3RD GEN AUTO TRANS FLUID CHANGE

I have a 2013 Tacoma Pre runner double cab. I went to the parts dept at my Toyota dealer and they sold me 5 quarts of fluid and a crush washer. I was going to change it myself, but I had other issues I needed to take care of. My dealer said they would still use the fluid I purchased from them and just charge me labor. They only used 3 of the 5 quarts. Either they up sold me on the fluid, or I got a half @ss job from the dealer on the fluid change. I've been trying to find out how many quarts is required for a fluid change but haven'r found any info. I'm going to call them back next week and ask how many quarts it takes. Either way I have an issue with them. Every video I've seen requires 5 plus quarts for a flush and fill.

 

You likely paid for a drain and refill. Not a flush. Two separate jobs that use very different quantities...3-5qts and around 3x that.

 

I have been considering adding one of these once I get some nicer weather to climb under the truck to do a drain and fill. Any experience or thoughts on it?

First time I’ve seen that kit. Don’t know anything about it. It would be nice if there were more pictures or instructions.

 

I'm about to do the flush...but still unsure about the correct cooler line to unhook and drain from. Is it the same one as the 2nd Gen DIY link? Just want to make sure I get the right one. Already messed up one part (over torque on the drain plug, so I need a new pan)... so hoping to avoid any other mistakes.

 

It'd be best to leave it alone, the pan drop when you replace it will get rid of tons of fluid.

If you are really set, its the 2 rubber hoses that lead to the trans cooler near the oil filter.

The oil filter itself has 2 coolant hoses don't touch those.

 

On the trans? I thought the filter was internal

 

That's a good point. Might just do that. There was a lot more fluid in the pan that I expected when I dropped it. Should still be able to get a good amount of new fluid in the system. I'll decide when I get the new pan.

Thanks!

 

I mean engine oil filter as a reference point.

 

Ahh I see.

 

Thread revival

Speaking of pan drops I need to do one

I'm about to snag a new pan from toyota, I'm back and forth on using liquid gasket or whatever part toyota uses as OEM

Grab some WS ATF (looking at aftermarket but decided I don't want to mix ATF so ill probably stick with partial synthetic OEM)

Anything else I need? I've heard the filter ought to be fine and leave it (should just be a metal screen)

 

I've heard the same about the screen filter. Imma throw some lubeguard as recommended by @gearcruncher. Does Toyota use FIPG for the pan? Supposedly the Toyota orange fipg is the shit.

 

Lubeguard is a great idea .
The Platinum works best with the AC60 series transmissions .
Grab a 10 ounce bottle and throw it in

$15 Lubegard 63010 Platinum Automatic Transmission Fluid Protectant, 10 oz.

I highly suggest soaking your pan bolts in lube a couple weeks before you drop the pan . Getting a lot of PM,s from members breaking pan bolts on the 6 speed auto . Make sure you have some never seize on hand to coat the threads before you put the pan bolts back in .
On another note , why not grab a pan gasket . They are only 5 bucks .
I hate scraping dry silicone off an aluminum transmission case.
If you guys are keeping your trucks for a while , using a cork pan gasket is going to save you some greif

 

Those 3m roloc bristle discs make quick work of that stuff

 

The hoses you referring to are the hose going to the trans cooler under the splash pan.

 

The system’s capacity is 10.6 quarts.

Each drain and refill will be approximately 3.5 quarts. HOW MUCH of the old fluid you’d like to remove depends on the number of drains and refills. See below.

• The first drain replaces 3.5 of the total capacity of the 10.6 quarts which is about 33% replaced.
• The second drain of 3.5 quarts will remove about another 2.2 quarts of the old fluid giving you about a 54% replacement at this point.
• The third drain of 3.5 quarts will remove about another 1.6 quarts of the old fluid giving you about a 69% replacement at this point.
• The fourth drain of 3.5 quarts will remove about another 1.0 quart of the old fluid giving you about a 78% replacement at this point.
• The fifth drain of 3.5 quarts will remove about another 0.7 quarts of the old fluid giving you about a 85% replacement at this point.
• A sixth drain of 3.5 quarts will remove about another 0.25 quarts of the old fluid giving you about a 87% replacement at this point.

This means it will take 6 drains, or 21 quarts, to replace approximately 87% of the old fluid. This is precisely WHY I perform ONE drain and refill [4 quarts] every 20,000 miles. Doing it this early means fewer overall drains than otherwise needed to keep the transmission void of very old fluid.

 

Ok, I want to do one flush by removing the inlet and outlet hoses and run the truck until I see fresh fluid. My truck has a 153000 miles and no history of fluid change and I starting to feel some tyranny issues

 

Just did this to mine today… did three drain and fills an used ~10 quarts. By the third time fluid was coming out pretty red, happy about it. Truck has 76k.

 

How did you do it, by draining from the the trans pan and refill it. Did you drive the truck after every drain or just move the selector and and drain.

 

Yeah, drained through the drain plug an adjusted through the plug with the standpipe. And both, drove the truck down the driveway an back an also cycled through the gears for about a minute. Took about 5 hours all together mostly allowing everything to cool down each time.
