Advice please.
I have a 2004 4Runner with 175,000 miles.
What do you think about a transmission flush?
Coolant flush?
Differential flush?
Other maintanance? (I have done regular oil and filter changes and a timing belt change at ~100,000.

Please read stickies on this forum. All your questions were answered hundreds of times. Search is also your friend. And, yes you need to change all of those fluids if it hasn't being done on record. Welcome to the forum.
 
Very common question. Read stickies and google is your friend. Basically with that amount of miles, do a low pressure flush on the transmission-google. Ok to flush the coolant and swap out the differential fluid. Just be careful with the transmission.
 
what do I think of those things? Yes, do them. Not very hard, just a little tedious in some cases but your truck will run well for a good long while.
 
If it has never been done, you do not want a high pressure flush that you get at dealerships. It will kill your transmission. If you start out with the high pressure flush say every 50k miles, it is ok. What you want is a low pressure flush, can be fairly involved so google.

Yes change out all the fluids.
 
I would consider doing the services recommended at 90K: coolant flush, transmission flush, oil change, new spark plugs and wires, and a new air filter.

This advise is good except for a high pressure transmission flush that all dealerships do. If you wait til 90k, there is a good chance you will dislodge varnish and cause all kinds of problems. High pressure needs to be done at about 40 to 50 k miles.

Low pressure flush can be done at any time.....
 
Is there hope?

Hello all,
Went out and bought some grease guns today to grease my driveline and thanks to the forum it has been going well. Today, things have been a little strange with the truck. I have an 05 v6 4x4 and I’m worried that what I may have been diagnosing as a driveline clunk may actually be a transmission issue. Today I had to brake hard from about 50 mph to avoid hitting a car that had stopped in front of me. After hitting the accelerator to get going again the car reved up high and then chirped the tires about 1-2 seconds after I had pressed the accelerator. It’s never done this before. I checked my records (I had the transmission drained and filled less that 5,000 miles ago) upon looking at the form from Toyota it seems that i was only charged for 2 quarts of 00289-atfws @ 10.49 a piece. Is my transmission fluid just low or should I start looking into a rebuild? Should I flush it and hope for the best? Or just do a correct drain and fill with the correct fluid amount? Could this be a driveline issue and my transmission is fine?



Thank you for your time. I appreciate any and all feedback.
 
Don't forget brake fluid and power steering fluid. I recently flushed power steering fluid on a 2007 Jeep grand Cherokee using the engine off method. It was easy.

I did it slightly different than the video. I unplugged the factory line from the power steering cooler to reservoir. Raised it above the reservoir. Connected clear hose from the power steering cooler to empty container on the ground. On the Jeep Grand Cherokee it took about 2.5qts to flush the system.
