Cold Climate Trans issue

Calling all cold climate transmission gurus. I have a friend who has a 2006 Chevy Silverado 2500HD CCSB. He has a "built" trans with welded input/output shafts, 1200 rpm stall converter, modded valve body, MagTec deep trans pan, etc, etc (appx $5K in parts alone). No performance mods other than intake, exhaust, down pipe and bully dog programmer.

Recently he walked outside of work to start his truck and shortly thereafter it went into high idle due to the -35F outside temp. He says that he went back into work to finish up something and when he came out trans fluid was everywhere.

Before we go into discussing the fluid issue I want to state that I have a 2007.5 Silverado 2500HD CCSB (Skyjacker lift, 35's on 17's, intake, exhaust, downpipe, and EFI Live with DSP5 by Duramax Tuners on a pretty mild tune).

Living in Alaska we see as cold as -60F winters and lots of snow. A standard winterization of our vehicles is to have antifreeze mixed to -50F, block heaters, oil and trans heater pads and trickle chargers for the batteries.

My buddies truck with all the trans' mods and the MagTec deep pan only has one heater pad (on the side of the pan) and its only like a 80 watt pad whereas mine is like 150 watt.

He thinks he lost all of his trans fluid because he has all those mods to his trans and that the high idle kicked on causing him to blow a cooler vent pipe.

To me, his explanation doesn't make sense because I have yet to have an issue with my truck. Nor do I know of anyone up here (who has been here for awhile) have that issue. I think he just needs to upgrade the size of his heating pads or at least have one on each side of the MagTec pan.

He is convinced that he has blown the Torque Converter and maybe grenaded the transmission. As is, the trans is out and will be headed to the shop in a few days.

Please feel free to chime in, I would love to hear any comments or questions or explanations.

Was this ever done?
Campaign-TCM #07293A Transmission Overheat in Extreme Cold Air Temperatures-Reprogram TCM -
Equipped with Allison 1000 Transmission (RPO MW7); Duramax 6.6L Diesel V8 (RPOs LLY/LBZ/LMM - VIN 2/D/6) Engine Located in Alaska and Minnesota; Canadian Yukon Territory, Northwest Territory, British Columbia, Alberta, Manitoba, Saskatchewan, Ontario,
Quebec, and Newfoundland.

Your friend is most likely correct.
Torque converters were blowing up and this TSB was the fix?
Did he have his block heater plugged in?
What oil did he have in his trans?


As for the TSB on Transmission issues when using hi idle. The issue was that a number of 06 trucks had Allisons filled with GM's DEX VI fluid.-34C and colder temps, the trans fluid was very thick and unable to properly flow or lubricate the torque converter. The TC is engaged during hi idle. As such there were a significant number of failures of torque converters while guys were warming up their trucks using hi idle. The fix or solution was to ensure the transmissions were filled with a TES 295 fluid and most went with Transynd a Castrol product that is fully synthetic and capable to well below -40C (F).




#07293C: Customer Satisfaction - Transmission Overheat in Extreme Cold Air Temperatures - Reprogram TCM - (Feb 16, 2009)

Subject: 07293C - Transmission Overheat in Extreme Cold Ambient Temperatures - Reprogram TCM
Models: Certain 2006-08 Chevrolet Silverado HD
Certain 2006-08 GMC Sierra HD
Equipped with Allison 1000 Transmission (RPO MW7); Duramax 6.6L Diesel V8 (RPOs LLY/LBZ/LMM - VIN 2/D/6) Engine
Located in Alaska and Minnesota; Canadian Yukon Territory, Northwest Territory, British Columbia, Alberta, Manitoba, Saskatchewan, Ontario, Quebec, and Newfoundland


THIS BULLETIN IS BEING REVISED TO EXTEND THE EXPIRATION DATE TO FEBRUARY 28, 2010. PLEASE DISCARD ALL COPIES OF BULLETIN 07293B, ISSUED MARCH 2008.
THIS RECALL IS IN EFFECT UNTIL FEBRUARY 28, 2010.
Condition

Certain 2006-08 Chevrolet Silverado HD and GMC Sierra HD model vehicles, equipped with Allison 1000 Transmission (RPO MW7); Duramax 6.6L Diesel V8 (RPO's LLY/LBZ/LMM - VIN 2/D/6), may have limited or no transmission fluid (oil) flow through the transmission oil cooler after sitting for an extended period of time, such as overnight, during extreme cold temperatures, less than -40 F or C, excluding wind chill. If the "Elevated Idle Mode", cabin heater performance option is operative and the engine is allowed to idle for an extended period of 15 to 30 minutes while cooler flow is limited, the transmission fluid may overheat, resulting in transmission damage, and subsequent failure. These low temperatures only occur in, and therefore this program only includes vehicles located in, Alaska, Yukon Territory, Northwest Territory and far northern or western plains areas of; Alberta, British Columbia, Minnesota, Manitoba, Newfoundland, Ontario, Quebec, and Saskatchewan.
Correction

Dealers are to reprogram the Transmission Control Module (TCM).

Once you get it fixed if it indeed requires fixing, have him Put Castrol TRANSYND in it....!!! DO NOT allow GM to refill the Allison with their proprietary DEX VI product or any other "synthetic" Trans Fluid they wanna soak ya for...its NFG for cold weather. Cannot stress that enough.

This issue came up in a massive way back in the winter of 05-06 in the Northern Alberta Oil Fields where literally hundreds of LBZ TQ Converters 's were blown...GM's DEX VI is only good to -35F....any colder and its literally GUM and will not flow.

Transynd (A Castrol Product - TES-295 Compliant), is what ALLISON themselves recommend. Good to I believe -60C. A Full Synthetic Transmission Fluid for severe service...IOW you can run it for 100.000 miles between dropping the pan.

In fact all you guys up there with Allison 1000's aught to be running this fluid....ya never know when the power goes out and you lose your heating pads right..??

I've been running that product since 07...
Swear by it...

Cheers,

Theo

Here's a perfect illustration of the utility of a TES-295 fluid (Allison tested and approved). And it's an issue that will not be preceded by evidence in a UOA. BTW, the same goes for a TES-295 fluid in high temperature situations — pulling slow and heavy in high ambient temperatures. While there may be other fluids that will do as well, these you can be sure are as good as it gets.
