At $250 for a extra deep pan, I think the cooler is far better bang for your buck.[/quote]Meterpig wrote:So why did you buy a giant cooler if only to fight with the radiator.

Is that the standard universal pod from Auto Meter? That is exactly what I would like, that gauge and pod.LiftedAWDAstro wrote:Tranny temperature gauge installation. (these pics are from the SPB but the 03 was done the same way)
///So which line on the astro's (mine being a 97) is the return lineLaGrasta wrote:I just installed the very same Tru-Cool unit this past weekend. It was very easy and not nearly as messy as I thought it was going to be. Easily less than 2 hours tops.
Instructions called for:
Trans–radiator–TruCool–Trans
It was so much easier plugging into the lower radiator line.
Trans–TruCool–radiator–Trans
No harm from what I gather however I run the risk of not cooling the fluid to the max as the radiator may be adding heat before it feeds back into the tranny. Thoughts?
back to the trans mission 
(low pressure side)after it passes through the radiator top 
or bottom ????/ Steve Please advise

I even have a link on my mods list page for a decent place to get the Tru-Cool coolers. The 4490 comes with the correct adapters needed for the late GM fittings on the radiator so you don't need to buy those separate if you get one of the Tru-Cool's.
Definitely tap into the top trans cooler line at the radiator. GM only recommends installing the cooler after the fluid flows through the cooler inside the radiator. I have pics at the above links.
coming out of the radiator is that correct,every body I've talked to (Mechanics) 
seems to think that on most transmission that the bottom line is the return line to the transmission , [a Gravity thing]and do you think that my 97 would be the same as your 2002,also did you get your info. about what line was the return line direction directly from GM 
Well, If you read the thread through where I have pictures documenting the installation, you would see it is in fact the top line which you use. I looked in my FSM for the hydraulic flow and then verified the flow when the lines were used to flush old fluid out for fresh synthetic. It makes more sense to have the fluid remain in the cooler rather than flow back through the pump into the pan. This way you don't starve the valve body for fluid each time it's started. Most general mechanics really have no idea because they work on so many brands. If it was a veteran GM mechanic then you probably would get the correct info. Good luck with the install and take lots of pics!howso48 wrote:every body I've talked to (Mechanics)

/////////I'm trying to install a trans cooler in front of the radiator/ to do this I have purchased 2 barbed fittings , one that threads into the radiator and the other that threads into the line, My question is how do I undo as to remove the line at the radiator as it appears to look like a late model fuel line connection ??? we'll the line stay stationary (not twistLiftedAWDAstro wrote:It is a very easy job. I will be adding one to my '03 as soon as the weather cooperates. I am using a True-cool 11"x11"x1.5" stacked plate cooler. You will need to remove the grill and may have to make some brackets work. I did this on my 98. Here are the pics showing the location:

Remove the little clip and the tubing comes right out. It is sealed with an o-ring.
Or you can just spin off the fitting out of the radiator. Be sure to hole the soldered in fitting while backing out the male fitting or you may cause a leak.
([/quote] Be sure to hole the soldered in fitting while backing out the male fitting) it while backing the other one out to replace it with a barbed fitting ??? size does matter
