    Re: Transmission Fluid Change

    The job mentioned is done after a 200 mile Sea Foam flush!

    60K miles after the only known pan drop change since new the ATF was very dark but did not smell strong. We followed the write-up for the most part and it worked out well. We added a hose claim to the 3/4" ID (1" OD) clear tubing due to my physical limitations so we did not have to hold it on. We pumped into a clean 5 gallon bucket and put it into one gallon jugs.

    I put in a 16 oz. can of regular Sea Foam (did not have the same stuff except for the red dye with me on Thursday) and drove it for 200 miles over three days. 10 trips of 20 miles should much more effective than one 200 mile trip. Before pumping out the old I did see a piece of trash come out on the dip stick that looked like some internal build up that was floating on top the way it came out on the stick.

    Since pushing 16 quarts of new ATF through the system we have driven it 60 miles on some local trips. The shifting it hard to notice in a normal take-off but did several WOT red line take offs in Tow Mode to build as much pressure as possible on the slip connection at the radiator. The 5.3 will keep your back against the seat for sure in WOT take offs but we are running 93 Shell grain free fuel.

    I did remember to blow out the return line before the first pump down. That took some effort by mouth indicating there was several ounces in the return line.

    Tuesday we have to make a sales call in Nashville so that will be a fast 300 mile trip and I really wanted new ATF before that trip which will be the only trip before I turn the SUV over to the wife on her birthday. The new Cooper Discoverer CTS tires are awesome in all ways and Monday I take it in for a front end alignment.

    Now I did not drop the plan the pan at this time since that is called for every 100K if no towing, etc is involved. Basically I wanted the old oil out and the Sea Foam flush had made it even more dirty and I have the trip coming up.

    We went with Dexron VI which was $3.77 a quart but we did start with push of four quarts of DEX III/MER at $9.95 per gallon ($2.67 per quart). I am not sure if there is much gain from Dexron VI in our case but I wanted the best. I have purchased the $9.95 per gallon to do the 2002 Blazer/2000 Towncar bucket flushes in part because WM only stocks small amounts of Dexron VI but have the Dex/Mer in gallons which makes returning the old easier.

    I got the hose and a clamp at Lowes last night and 13 quarts of Tech Dexron IV fluid at WM for $3.77 a quart. The dealer said before it was machine flushed they would change the oil in the pan and add conditioners. I have added a pint of Sea Foam while it is not a 'conditioner' it does help clean up the varnish build up created by the fluid over time.

    This write up helped because I did not know how to make the connection. I have done this bucket flush with the motorhome but it has an add on cooler so making the connection was simple because the hose just clamped on.

    Re: Transmission Fluid Change

    As an update I am noticing my transmission now requires more braking to hold it back at stop lights since running the can of Sea Foam in the transmission for 200 miles over 3 days then doing the total bucket flush per the above write-up. Also stopping on a steep grade if it tries to roll backwards the transmission seems to go into a "hold" mode all on its own. The idle speed still is about 650 RPM because that was my first thought.

    Any thoughts on why the transmission wants to pull harder at the same idle speed with all temps at normal operating range?

    Re: Transmission Fluid Change

    I used Patrick's bucket flush write up to do the Blazer this evening and other than finding the connection VERY hard to seperate it worked as describled.

    As with the Escalade I added a pint of Sea Foam to the transmission a few days before but I only drove the Blazer 120 miles instead of 200 that I did on the Escalade. When we poured the 5 gallon bucket into the gallon containers there were some fine solids in the very bottom of the bucket that we pumped into.

    The output had less pressure when pumping down the Blazer than the Escalade. I am not sure why unless the Blazer has some ATF cooler restriction. It was a forceful stream but not like the Escalade. The transmission before this Jasper was eaten alive and I have wondered if maybe it loaded the cooler with junk that did not get flushed well by the shop.

    Re: Transmission Fluid Change

    I finally got some time now to do this and my truck has 94000 Miles right now. I do not think the filter has been changed so is it required that I changed the filter as well with 94k miles or is it good enough to just change the oil with the method mentioned here?

    Re: Transmission Fluid Change

    From what transmission shop owners tell me (shop owners) is that they have never seen a transmission filter that needed changing UNLESS the transmisssion had already failed and needed to be rebuilt.

    I never plan to pull another pan but just do this process about every 30K miles. I did pull the pan on the 4L80-e in the MH just because it was new to me and there was room for a fat man to fit.

    It had some mud in the bottom that was not going anywhere and the filter looked fine but after 20K miles/5 years the oil did not smell/look fine in a 5 gallon bucket BUT it did look/smell OK on the dipstick.

    From the one 4L80-e and two 4L60-e's that I have used this process on it has worked great. The 'new' Escalade had 102K miles on it and I did not pull the pan.

    If you are going to worry about it then pull the pan. If not then don't.

    Today I turned 60 and it seems like all my transmission issues came from running the ATF too long so with the bucket flush not requiring to get down on the ground I will just do it about every 30K and hope of the best.

    Let us know what you decide to do.

    Re: Transmission Fluid Change

    You turned 60 yesterday? Wow - Happy Birthday! Oh and I know what you mean about not wanting to get on the ground hehe. Yeah I think I'm gonna just do the oil flush procedure from this thread. I am probably gonna use the Castrol Dexron VI as well - Thank you for taking the time to respond!

    Re: Transmission Fluid Change

    UPDATE : I did Patrick's method today and wow it was easier than it looks. I used up about 13 Qts before I saw the bright clear fluid coming out in the clear hose. I then ran one more just to be sure. So 14 Qts in all. I noticed smoother shifting now especially from 1 to 2nd gear. Btw, I got Castrol Dexron VI on sale at Advance Auto Parts for $3.99 a Qt. not bad at all compared to $6.99 everywhere else! Woohoo finally done with all the maint on my truck

    I just performed this method of changing the transmission fluid and it seems to have gone very well. I would say 6' of the tubing is a minimum to direct the flow away from the car into a bucket, and a hose clamp on the 1" hose connected to the cooler is a good safety precaution. I'm not sure how much came out, but I've put 15 quarts in and I'm still below the hatchmarks for "hot" readings. I will let it settle over night, and keep checking the level and adding until appropriate level is reached.

    Re: Transmission Fluid Change

    I'll add this from AllData


    Automatic Transmission Fluid/Filter Replacement

    Removal Procedure




    Caution: When the transmission is at operating temperatures, take necessary precautions when removing the drain plug, to avoid being burned by draining fluid.

    Raise and suitably support the vehicle. Refer to Vehicle Lifting
    Place a drain pan under the transmission oil pan.
    Remove the oil pan drain plug, if equipped.
    If necessary, remove the bolts and position aside the range selector cable bracket for clearance while lowering the pan. It is not necessary to remove the cable from the lever or bracket.
    Remove the oil pan bolts from the front and sides of the pan only.
    Loosen the rear oil pan bolts approximately 4 turns.
    Lightly tap the oil pan with a rubber mallet in order to loosen the pan to allow the fluid to drain.




    Remove the remaining oil pan bolts.




    Remove the oil pan and the gasket.




    Grasp firmly while pulling down with a twisting motion in order to remove the filter.




    Remove and discard the filter seal. The filter seal may be stuck in the pump; if necessary, carefully use pliers or another suitable tool to remove the seal.
    Inspect the fluid color.
    Inspect the filter. Pry the metal crimping away from the top of the filter and pull apart. The filter may contain the following evidence for root cause diagnosis:

    Clutch material
    Bronze slivers indicating bushing wear
    Steel particles

    Clean the transmission case and the oil pan gasket surfaces with solvent, and air dry. You must remove all traces of the old gasket material.

    Installation Procedure




    Coat the NEW filter seal with automatic transmission fluid.
    Install the NEW filter seal into the transmission case. Tap the seal into place using a suitable size socket.
    Install the NEW filter.




    Install the oil pan and NEW gasket.




    Notice: Refer to Fastener Notice in Service Precautions.

    Install the oil pan bolts.

    Tighten the bolts alternately and evenly to 11 Nm (97 inch lbs.) .

    If previously removed, install the range selector cable bracket and bolts.

    Tighten the bolts to 25 Nm (18 ft. lbs.) .

    Apply a small amount of sealant GM P/N 12346004 (Canadian P/N 10953480), or equivalent to the threads of the oil pan drain plug, if equipped.
    Install the oil pan drain plug, if equipped.

    Tighten the plug to 18 Nm (13 ft. lbs.) .

    Lower the vehicle.
    Fill the transmission to the proper level with DEXRON(R) III transmission fluid. Refer to Transmission Fluid Checking Procedure and Fluid Capacity Specifications.
    Check the COLD fluid level reading for initial fill only.
    Inspect the oil pan gasket for leaks.

    Re: Transmission Fluid Change

    I followed the suggested method of removing the trans pan and had to use a pry bar to move the bracket out of the way. Thanks for the tips. I have another question though, if you fill the trans with too much fluid what is the easiest way to remove some fluid i.e remove the drain plug or is there a better way? Thanks again for the help.

    Re: Transmission Fluid Change

    Hello.
    Advice please.
    I want to check the oil level in the gearbox? The oil level must be measured with the engine running, or cold?
