4R100 adding external inline bypass Filter. Good or Bad Idea?

[tdeal823]

Ok I searched and could not come up with a good answer. I'm getting ready to change all my oils in the truck and I am going to add a second cooler and maybe a filter.

Questions.............
What do you guys think about an inline filter for the 4R100 Automatic Transmission?
wix makes some tranny specific stuff. What's the flow rate of our tranny lines?
Do I need the bigger one for the flow rate?

the smaller one(#1) will fit on the inside of the frame rail away from any road hazzards. The bigger (#2)one is BIG 7" long filter and the base is 2". Might need to put that up by the cooler?


Setup 1) Filter # 51624. This filter has a bypass valve setting of 13-19 psi, and a micron rating of 19 (the lower the micron rating, the smaller the particle it will trap. I don’t think this will be a big consideration for transmission applications however, and both of these filters will be more than adequate). The filter is 4.3” tall. You would use mounting base # 24764 for this setup. Here are prices and specs:
7-9 GPM FILTER
51624 - $8.62 Part Detail

24764 - $22.69 Part Detail



Setup 2) Filter # 51158. This filter has a bypass valve setting of 18-20 psi, and a micron rating of 32. The filter is 7” tall. You would use mounting base # 24768 for this setup. Something to keep in mind is that this filter is going to take 1.29 quarts of transmission fluid to fill. Here are the prices and specs:
12-16 GPM FILTER
51158 - $7.70 Part Detail

24768 - $24.68 Part Detail

FYI, BTS doesn't recommend a additional filter. IMO we don't need additional filters anywhere.

*IF* you must have one, I personally like the dieselsite setup with the external pressure gauge.

I don't like the idea of external filters due to soooooo many people having poor maintenance habits. A clogged filter is a sure way to kill a trans. I also wouldn't run a external filter on a BTS trans.. it just doesn't need it. If a BTS trans fails, Brian will just take of it.

I just figured it would be good piece of mind.
changing engine oil every 3-5k
Fuel filter every 8-12k (every other oil change)
coolant and trans filter (every 4th oil change)
I guess if you guys think its a waste than I will not worry about it.
I will just pull the pan and the torque converter plug and put new in and be done.

I would have thought the same thing but I keep reading its bad so I just dont do it.

Well, it isn't BAD until the filter gets clogged and messes with line pressures and in turn restricts volume.

Otherwise, it's good.

couldn,tyou set it up so the fluif runs thru it(some of it) some still continues on its original path? so if it clogs no big deal. It will just run its original course. Like tee it in and out. make the line y into 2 lines.One thru filter and the other not. Then a Y bac into 1 line. Same way a coolant filter is on a 6.0 from dieselsite. same idea??

I'm going to be using a wix filter and mount.
51622 trans filter it has a built in bypass at 9psi
24762 is the filter base.
I will also be installing 2 30 psi gauges one before one after to monitor the filter
I will post up pic once I get everything all done.

The kits from dieselsite have a by-pass so that the trans fluid will still circulate in the event that the filter clogs or otherwise fails.

With that in mind, would the external filter offer better protection, or does the possibility of a filter WITH by-pass still allow the possibility of a restricted volume flow????
