Trans flush DIY

I think I am due...maybe overdue. What are the thoughts on this https://www.youtube.com/watch?v=mj5RrjpjDkU ?

 

You still need to make sure you have the correct amount. That method may work to a point but you still need to bring the tranny to the proper check temp. Then pull the overflow screw and look for a trickle.

Just follow the procedure in the sticky.

You may not even know now if your old fluid is at the correct level.

 

The You Tubers basic plan should work for either the A750E(2WD) or A750F(4WD) transmission used in the 2005-2015 4.0L, but there are a few things to consider:

- Looks like he is using Dex III equivalent fluid. You will need to source WS compliant fluid(assuming 4.0L automatic)
- He has a semi-large funnel - suggesting a dip stick. 2005-2015 have no dip stick - but you'll need a funnel and about 68"-72" of hose and a smaller funnel to fill from the top if you wish to go that route. I use 5/8" OD x 1/2" ID clear hose and fill from above. Some like to crawl underneath and use a pump. Filling from the top is a lot easier.
- The return line setup that you'll be using(assuming 4.0L automatic) will be different. Here's an A750x transmission cooler line diagram and another photo showing A750x transmission refill going thru the top:

Hose #7 is the inlet - Hose #8 is the Outlet

 

Video is for a 1st gen Tacoma. You can see for a split second he has a ATF filler tube through the engine bay - plus, he says so at start of video. It's a little more difficult on the 2nd gen as there is no filler tube in the engine bay. You either use a hand pump to add ATF through the filler hole (pumping out-adding two qts at a time), or a drill pump to fill up through the radiator transmission line. I used a

$18 Milescraft 1313 DrillPump300 - Self Priming Water Transfer Pump

Milescraft 1313 drill pump; others have used a lawn/garden spray pump. I read of another dude that ran a hose from the engine bay down to the filler hole and added ATF to match what came out when he started the car. It's a similar procedure I used on wife's Lexus ES350 cause the filler hole can be accessed easy through the driver-side wheel well, but looks more challenging on the Tacoma.

When checking ATF level, the fluid temp must be between 115-130 and truck must be as level as possible. An IR gun can be use - take the reading at the center of the pan. I've compared temp difference on my IR gun to ATF temp reading on my Ultragauge and the difference is less than a degree - check level at 120 degrees, and you cannot be off.

 

I believe the SuperTech is now formulated for WS replacement. However, you won't see me using that. I've flushed all my Toyota/Lexus products with Valvoline Max Life Dex/Merc - the one in the red bottle; $18 a gallon at walmart, when you can find it.

 

I was asleep at the wheel when I first started watching his video. He's doing a flush on a 1st Gen Tacoma - he mentioned '95 - '01. His technique will work but as I pointed out, the return line layout on 2nd Gen is different. I included a diagram.

For what it's worth, I've used Walmarts WS equivalent in another WS Toyota tranny for several years now. Shifts smooth as glass. I've used Toyota's WS, The Max Life product and the WM/WS product I just mentioned. Shifting and performance is the same in all 3 as far as I am concerned.

 

I love Valvoline MaxLife Synthetic ATF. Walmart practically gives it away in those 1 gallon jugs. It’s hardly ever in stock, people must buy the heck out of it.
