I have 2 friends who own tranny shops. They both said not to change the fluid unless it was getting brown and smelling burnt. They said changing it can cause proplems from loose debris getting in the tranny. I tow heavy and full time. Tranny heat is my biggest concern in my 05 Dodge automatic. I follow towing reccomendations and check all my fluids regulary. I also don't push the truck up hills. I let it find a gear and roll up the hill. I trust my friends who have about 60 years combined tranny experience.

Larry, you have a real pair of brass ones to sit there and say that your opinions are fact are mine are misguided. I am looking at the Helm factory service manual provided to dealers for the correct service and repair of GM vehicles.

Disconnecting lines is only referenced with regard to checking line pressure, checking cooler flow, etc. the same procedure is givenj on page 7-575 for the 4L80E.
granted my manual is for 2001 vehicles and may not be applicable to the OPs 2010 Silverado, but certainly no less appliacble than your service knowledge of your Ford vehicle.
as a reminder, this is a public forum and for you to indict my opinions has dangerously misleading while canonizing yours as unimpeachably correct is the height of arrogance and ridiculousness. You must not have many friends.
Well this is the first time you have even hinted at what you used to reference your posts and I will only remind folks that in your first post your were flat out wrong on the % of fluid changed with a pan drop and fill so that tells me you are loose with your facts to start with. I also provided "FACTUAL" info with even page and reference on the statement made here that GM manual specifically says not to FLUSH the Transmission and that came directly from a 2010 Silverado manual. Not to your reference to your 2001 manual, you should IMO have stated where it came from since who knows if that procedure is applicable to this particular year and model since again you don't have the current facts for the specific model you are talking about. As far as me mentioning the procedure for my 2001 Ford, I specifically mentioned in my very first post IIRC that I didn't know the specifics for the GM trucks, but one should be similar so I didn't in ANY WAY base my information solely on that vehicle only. In using your 2001 service manual and ASSUMING it is exactly the same as what is applicable to the 2010 Silverado in this thread is IMO even a more flagrant playing with the facts as it might apply here. A simple google for Silverado tranny fluid changes will show to anyone interested that what I have been describing and even doing the type of flush that I don't think is prudent is common and even used by dealerships and I would submit that MOST dealerships and tranny/service shops do much more than a simple drop the pan and fill, with most using a tranny flush machine and I won't go there since that is a whole other topic for discussion.
I would highly encourage folks to go back and look at my first post in this thread and the misfacts stated by you and what my reply was and exactly what I said which your most recent response has seemed to TOTALLY IGNORE. I have and will continue to contend that your asseration thatit's more valuable to drop the pan and change the filter than it is to flush 100% of the fluid. You will have 3/4 of the fluid replaced by dropping the pan, and the remaining 25% of teh old fluid won't hurt anything
is flat out wrong, not factual, and not supported by any reputable source. NOTE: you used flush which I have issues with and take that as meaning changing 100% or as close to as possible which I do agree with.
Your taking this to the personal level with digs as to who and how many friends I have and to lighten up, and using terms like arrogance and ridiculousness w/o specific reference just tells me that is generally what happens when one in faced with the embarassement of admitting they are not correct and the only way to save face is to take it to a personal level. That is IMO TRULY SAD. I'm GLAD as CKNSLS sees my point even if you and some other seem to want to ignore the facts and common sense. I will not you still haven't substantiated that outrageous statement about it not being advisable at times not to change as much tranny fluid as possible.
I just love it when folks try and dig themselves out of a hole and fail to realize that they are only making the hole deeper and deeper:p
O.K. all good things have to end and I'm not childish as some on insisting to always having the last word in a conversation so I'm THRU here since I think I have made my points to those that want good information and if one wants my specific input any further on this particular topic, please PM me since as I said I'm THRU with this particular thread.

They say to never change the trans fluid ????? when did trans fluid last for ever ??? Maybe the manufacture would rather sell owners new transmissions in a few years instead of a couple gallons of trans fluid ???? I don't care what the manufacture says my trans fluid is getting changed regularly !!
Yeah, it's dumb. My last 2 work trucks, '11 F150 and '13 F250 didn't have a dipstick. Neither does the 06 Charger we got last year.
It's getting changed soon even though the reccomended interval on it is 100k.
Is your 2013 F250 a gas or diesel? My diesel 2013 has a transmission fluid dipstick. (refer to page ~313 in the owners manual)

2010 Silverado Owners Manual and the manual has the part number of 25854757 A First Printing.
I converted this document to a PDF and then did a FULL search on the word flush and what it does say not to "FLUSH" is the engine oil, but does say to "FLUSH" the cooling system.
What is does say on page 6-23 isAutomatic Transmission Fluid
(4-Speed Transmission)
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission fluid
level is when the engine oil is changed..
Change the fluid and filter at the intervals listed in
Scheduled Maintenance on page 7?3 and be sure to
use the transmission fluid listed in Recommended
Fluids and Lubricants on page 7?13.
A similar procedure is found for the 6 speed auto on page 6-26Automatic Transmission Fluid
(6-Speed Transmission)
When to Check and Change Automatic
Transmission Fluid
It is usually not necessary to check the transmission
fluid level. The only reason for fluid loss is a
transmission leak or overheating the transmission.
If you suspect a small leak, then use the following
checking procedures to check the fluid level. However,
if there is a large leak, then it may be necessary to have
the vehicle towed to a dealer/retailer service department
and have it repaired before driving the vehicle further.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7?13.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance
on page 7?3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricants on
page 7?13.
Please note in both these they say "FLUID CHANGE" and what I have described doing with with the tranny itself or with the proper machine is exactly that a "FLUID CHANGE". It's not as is normally referred to as a "flush" nor is it a "drop the pan" and fill so what I have described is if you want to follow the owner's manual the closest you can get to a "fluid change". As I have already provided documentation that simply dropping the pan and refilling only changes 5 of the about 12qts in one Chevy tranny and I don't call that by any stretch of the imagination a "FLUID CHANGE". If you do O.K. have at it, but realize what you are actually getting and accomplishing which like one member that thought that got 75% of the fluid changed was way off in his numbers and is basically like the example I gave is doing an engine oil change and putting most of the old oil back in and only adding very little (i.e. less than 50%) new oil.
I leave it to the Chevy owners to figure out the best way to do an effective "FLUID CHANGE".
45Ricochet and 352 your posts are IMO not helpful and do nothing to help or add to the topic being discussed here and I am at a loss to understand why folks like you post the useless type info that you do. I think you should be here to help folks and leave whatever personal agendas and what I can only call "childish" comments such as "Personally I only flush when going #2" you might have at home where they belong.
Finally the apple and oranges statement is questionable here since regardless of make transmissions in their cooling systems are very similar and all have a line out which goes thru the coolers and then a return line in and what I have described for my 4R100 is disconnecting the return line and letting the pump in the transmission push all the fluid thru the internal passages in the tranny and the TC and collect that fluid from the return line, replacing the lost fluid via filling the pan before it runs the tranny dry. This procedure or something very similar should be applicable to many other makes and models of transmissions, but one needs to consult the people actually knowledgeable to get the specifics which at this point no one that has posted in this thread including me has shown that specific level of expertise.

The reason I said go talk to a transmission re builder at a dealership is because what ever I say there will be many who will not believe me. So go hear it from one who knows. I know exactly what happens when you ( FLUSH ) a transmission and I will never do it. When you spend $2500 plus several thousand miles after you ( FLUSH )
You will be thinking about how helpful this post was . So do what you have to do and pay the piper later. I'm finished on this subject and good luck to those who ( FLUSH ).

one more comment and i am done here. if you want to talk about opinions and misconceptions, comparing transmission fluid to motor oil is one such. a 100% fluid change is not always advisable nor beneficial as it is with engine oil. Do some research on that...provide YOUR cited references that state that it is advisable to change 100% of the trans fluid. dont assume that it is obvious.
also regarding the flush...my buddy that owned a six bay shop had a trnsmission service machine that was basically two tubes that got inserted down the dipstick tube. Fresh fluid got pumped in one tube, old fluid extracted via the other tube. still not sure how it didnt just suck up the new fluid coming out of the hose right next to the pickup tube.
lastly, ligten up larry, life is too short. go camping! for me, looks like i have to go back to using my block list.....
