Figure for those not so familiar with auto transmissions, cooling is the critical thing to making your unit living long and truble free.

Much after 230degrees F the seals begine to harden and shrink, if you tow more then not, you want agressive cooling.

Even with this cooling you still get wear and tear,, Inside the tranny there is a screen if it blocks you are in need of a rebuild, another way to say it is this screen does not remove fine contaminants, eneter now the Parker LFS Automatic transmission filter!

It removes down to 7 microns nominal with a 5micron beta, what does that mean? It means you are not circulating liquid sand paper through all those fine orifices and delicate O-Ring seals and best of all keeping the cooler clean to do its job.

MOD: With the filter in hand take it to a good machine shop, have them drill 2 hols on the top flats of your filter (Or if room just use the other side and bush down the threads) and tap to 1/8 pipe.

On the incoming side put a 10psi switch, it will close on rise (As the pressur gets higher the switch will turn a light on) this is the change filter indicator.

On the out going side put in a transmission temp guage (This will usualy read higher then the transmissions body temp as we are measuring the fluid off the torque converter, this is what will tell us when we need to change the fluid over the usual schedual, hotter the fluid the sooner it would be wise to change it or take a sample and have it tested by an oil analisys company.

Pictures will follow when I have them.

Now that is just downright fancy.... but I have to admit that it is a great idea. :D


Good thing you mentioned that pics are coming... otherwise you would have gotten flagged.
Excellent Post!!

Having a modern truck. I am running Torque app on Android with a bluetooth adapter on the OBDII port to monitor my trans temps. I would say the factory tow package/cooler is doing a good job since I have never seen it over 208F (pulling up the Coquihalla) however extra filtration is on my to do list

well I monitor both trans body and fluid, the fluid is the real trick as leaving the torque convert it can be well over 300f, being mine is non locking it stays in the uppers like that so for me I need to be super agressive, since doing the trans cooler it stays below 150 when driving normal (Befor was in the upper 180-190s)

but the shock was when I learned the trans filter was really a trans screen was when I started to research much better filtration. and I am big on efficiency, as I don't like to waste money changing a filter that needn't requier it.

the internal by pass opens at 15psi, so with an adjustable switch set to ten psi gives you a good head room for filter life, these where built for ambulances and such so should last many towing miles.

still trying to find a camera to borrow.

well with any luck next 3 days I'll have some pictures!, I just drove 400Km with max load over randome terrain, trans never got over 180 degrees ferihn, no leaks at the filter and the filter was pretty evenly hot.

So all mods turned out a massive success, and feels so nice with fresh trans oil in there!
