Hello.
Let’s talk about Electronic Automatic Transmission control.
As far as complexity goes. Automatic Transmission Control is about as complex as most control systems can get.
Using the Wolf V500 you can use a combination of MultiControllers and General Purpose Outputs to control a multitude of different types of transmissions. And you are going to need a lot of these control systems, as some electronically controlled transmission require 10 inputs and outputs (just connected to the transmission) to control shift points and shift hardness, etc.
Auxiliary Inputs can be used to sense where the gear selector position is. Some transmissions use only 1 wire for this, where others use up to 3 or 4 wires just to sense the selector position.
Auxiliary Outputs on the Wolf V500 can be switched or pulse width modulated to control which gear the transmission selects as well as line pressure and torque converter lockup.
It’s lucky the V500 has many auxiliary pins.
If we tried to explain the way the V500 controls the transmission in this email, it would appear very complex, and some people may be confused or even put off by this. But there is nothing to worry about in that regard. If you buy a Wolf plugin ECU that controls the automatic transmission in your car, your Wolf dealer will be able to help you tune the shift points to where you like them. Or, you may be happy with them from the start. We try to make the transmission shift almost like standard at very low throttle openings, and get harder as the throttle is opened, until it is a little more firm than standard at full throttle.
Once it is setup, it is relatively easy to change shift points and line pressure.
That being said, we currently only support that automatic transmission control is adjusted by selected Wolf Dealers, as it could be easy for someone to get themselves a little tangled up with this.
If you have a transmission in mind that you would like to control, drop us a line at wolfemail@wolfems.com.au

I want to use a Wolf V500 to control a GM transmission T4L80E. IS this Possible any help would be appreciated
Hi Ricky, We do use the V500 to control GM Transmissions, and in this case, we can control your box.
Can you set up a millisecond “power cut” on up-shifts, with the V500??
There isn’t currently a full throttle upshift available at the moment, although you can use the MultiControllers to set up an ignition retard under the conditions you require for the upshifts. If you want to talk more about this, you can email Robbie McQueen at robbie@wolfems.com.au. He’ll be able to give you all of the information you need about this and anything else you need to know about the V500 and tuning, etc.
