Tranny loving

Now that I’ve got your attention with the title might as well stay and see if you can help me out.

I plan on adding a transmission filter and cooler to my 1999 Tacoma 3.4 with the 4at ect 2wd transmission. I plan on using this Hayden cooler

$51 Hayden Automotive 678 Universal Rapid-Cool 9.5” x 11” Add-On Transmission Cooler – Not for Direct Replacement of the OE Cooler

And this derale Mount

$47 Derale 13049 Side-Ports Filter Mount Kit (3/8" NPT)

https://www.amazon.com/Derale-13049-Side-Filter-Mount/dp/B00GN6XCAU
With a Ford fl1a filter.

Does anyone have any input on the derale mount ? I’ve never heard of the company but through my searching of the forum they seem to be a pretty commonly used company for the same thing I’m trying to accomplish. Also any other suggestions on a better filter then fl1a or does anyone know if my Toyota 90915-yzzd3 filters will work with this mount ? I know derale says the mount will work with a Fram ph8a( junk)

For the cooler I’m planning on totally bypassing the factory tranny cooler in the radiator. Any cons to that besides maybe a small loss in overall cooling if I where to leave it connected.

Last question and the most important one will adding all these extra components and lines result in any issues with loss in transmission pressure? Or cause any extra strain on the transmission pump ?

 

If you bypass the stock cooler, your transmission fluid will take a lot longer to warm up. The stock "cooler" also acts as a heater in cold temperatures.

 

That’s good to know I was unaware of that. So do you think it would be better to run the cooler before or after stock radiator cooler. I don’t really ever experience colder temps but I do see how that could be beneficial during my short drives to work in the morning

 

Mine goes like this:
transmission > stock cooler/radiator > aftermarket cooler > transmission

@gearcruncher recommends this

I used a tru-cool low pressure drop cooler. It won't run the fluid past all of the fins until it gets to a certain temperature.

I went with the B&M 70264.

Here's a video of the install. I ran mine like @nzbrock.

I did mine the same way as above. At least from what I've seen, most people generally don't add another filter in the mix.

Some people fear the "pink slushy" or whatever (coolant and lube mixing from a bad radiator), and that's why they bypass the stock cooler, but I've never encountered that, so I figure leave well enough alone and use the aux cooler for *additional* cooling.

 

I run the derale mount and Hayden cooler on my 2nd gen

 

This is not what I expected after reading the title of the post...

 

Got your attention though didn’t it ha


So I’m starting to look into the long tru cools now that you guys have suggested it. I’m assuming they are superior to the Hayden due to the internal pressure regulation feature ?

 

I run a B&M T cooler on mine with a spal fan.

Trans->factory cooler/radiator->Aux cooler->trans

Best thing ive done for keeping temps down is to get a scanguage so you can see the temps and drive the truck a certain way to keep the temps down. EX) o/d off while climbing hills if the trans unlocks building heat.

Crawling is harder but the fan helps and also keep it in 1

side note: Alot of the external coolers have the feature where it doesn't go through the fins if the trans fluid temp isnt hot enough.

This is the exact thread that helped me.

 

And you guys are welcome to add as much info to that thread as you wish , I made it for the members

 

I definitely would like to get scangauge at some point in near the future mainly for the tranny temp monitoring I need to see if they are capable of doing that on my year of truck

I’ve been looking for something like this thanks. I guess it would help if I searched somewhere besides just the first gen forum

 

So I see from your first post on that you went with the 4454. Did you have any issues with smaller 11/32 barb using the 3/8 hose. Everything else I’m planning on installing uses 3/8 along with the factory cooler(I’m pretty sure but could
Be wrong). I know 11/32 is only about .030 smaller then 3/8 but just curious how it worked out for you. I’m eyeballing the Tru-Cool 4544 since it uses the 3/8 barbs. It’s also just about twice as much....

 

The hose that comes with the kit fits perfect on a 3/8” barb..

 

The fact that you clicked though makes me wonder why you clicked if this is not what you expected.... However, I guess i shouldnt throw stones, cause I clicked.

 

Hey, don't judge me!

 

Not judging. I clicked the title and I liked it.
