I recently purchased a scan gauge 2 for towing a travel trailer, I tow in 3rd with the tow haul engaged. My temp shows around 150 when not towing and around 80 when towing. Sounds kinda backwards to me. Mine has the xgauge so I had to program it to check the tranny temp. If anyone has one of these let me know what yours registers. I might be returning this scam gauge back to where I got it.

The tranny temp is lower when towing? That is definitely weird.

makes me wonder if it actually works.

I haven't towed anything since I installed it at Christmas so I can't compare the temp between towing/not towing, but everything else seems to work fine. I also programmed in a few different guages on the Xguage and they all appear to work correctly also. Maybe yours is defective? Have you tried deleting the Tranny temp xguage and reprogramming it?

Wow, your scan gauge acts as a tranny cooler as well..... :chevy:

I wold like to here what you find out, I have been thinking about getting a scan gauge for some time, but if the trans temp does not work right then it is not worth it to me.

so you're stating that you can drive around normally and get a tranny temp of 150, then go and hook up the trailer (same day with same weather conditions and temp outside) and put the tow/haul mode on and continue driving for a while and the temp drops to 80? Does it start dropping slowly as you drive, or does it imediately jump down to 80 as soon as you switch the tow/haul mode on and start driving? A little more info please

Joe, I will have to agree with everyone else. Something is wrong. You may come close to holding a similar trans temp when comparing towing and not, but it certainly will not drop like what you have seen. I run an Interceptor Scan gauge and monitor my trans temps with it when towing.

I am going to try to delete it and start over. It does not fall automatically, it is a slow fall to around 75-80. I drove it today(not towing) and it is around 167 so who knows. I will try again and keep you updated. thanks

Yeah it was the same conditions and temp outside , I pulled it in 3rd with the tow haul and it slowly dropped down. I see there are 2 codes for the xgauge for the Gm , a CAN and another I cant recall right off hand, which one did you use?

I have a scan guauge and my regular temp have been in the 113-114 range(winter driving mostly the outside temps in the 30's-50's), and when towing it went to the 140-150 range. So my scanguage, temp guage seems to be working. I also have a 4L80 in my truck so the temps are lower. I seem to see that the 4L60 do run in the 160-190 range.

I used the settings in the list under GM VPW, not the CAN

my tranny temp guage programming starts with 6C10F122194001 for the TXD setting

I have the 4L60E and am using the ScanGuage II. I normally run between 102 - 130. When I'm towing it climes to 140 - 160. I have not seen it go higher. However, I also bypassed the radiator altogether and installed a rather large tranny cooler. :shakehead:

Anon, not trying to get in your business but from all of the research I have done, I have never found one recommendation to bypass the internal cooler. This is especially true in very cold climates.

 

I too have a stacked plate cooler that is twice as big has my OE cooler but I still let the fluid go through the radiator first and then through the aux cooler. I live in the deep south so I do not have to worry about low outside temps as you do.

 

It is your truck but I would suggest you do some research on this and consider re-routing your cooler lines to go through the radiator first.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
