  1. Hello Jack,


    Steven Harris should know and old stand by for smoke jumper resupply parachute is a good old fashioned GI Poncho.

    Thanks for all you do.

    Blessings to you and Yours.



  2. Jack, thank you for addressing Gary’s comments.  It’s been several years since he answered a question about keto and his information was dead wrong.  I would imagine that he comes from a different place in his health journey, and that’s fine, but sharing bad information when people view you as an expert is dangerous!

    When I get to my goal weight, I probably won’t change my eating any.  Not only does keto control my diabetes, but it controls inflammation and other auto-immune disorders along with being neuro-protective.  Why would I choose a banana when I can have a whole cup of raspberries for many fewer carbs? Why would I wreck feeling fantastic just because I see a certain number on the scale? I know a LOT of folks who are at their goal weight but use keto to control their other health conditions.  It’s a thing! 🙂

    Thanks again for the great suggestions about how to eat keto on the road.  That’s exactly how I do it.  Or if I’m in a terrible pinch, I’ll order burgers with no buns wrapped in lettuce with all the other veg.  It works!

  3. Hello Jack,

    The information regarding how to connect an auxiliary in-line transmission cooler seems to be incorrect.  The expert recommended having the stock in-tank (radiator) transmission cooler being last in line.  This seems really counter intuitive.  The auxiliary cooler could cool the transmission fluid to below radiator temperature, and then the radiator re-heats the fluid.  This would limit the effectiveness of the auxiliary cooler to reduce the temperature in an overheated transmission – which would likely occur in conjunction with an overheating radiator condition.

    I have several GM trucks which have factory towing packages and thus have two coolers – the in-tank cooler and a factory auxiliary cooler.  Every one of them has the transmission fluid route through the in-tank cooler before the factory auxiliary cooler.  Furthermore, I also checked the installation instructions for the popular B&M add-on transmission coolers, they also state to put them in-line after the in-tank cooler.

    I totally get the expert’s thinking that you don’t want the transmission to get too cold by adding too many transmission coolers.  I believe this comes back to knowing the vehicle’s application and usage parameters.  If the vehicle is towing across the Rockies in August, absolutely keep it as cool as possible.  The same vehicle without a trailer, in Minnesota in January will be too cool.  But again, knowing the vehicle, simply tape some cardboard over the extra coolers during winter and let the transmission warm up.

    A side note confirming the expert’s advice on regular transmission service…  My daily driver has 308k miles on the original motor & 700R4 transmission, neither having been rebuilt.  I drop the transmission pan, change the filter, and refill every 15k miles.  Some may say that is too often.  But for me it is money well spent against an unexpected transmission rebuild and the associated breakdown miles away from home.

  4. Hey Eric

    I should have approached this one with a “it depends” instead. I guess it just depends on the vehicle and how good the factory cooling system is. If the vehicle is known for running hot with an undersized radiator that is being worked hard, potentially the engine could be pushing excess heat into the trans cooler. But, if you are running your engine around 230 plus degrees you are getting into the danger zone anyway and both engine and trans are doing bad at that point.

    Maybe I am biased being up north in that if you run the aux cooler last you can drop the temp too far and that some modern vehicles may not like that affecting shift quality. They want to be at a spot on temp. A lot of new vehicles have thermostatically controlled cooling loops now.

    I think the best way is to just get rid of the radiator cooling loop all together. This gives you complete isolation from one another so engine and trans do not affect each other. You also don’t risk damaging the trans if the radiator corrodes and dumps coolant into the ATF. A thermostatically controlled cooler by itself with its own fan is far superior to any stock setup.

    308k miles on a 700r4 never being rebuilt is incredible, especially if it is an early 80’s vintage.

  5. On wiring, if this is an occasional use cabin, I would take Shawn’s advice a step further.  Steel clad wire isn’t that much more expensive than regular romex, especially when you consider the increased security in it’s resistance to rodents.  Also pay the extra for rock wool over fiberglass insulation as rodents won’t chew the rock wool.
