Transmission Temp

[06PullUouT]

Searched but no luck.... Is anyone running the scan gauge II and monitor tranny temp? If so, what is the normal range on the H3?

TIA

I have had mine up to 240 if I recall correctly...these H3s run hot though.

240??? dude that 20* away from completely cooked. Get an aux cooler.

Maybe that was the motor? It happened in bishop...

And run synthetic fluid. And no, Dex VI is NOT synthetic. You can get synthetic Dex VI, but the regular stuff isn't. Of course, I wouldn't flush my toilet with Dex VI, but that's another thread...

For Tans Temps 190 is optimum, 200-210 climbing hills, and 210-220 climbing hills in the heat.

With my new RonDavisRadiator/Aux Trans Cooler my Water temp doesn't get over 220 in the heat climbing Donner pass which means my Trans is running around 20* cooler (200).

Even for Water temp (240) that's pushing it. Keep in mind we have a 190* Thermostat. Just running around town in my bebemonster, the water temp stays under 210, usually runs 206, that's at low speed, climbing around these little foothills.

To the OP, I have an '06 and a scan gauge II - we have not been able to program the trans temp, but every thing else works no problem.

Ouch. I installed a 8" X 11 " trans cooler on mine just cause I tow a trailer occasionally. $60 cooler can save you about $2000.

I have an 08 3.7 and tow regularly 2T.

I was able to program my Scanguage II using X-Guage to read transmission temp.

Transmission Temp as standard was high @ 200 - 220. I installed an aftermarket cooler and now 190 is the max. (Aux Fan cuts in @ 180)

I am interested in that synthetic Dexron VI if anyone can pass any info I would appreciate it.

As far as I know, the scan gauge tranny temp doesn't work on the Alphas.

I need to install a trans cooler...and I have the trans temp on my I5...probably the only positive the I5 offers

Because I tow a lot I fitted the largest cooler I could find.

This is a Derale Racing Transmission Cooler with its own thermostat switch that turns on the fan @ 180.



I had to mount it vertically with the inlet/outlet at the bottom. I will see if I can find the installed photos and post them here also.

Not sure about the Alpha but you should keep trying the X-Guage. I googled and found quite a few codes and I tried them all but none worked. A few weeks later I tried again and after 4 or 5 goes I got one of them to work.

I've tried every combo under the sun, but none worked. I can't try anything more till I get back to the truck. You should post all the X codes you have found.

This is the one that worked for me............. Will post up the others separately.

it's the code for the Alison trans. This was per an email from scan gauge and from input from someone on another forum.

Thanks F5............ I put this in my 2008 I5 and it works great. (comes up in degrees farenheit but I am old enough to remember the conversion)

 

[M22KLARS]

How about this for a trans temp.....

 

[Chook]

I posted the complete list on CHO but looks like that went with the new forum. I'll do some more searching and re-build the list I had of X-Guage Codes for transmission.

 

[Chook]

Different Years & Models may have different computers.

The most common used by GM have either CANSF codes or VPW codes.

You can find out what protocol your vehicle is running with the ScanGauge by pressing MORE > MORE > MODE

I found out that the 2006 uses VPW. The code is

Trans
Fluid Temperature (Exc Allison)
6C10F1221940(01)
046205190640
3008
00090005FFD8
TFT
Degrees
Fahrenheit


The other one I posted above is for a 2008 I5 which is CANSF

07E2221940(01)
046205190640
3008
00090005FFD8
it's the code for the Alison transmission

As you can see they are both very close (only the first line of the code changes depending on if yours is VPW or CANSF)

Also the (01) on the end is optional. Try without the (01) first but if the computer doesn't have enough characters add the 01

Ok here are the details & the fit of this to an 08 3.7l H3

I used a Derale 13900 universal kit (purchased locally in Australia but comes from USA)

Here is a link to the same kit from Summit Racing.

http://www.summitracing.com/parts/DER-13900/

As I said above I had to mount it vertically rather than horozontal. (I checked with Derale & they said this cooler can be mounted any configuration that fits)

I only had to drill one hole to fit. I trimmed the top bracket on the LHS for clearance and replaced the bottom bracket with metal strapping. I relocated the horn to the other side.

I purchased different fittings/hoses so that should the derale cooler become damaged I could reconnect back to the OEM cooler.

Here are the photos of the cooler fitted:

Here are all the GM Specific X-Guage Codes

As you can see the only difference between CANSF & VPW is the TXD #

Also (Exc Allison) the only difference is one character in the TXD

Valvoline is listed as being a "fully synthetic" Dex VI. Whether it is truly synthetic, or simply made from hydrotreated group III base stocks like most "synthetic" motor oil, I don't know. Redline D6 is a true full synthetic that meets Dex VI specs. Personally I'm not a fan of Dex VI (polite way of saying it's total crap), but if you insist on using it the synthetics should do a better job.

Thanks Max.

When I put in my cooler I had a hard time finding Dex VI (and it was expensive). Not many people carry it here in the first place and I needed to top it up fast. Will look into the synthetics for the next change which is due soon and make sure I put the best in when I do.

Well, if Dex VI is hard to find and you really want the best, perhaps your local Allison trans distributor or big truck shop has Castrol Transynd or Mobil Delvac Synthetic ATF (NOT Mobil 1 ATF - they are different products). Technically, neither of these fluids meet Dex VI specs due to slightly higher viscosity (viscosity is similar to Dex III and most other ATF's), but they are superior in every way to Dex VI. The slight viscosity difference isn't an issue with the 4L60E, which was designed to use Dex III, and it works very well. It is a true fully synthetic fluid, using PAO (polyalpha olefin) base oil.

Thanks Max........Very useful information.

I particularly liked the MSDS on the Castrol Transynd which said it was suitable for top up (mix with mineral based oil).

A quick fleabay search even found GM endorsing Transynd (allbeit for Manual Transmission)

http://www.ebay.com.au/itm/7-QUARTS...r_Truck_Parts_Accessories&hash=item5d334c147b

Just highlights the DEX is just another way of making money out of a GM license (rather than real protection of the mechanicals)

Of the Transynd or Delvac is one better that the other (or is it the common base PAO that makes them the same)

I also found a Penrite SYN ATF in a Google search that may be worth looking into.

[Chook]

Scratch the Penrite SYN ATF............. I just checked out the MSDS and it specifically says "Not Suitable for DEX VI application" although it meets the Drain Life & Friction requirements.
