I hope you guys all had a good Christmas.
What the emjay controller is claiming sounds like pretty good stuff even to me. I mean it’s obvious I don’t know as much about transmissions as my Dad. when my Dad challenged emjay & ATS and Edward the $ 10,000 my mom went off on him. Both my Mom and I while we respect him and even though he is my dad we thought he was insane so I can imagine how you guys must feel with his stand on this issue. .
Most of you guys already know that my mom does the typing for my dad and before she would type the challenge he had to prove it to her. Basically how can controlling the governor circuit cause a bindup shift or pressure drop in 3rd gear.
Bill took us in my truck and used it as an example, he plugged in the trans x and we went for a road test. For the first 10 minutes of the road test the truck performed perfectly. I told Bill I wanted my truck to shift at 1900 rpms under moderate throttle and the truck did so with him controlling the transmission with the transex controller . There was no bindup or anything, it was good clean shifting. .
He was also controlling lockup and od, for the first 10 minutes the truck worked flawlessly. On the way back to the shop when the transmission went to make the shift into 3rd gear Bill made the rear end of the truck lockup. He also created a 40 psi pressure drop. He said obviously this was an exaggerated bindup shift to get our attention , he got that right quick, he also showed me bindup shifts that could only be detected by the pressure gauges. I will be straight up with you guys, the shifts felt good by the seat of the pants I could not tell it was a bind up shift until I looked at the pressure gauge. I spent a great deal of my growing up like most kids trying to prove how smart I was so after seeing this done in front my eyes I was pretty silent.
I drag race a lot with my truck , one of the emjay controller claims is that you can change your wide open shift points so that interests me. My truck is set up for me to shift at WOT at 3250 rpms and according to emjays literature I can change that to as low as 2600 rpms. Eventhough I don’t want to make mine shift that low it makes it sound like a guy could change his shift points under WOT with simple programming of the laptop.
My dad kind of laughed and said I should already know the answer to this one, he told me with the amount of company time I spend researching heads for our racecar this should be a no – brainer.
The governor solenoid can only flow so much oil. If your current governor set up can only generate 100 psi adding the controller is not going to change that to 120 psi, the only way it would help is if your governor solenoid can generate up to 100 psi and the pcm only allows 80 psi.
Only then can the controller help with WOT.
Obviously then I asked Bill how can I test the governor circuit before adding the controller to verify the controller will actually provide me with the earlier wide open shift points as advertised.
The procedure takes a professional transmission guys about ½ hour, it took me about 3 hours. I had to have a 0-150 psi pressure gauge. BECAUSE THE VEHICLE HAS TO BE IN THE DRIVE POSITION AND RUNNING AND SOMEONE HAS TO BE UNDERNEATH IT , YOU MUST MAKE SURE THE VEHICLE IS SECURE AND CANNOT FALL OFF THE JACK STANDS .
By installing the pressure gauge in the governor port I could actually see on the gauge what the maximum governor pressure would go to. I had to jack up the rear end of the truck . I disconnected the 8 pin wiring harness, at that point based on regulated line pressure the governor pressure was maxed out.
Then by moving the throttle lever the governor pressure would go even higher. That gave me my maximum governor pressure available in 1st gear, 2nd gear, and 3rd gear. . On top of that the boost valve circuit can also increase available governor pressure by an additional 10-15 psi depending on how much the boost valve circuit has been enhanced . That on paper gives you the maximum governor pressure available.
The next step was to plug back in the wiring harness and go for a road test and compare my wide open governor pressure with the pcm controlling the governor circuit. VS the unplugged wiring test I previously did.
If the 2 numbers match,the emjay controller cannot change your wide open shift points.
If the unplugged wiring harness test gave you a higher governor pressure reading then the controller will help with your wide open shift points.
Since no pressure testing data has been released, or no attempt has been made to tell you guys how to protect your transmissions using a pressure gauge especially since this transmission longevity is dependent on pressures, I thought perhaps this might give you guys some more insight as to DTT’s stand on this controller.
Considering Bill has over 2 years experience manipulating the governor circuit it just doesn’t make sense they don’t want him to test it.
I had Bill helping me through the testing, he would not let me use the hoist, I had to do it the way you guys would have to in the field. It took me 3 hours . Every one has the right to choose to do what they want, I just thought this might give you guys an idea as to how important the testing is, and that just because you can use a lap top does not mean its as easy as it is being made out to be. I can also use a laptop but the laptop does not tell me what is happening with the pressures inside the transmission and as I found out first hand seat of the pants does not tell you either. That is why with our smart controller you can adjust overdrive, your lock up speed , 2nd gear lock up , disengagement points of lockup system based on tps and vehicle speed with a simple screwdriver, but he will not allow you to control the governor circuit , we set that.
I went to transmission school on my holidays you guys, I wish you all a safe and happy holiday season.
Attention: TDR Forum Junkies 
I guess when the time comes, DTT will make another $50 off me. 
I got a SMART CONTROLLER
