Come along with Eric O. as he does some routine maintenance on this 2003 Chevrolet Trailblazer. NOW, we all know that dropping the pan and replacing the fluid in filter DOES NOT replace ALL of the fluid. This is normally done as a scheduled maintenance about every 30 to 50k depending on what the customer wants. IF YOU WANT ALL of you fluid replaced it should be done with a fluid exchange machine, however in my experience doing periodic maintenance such as this has proven useful time and time again. Be sure to consult your owners manual for recommended service intervals on your vehicle and for fluid type

Dont pay attention to those trolls they have no lives with nothing better to do then criticize other people! You my friend are the special forces of mechanics the best of the best! Anyone that knows anything about mechanics would know that! I think its a great idea to not remove all of the transmission fluid so that the new fluid will blend with whats left in transmission especially with vehicles with higher miles! Ive seen a lot of people have problems with transmission flushes ( me being one of them. havent heard of any problems with just a fluid and filter change with proper maintenance!

Ok. Im driving a 2002 chevy trailblazer LS. Transmission or solanoid issues. I'd shift it into drive. . Nothing. but once I put it in 3rd it worked for awhile. then soon it gave out. . So i bought a filter kit for it and replaced it. Shit just got worse after that and the rear wheels locked up. Not even nutrual worked. So i had it forcefully toed back to the house. Can u please help me with a tip or two? Im low on funds. Is why im not taking it to the shop. Im at 575-921-4455 and ask forLucas. That's me. Thank you for taking the time to read my comments.

Theres a big difference between a professional that does this every day for a living such as Dr. O and knows all the tricks to save time and headaches and someone that does it once in awhile. You will learn far more from hands on experience then you will ever learn in a classroom! Dont pay any attention to those trolls anyone that knows anything can see you are a great detailed mechanic that do things the best way that you know how and keep up the great work!

Ive check around my area and a lot of shops wont do a spill N fill, theyll only flush out the old fluid and put new in. But my car has 140k on the original transmission and I have had the fluid changed every 30k (as recommended by the manufacturer) but my filter has never been changed. So watching some of your videos and others have made me decide I think I can handle changing it myself when its due. Ill be sure to torque the pan bolts to factory specs.

In your opinion is right on the money. the flush the service writers sell is so much better. NOT!
This is the only way to service a transmission.
That is why i never change the seal if its good.
Found the video, not what i was looking for, but what the heck, cant watch all the vids all at once. Have an 04 with no go ahead gears.
I use high tack as well.
Guess im a hack too.

Hi guys! Thanjy for the vid!
Question. i own the 03 TB LTZ but i'm from Germany and the TB is very very rare. maybe 500 in whole republic so geting spareparts is really challenging. at time i get my parts from online stores like rockauto. so my question, is the pan-gasket any similar to other Chevy-transmissions? Tahoes are very popular here. could it fit maybe?

Totally agree all that flushing is unnecessary. I've had several cars and with regular spill n fills they go 300K and still work fine when I dumped the rust bucket. Even the wife's dreaded dodge caravan trans has 255K no issues. My kid's mustang did have its first change at 116K and was pretty dirty. So I did three changes. 100 in fluid but we'll be good for years.

Hello. Thanks for posting the video. I enjoyed watching it. My transmission shifts great, however i have the transmission flush done as part of the preventative maintenance, and not as a last ditch effort to try and fix something that isnt working well. The story Im telling myself is that if its working well than the pm should help let it working well.
reply

I believe you are following the correct procedure by changing the fluid and filter. I have been advised by a reputable mechanic to never flush your automatic transmission because there is a chance that flushing it can cause small particles to stop up some of the small holes and cause major issues.

First of all I'll say there are a difference between there and their. I don't know why people use there when they are talking about their. Okay with that being said. nice video man. Don't be concerned with what people say be more concerned about who you are, have a good day dude
