guzman's picture at the beginning of this thread, with the fittings in the side, is a very clean install. i like it.
regarding the hoses and the check valve... if you intend to skip the remote filter and keep the factory hoses (and they are not leaking), then drilling out the check valve and reinstalling it is the easiest solution. however, if you install either a filter or a cooler, and are need to replumb the hoses anyway, then go ahead and clip the hardlines and slip 3/8 universal auto trans hose over the hard lines, and eliminate the fittings. use a tubing cutter for a clean cut. use auto trans hose only, available at any parts store for about $3/foot. as much as 1/2 quart of fluid could run out of the radiator cooler. the external filter is a standard F8A or F1, the same as our trucks oil filter. you can change it as often as you wish, but do NOT skip the internal filter change about every year or two or every 24/36K miles.
as GD said - be very careful to plumb it correctly. if any doubt, place the hoses in a bucket and crank the truck and shift to neutral to see fluid flow. if you plumb it backwards, you'll burn up your trans.
here's more pics, including how ugly the top hoses are.

So I want to re-visit this topic. Here is what it looks like currently:

do I go with option 1 which ties into the pressure line?

or Option 2 on the return line?
http://www.flickr.com/photos/12758731@N08/10590163255/
Or am I totally off base.

definitely option 1. when i purchased the derale kit it came with instructions just to double check
also love the temperature port. wired it to a gauge and also hooked up another sensor on the return line to get a good idea of discharge and return line temps

confused:
on page 2 of this post HeyYou told me to add it to the return line. Page 3 indicates plumbing it backwards will burn the tranny up. Now you know my concerns on this issue. Additionally do i have my flow arrows correct?

according to GD, flow arrows MUST MUST MUST be correct. he accidentally plumbed his backwards and said the built in check valve in the filter prevented flow. i have not tried this. if you wanted to be experimental, try it. just put the end of the hoses in a bucket so you don't make a mess.
i don't think it makes any difference whether you put a filter in the pressure line or the return line. the flow and pressure is the same and the only difference is whether you are filtering hot fluid vs cool fluid and whether the oil inside the cooler is filtered or not.
i put mine in the pressure line to theoretically keep the cooler cleaner.

Yep, flow arrows are correct.
Option 2 looks good to me. There are a couple folks that have done this install here... not sure if there is a DIY or not.
Doesn't really matter which way you plumb it, but, the idea of filtering it before sending it thru the coolers (and thus, keeping that crap OUT of the coolers) sounds like a REALLY good plan to me. You will have a bit higher pressure going into the filter that way. (no pressure drop from the coolers, and additional line.) The return fluid just gets dumped into the pan anyway.
(I think)
