I'd like to install a heavier trans. cooler on my 2004, 6.0, 2500 w/3:73 gears...I have an elect plug thats capped off next to trans cooler,wondering if I can use this plug to power fan...looks to be 12-16 gauge, more like 16 gauge wires...but if its not there for elect trans cooler what would wire be there in that location for?

Been looking at Derale/jegs coolers w/elect fan attached to unit maybe 16" x 10"....my original trans cooler is about shoebox size,5x7 maybe...the larger coolers seem they would dramactically reduce air flow is reasoning to go w/electric assist cooler (fan).

If anyone has any ideas please feel free to respond back, my fittings seem to be threaded..does anyone know what diameter they'd be? Thanks in advance

Some have suggested that the fans prohibit air flow through the cooler when they aren't running with forward mounted fans. It seems like a legit concern.

I have 2003 quadsteer, I changed trans cooler to 11"x 8"and my trans now is 150 degrees, best item I have installed. I recommend.

Most seem to go with the Hayden 679 or equivalent, the factory cooler is to small. If you've got the factory auxiliary cooler, you remove it and just put rubber hose from the metal lines to the new cooler and you can either mount it on the A frame radiator support piece or directly to the condenser on the passenger side of the truck. Those seem to be the most common places. I used some flat bar stock from Lowe's to mount it in front of the A frame. Cut and drilled the metal to size and mounted it up.

 

If you don't have the factory auxiliary cooler, usually people cut the rubber hose going to the radiator and splice in their rubber hose. The bottom is out of the transmission, and you would put the auxiliary cooler after the in radiator cooler. If you mount the auxiliary with the inlet and outlet horizontal, the general rule of thumb is the inlet is on the bottom, if the inlet/outlet are vertical, it really doesn't matter.

I replaced my factory cooler (which was fin and tube) with a B&M stacked plate cooler and it made a world of difference, most notably when towing in west Texas. I cut the factory hardlines on the passenger side and double clamped hydraulic hoses to them. Not the ideal install I would have liked, but haven't dripped a drop yet, and coming up on a year. I should note that I also installed a WIX remote mount spin on filter mount (#24764) and WIX transmission filter (#51622). Should make my tranny fluid last alot longer.)

mount = Piece of angle alum from home depot. I brought a "Tru-Cool # 4454" trans cooler 71/4"x11"/3/4" around $55. Dont cut the oem line, just unhook clip and slip 3/8" hose with clamp. no problem over year, from

Thanks Brian, I didnt want to cut lines if I could get away without doing it...

I have an aftermarket transmission cooler and efans, no problems here. If you have them running off of the PCM rather than a temperature probe, they will be much more efficient.

I'm running the monstrous Tru-Cool 40K GVW cooler (8 1/2" tall x 22 3/4" wide) with a higher-stall torque converter, in Houston, with no problems at all.

Be careful with aftermarket coolers in northern states. I have a buddy that killed bushings in his trans due to cooler not flowing ATF very well when it was really cold out (-20F). In most GM transmissions, fluid thru the cooler circuit returns to be used as lube for bushings/bearings before it finds its way into the pan. Too much restriction means not enough lube flow means dead trans. Local garage that fixed my buddies trans says they see a couple every year...always during a really cold snap and always with aftermarket coolers. They've never seen any that fail like this with production cooler set-up.

 

Based on this, I'd assume southern states should be OK if aftermarket cooler doesn't block enough airflow to cause other problems ( high coolant temps or AC performance).

Good point. The Tru-Cool 40K comes in two styles for this very reason:

 

p/n 4739 (for colder climates - has a thermal bypass that warms the transmission fluid via the radiator)

p/n 47391 (for warmer climates - no thermal bypass)

      Lets Talk Z60 Suspension

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.

      I just spent the last 45K miles doing samples every oil change over more than a full year to get the data for seasons and break-in to broke in.    I found the same thing to be true. Something was always teetering on done or had stepped off the cliff long before the OLM was DOA. In fact, I found about a thousand mile difference between summer and winter. That is during the winter half the OLM was STILL too long. Even the severe schedule was to long in the winter.   Now having done the work I can say I was NOT DISAPOINTED. I saw nothing I didn't already know. Nothing my father hadn't already demonstrated in his 2K OCI's pushing dated iron on dated oils and weak filters to mileages well beyond 300K.   Building on his work through use of Lab testing it wasn't hard to find the correlation between 'sight/feel/odor, the things dad relied on, and test results. Use of current viscosity stable chemistries & filters has pushed that marker for my motors out to 3K summer, 4K winter.    So the early lies were 3K on conventional oil and the lie upon the lie was 7K+. turns out to be off by a factor of two.    So... it is true that modern chemistry has doubled the useful oil life. But the base milage that came from was off by double. It's how good lies work. Partly true, sometimes mostly true so that your meter isn't set off. It also means that non-shear-stable shelf oils are only now as good as the old oils were in their best case scenario.    So the question now is how do we improve on that? Thus the question into cleanliness among the other items listed in the post quoted below.    If this bores you, feel free not to participate.

      2027 Chevrolet Silverado: Official Discussion

      Is it though?  Like LTZ, not a high take rate.  Current Sierra has AT4, Denali and Elevation as its main bread winners.  Each trim accounting for 25-35% of sales for Sierra.  SLT makes up about 10-15% at best.        Like others have predicted here for GMC, it will be:   - Pro (equal to WT Chevy)   - Elevation (replaces SLE and SLT)   - AT4 (and X)   - Denali (and Ultimate).
