Glenn and Aaron, that's good to hear on the temps. It's probably a case of where I saw hotter temps than I expected and started to get a little worried, but they've obviously been there the entire time I've had the truck and I've never had any problems, so I'll just go with it. I'll put a bigger cooler on there like the Tru Cool for good measure, but after that I just won't worry about it

It turned out better then the mare install, that's for sure. I wish that sexy ic worked better because I can still get it hot. You never told me Aaron, did you make use of the 99 ic?

The temps I talked about are from the scan gauge I got, probably reading off the pcm like you were saying.

If that is true case, you may want to install a true gauge. There was quite a bit a difference between my monitor in the analog gauge. It stayed close until the Edge hit 160...the gauge read 180! A least I know now. I had my gauge installed in an hour. Wasn't bad at all.

Byron, my trucool is between my IC and radiator. Hottest I've seen was 205 (that is not a dangerous temp), that was in high wind and 95*outside towing in OD. They work. They come with 3/8 fittings and out trucks have 5/16 lines. I wouldn't bother with the warm-up bypass. I don't think it gets too cold where you live.

I just didn't think it would be a 25* difference. Anyone? Thanks.
Where did you put the sender for the gauge?

In my experience watching the temperature as reported in the PCM (that's what the Edge is going to show you) is that it is +-25F from a sender in the test port on the side of the trans. Usually it was +-15F, but sometimes would get to the higher difference. And notice I said plus OR minus, the difference could go in either direction, depending on whether the trans is heating up or cooling down.

If your sender is in the line to the cooler, expect a MUCH larger difference in temperatures.

I built the line. I hate to have anymore soft line than I have to.
If you have access to a tuning bender just get a piece of iirc 3/8 brake line and a couple cushion clamps.

Wow Darin, I haven't seen those temps. I must be worrying over nothing. Sounds like the TruCool is the way to go. If anything, it will be much bigger than the cooler I have on there now.

Mark, thanks for chiming in. The sender for the gauge was put in the test port on the driver side of the transmission. And the temps I am seeing our 25* greater than what the Edge showing me.

Thanks broseph. I'll look into it today.

I build my own hard lines too. I got a set of genuine used Made in USA Swagelok benders on ebay for a small fortune. I've run SS instrument tubing in the past so I have some practice at it. Lots of fun figuring out the bends and lengths and I sometimes have to make a line twice.

I know I got some pics of the cutting...not sure about the install though

I have a Tru-Cool 4739 that I'm about to install, along with an auxiliary external screw-on-filter kit and a change-out of the 20-year-old factory hoses. Two questions:


1. Any problems if I leave on the factory external cooler in the system for additional cooling?


2. How does one accommodate the 3/8" Tru-Cool line size with the factory 5/16" size? Can the 3/8" hoses be used on the 5/16" factory hardlines by using clamps, or what should be done to make it all fit?
