hot, you will need a socket wrench also. The video above shows where the transmission fluid dipstick is located in your Sierra 1500 and how to check the transmission fluid level.
It will work loose with a downward pulling motion coupled with a little bit of twisting. I understand draining the 6 qts or so by dropping the pan leaves some old fluid in there. Some have done it without removing it, but I couldn't tell you how. I used a suction device down the dipstick tube to suck out most of the fluid and then dropped the pan. It will rest on the exhaust Y-pipe.
I've not done one personally that new of a truck either, the dealership did my wife's 08 Tahoe last time 40,000 miles and they did replace the filter. At this point, I'll go over how to change the filter. Any repairs that occurred outside the standard warranty period will not be honored. Got any input or information on that???? This is a major misconception. At the time of a fluid evacuation service, there is no way to know the condition of the filter and how clogged it may be.
Let's turn our attention to the pan. I do my Suburban with a 4L60E transmission every 12,000 miles I still own the machine , and I bought it with almost 90,000 on the odo. I do need to get a drain hose though. Fill the transmission with new fluid. I've never had one problem. Be very careful to use your vehicle jack correctly while performing this work.
Pull straight down on the filter. I did see where PepBoys had it as well. Felt holds dirt particles within tiny pores in the felt. If it ain't true, don't say it. Really, I'm just a cheap bastard and I don't want to spend the money yet.
