Keep trying. Leave different subjects in your messages. He's old so confuse him! :roflmao:
I am going to post here and try not to ruffle too many feathers, I have a lot of respect for Mike L. I think you guys are battling high temps because the tranny fluid you are using could be much, MUCH better.
This same issue is being addressed and theories being tested in the oil cooling thread. Anyone want to take me on??? Use fluid designed to reduce heat under heavy loads and temps will be lower. Use what you are using and continue to see troubles. Just sayin...

Mike L. When you get the 6 speed coolers in, please pick out the best one and send it to mePlease PM me when they come in. I'll take one.
Oh no you don't.... I've been waiting. :rofl:
I myself am no expert and I do not desire to "take you on" unless it means a free trial with your product. I am always open to new ideas and products if the results are proven and others agree so you know your results are not fluke. Had great results with Amsoil and Transynd as others have as well. Your post seemed to point more of a finger than offering help on the topic. Judging by your sig I'm guessing your suggestion would be to run Schaffers lubricants? I have heard great things. Can you give us facts/info to help us learn about the superior products you strongly believe in? Are you a salesperson? (don't take offense I'm not being a wise ass)
Aftermarket cooler will drop temps as fluid passes throught it, but does nothing to prevent excessive wear where the heat originates.
Also, how much air goes through a cooler on a drag run, and how long does it take 20 quarts of fluid to pass through the cooler to begin with?
So to start with facts, lets start with what the external cooler does and when it completes a cycle. Then we will see about posting facts about fluids, not just Schaeffer's.
I brought these same questions up about oil cooling and the results are being compiled now. Oil DOES make a difference.

You typed a lot to completely avoid answering any questions. I'm not convinced oil can lower temps. Unless Schaeffers has reformulated their oil since 2008, I was not impressed with what I saw running their engine oil.
:smellslike:
So, EGGSACK (< The name this guy used to log in under), what are you trying to sell?

So......... Still waiting for your facts/info. Without getting chippy (I realize you just might have something valuable to say) so far all you have done is stir the pot. There are those reading this that feel the subject is important. You felt the same way so you posted. Were waiting for the info....... Discredit the cooler all you want but results you can take to the bank not claims, opinions, and stories. Again, prove your point and you will get customers. Till then you are just another guy posting his 02 on the internet.

The only signifcant way to lower temps is with a cooler, period. Fluids like TranSynd or its clones ( TES 295 ) have been known to drop temps by 5-10 deg, although I have never seen it. Synthetic fluids will lubricate better at high temps and protect the trans and also give you longer service intervals but won't drop temps much if at all.
The Allison has no problems circulating converter out fluid as it flows at 85 psi with spikes as high as 200 psi. I can double cooler flow with a slight modification to the pump and do this on my race transmissions.
Anyone running hot with the Allison will NOT drop any temps by changing to a different fluid. First you must find out what is making the trans run hot and address the problem. Converter, pump, suction filter ( not spin on ) and cooler flow. If you are seeing temps over 230 F a cooler won't help much as they only drop temps 20 deg and you are still at a unacceptable level. Switching to TranSynd at 230 won't drop temps but will protect the internals better at that temp.
I was a Schaeffers dealer and tried their fluids along with testing every other fluid out there. Not one of them dropped temps.

I've been doing the oil temp testing and have seen first hand in my truck that it lowered MY oil temps. I would have NEVER believed it unless I saw it with my own eyes and I had to check my oil adapter T-stat and my oil temp gauge to see if they were still working correctly. I'm running a Mike L. trans, cooler, and C3 oiler but it still has the garage door spring in the pump (not sure this helps cause the higher temps though) and it's always run in the higher temp range. It's been better as of late maybe because the motor is running cooler (less heat transfer :dontknow
. The Mike L. cooler is definitely needed on a built trans and most certainly will help a stock trans. I'm amazed at the results I've gotten so far (and the motor is smoother sounding on top of it) with the motor oil. I'm not trying to contradicting you Mike. This is only what I've seen and I want to get the Schaeffer 9000 in the 05 LLY to see what happens and to back up my finding on my 02 (which I plan to do this week). I'm at a loss for words in explaining why it has done this. It took 400-500miles to show up though. This is my engine oil temp finding only.
Let the poop storm begin.

I am not going to contribute to a poop storm with anyone. I am just going to share what I know about lubricants. And that is not that much...
But Transynd is only made as good as to get Allison out of its warranty period. That is just a fact of life. Allison wanted a great deal on a fluid that would more often then not get them out of paying for transmission warranty period and that is all. Same with any other OEM company out there. ALL OF THEM ARE IN THE PARTS BUSINESS. Does Allison make more money on selling GM, Peterbuilt, Freightliner, CAT, or any of them on the new transmission or the parts after warranty runs out. Um, PARTS!
Now all companies tell you that wear is normal. Really, Please explain to me what NORMAL wear is. Is it lubrication wear or is it real honest to god wear that CANNOT be prevented? Hmmm. Ponder that a moment.
Up until a month ago, I thought it was "NORMAL" for my LBZ to burn a quart of oil every 10,000 miles, and GM told me I was lucky, I had better than "NORMAL" loss of oil. Really? Since the second week of Feb, I have not lost any oil in my LBZ and I have 8,000 miles on this oil change. I also have the PCV reroute which I was told by Tony that oil loss would be "NORMAL" with the reroute. Hmmm, ponder that for a minute.
HEAT is caused in anything from FRICTION. Eliminate friction and there is an IMMEDIATE, SIGNIFICANT drop in temps. Some friction is needed in a transmission after all it does have things that lock up and use friction discs to control certain functions. The FLUID itself can also cause heat. A fluid traveling at a HIGH rate of SPEED also heats up, so beefing up a pumps flow rate in the same size holes, will also cause the TEMPS to rise. OMG, NO WAY, REALLY? YES, and I mean Significantly at that.
So to me, with my very limited knowledge of lubricants and anything else mechanical, this whole deal is be looked at re-actively instead if PRO actively. Preventing something from happening is WAY cheaper than reacting when something happens.
So then it comes to balance and effect. Just because a fluid is a "Synthetic" does not mean that it is the same as the "Synthetic" of another brand. There are differences in all of them. Some use the best stuff they can find, not many companies will do this, then others put what they need to get by, most fall here.
So since Schaeffer's was brought up, this company seeks out the best it can find and builds a fluid to help with the desired effect. If all the best base stocks and additives are comined in proper levels for the specific purpose, then a desired effect will happen. That is what really happens.
The transmission is a complex subject and in it, there can not be friction modifiers like in an engine oil. BUT, the highest quality base stocks will help reduce heat, improve performance and help get to the desired effect.
If you have a problem with heat, a cooler is the best way to reduce heat in fluid outside the transmission itself, I would also add that using a great fluid, also reduces heat and reduces wear inside the transmission so that cooler can work even better.
The stuff that comes in the bottle with the Allison name on it is a decent oil, but it is NOT the best out there. I ran it for 50,000 miles and then I switched to another brand, then I switched to Amsoil and they all were about the same. I just switched to Schaeffer's over the past 4 months, and I have seen and felt significant changes in what I feel in a transmission that now has 209,000 miles on it. The "normal" operating temps is now 10 degrees less than it was with Amsoil. I have not towed my camper with my truck yet. I will report what I find with an ALL stock tranny and a 10,000lb camper later when I get to it.

Yeh, but I am the first to speek up "outloud" and besides, if he anly gets one in, I'll sell you my old one cheep
haha, Good try bud :thumb:. Your wrong, but good try.
Thanks Dougsmith. Much better post. We've all spent thousands on an aftermarket transmission. It is important to take care of it IMO. All this info is great thanks guys. I don't feel like the conversation is personal or chippy. Carry on I'm learning/enjoying!
So you have proved you have limited knowledge of oil and you believe God makes Schaeffers, and TranSynd and Amsoil is so so. You have 209,000 miles on your trans and you credit 4 months of using your present fluid for this.
I know that, Michael, and I completely respect your results and opinion. I'm in no way doubting what you have found in your truck, but in my truck, I saw signs of extremely high oil temps while towing a small camper across Idaho in the summer and running Schaeffer 9000 5W40 synthetic oil. Unfortunately, this was before I had an oil temp gauge, but it is the reason I have one now. The day after that, I lost a piston. Coincidence? I don't think so. As you might understand, I'm a little hesitant to try it again.
