ok, I found the stuff from my shift kit and it has a resistor in it (don't know what size) but the instructions said if you use an aftermarket programmer don't use the resistor. so should I still use it or not
Just about everybody that uses resistors have a programmer :D

I ran mine with superchips and now sct with no problems. Get the 1.5, you will feel a difference between the two.
 
Cant give you a super long explanation due to time but it basically shorts out the sensor fooling th computer into thinking there is less line pressure then there really is. The lower the resistance to ground the more line pressure.
 
You're not seeing it like I am...

If you go from stock with no resistor and it makes (example) 100psi of line pressure, then add a 2.2ohm resistor and it now makes 120psi, how can adding a LOWER 1.5ohm resistor make 130psi?

See? I understand how a resistor tricks the TCM into upping the pressure, I just don't understand how going to a LOWER resistance makes MORE pressure.

Wish I could still see my Transgo resistor to decode the bars on the side and see what ohm it really is.
 
Perhaps that particular wire reports back to the PCM what the actual pressure is and if you add a resistance the PCM reads that its lower then programed so the PCM sends more volts to increase the pressure until it receives the correct reading. So with resistance the PCM must increase the line pressure voltage to read what ever its programed to be even with the resistor in place.

What are you guys smoking?

Let me put it another way. Let's think of the resistors as a restriction in a pipe, ok?

Hypothetical situation:

The pipe is 2.5" diameter, which flows 100gpm @ 100psi. Now lets compare restrictions, 2.2ohm will be a 2" diameter restriction and 1.5ohm will be a 2.25" restriction (note: the larger ohm matched with smaller pipe because more ohms means more resistance)

The pipe with a 2.25" (1.5ohm) diameter restriction will flow the same 100gpm at say 110psi.

The pipe with a 2" (2.2ohm, more restriction, more ohms) restriction will flow the same 100phm at say 125psi.

Get it now?

I think you need to let off the pipe yourself...LOL JK... You clearly did not even attempt to read and understand what I posted.

Your ASSUMING that the resistor is inline with the line pressure voltage and has a DIRECT effect on the line pressure by controlling line pressure voltage.

BUT

I think its NOT in that line at all. I think its in line with the sensor that only READS the actual line pressure. And altering that signal to read LOWER will cause the PCM to raise the actual line pressures.

Lets just throw BS numbers out there to make some since of it.

If the line pressure is 100 lbs and the PCM is set to look for 100 LBS then everything is NORMAL.

If we attempt to add resistance INLINE with the wires that control that vlotage then YES your absolutly correct... it will have an opposite effect and line pressure would be decreased.

BUT lets just ASSUME that the PCM has another sensor reporting back the actual line pressures... Separate from the wires that actually control the line pressure. More like a check and balance.

If you alter what the PCM see's you can indirectly alter the line pressure just by altering the "Reporting" signal that the line pressures are too low... so the PCM will increase the voltage to the un altered wires that actually deal with the line pressures.

Kinda like two people doing a job... neither one can see the other but they can HEAR each other... One is controlling a crane lowering 15 tons of crap (A-MAN)... the other is verbally REPORTING clearances and speed. (B-MAN).

Now the (B-MAN) confirming the clearances can not really have a direct effect on how fast the crane moves... but him reporting the lift operator to SLOW DOWN will indirectly cause the lift to SLOW DOWN.

Now applying your idea to this would be like the (B-man) sitting in the same seat as the (A-MAN) trying to control the crane' speed... thats just not going to work.

So by placing the resistor in the sensor that REPORTS line pressure will cause the PCM to receive a false reading. The PCM will then RAISE the actual line pressure voltage until it receives the correct reading.

Hows that for a crack smoker?:wave: JK...

Im just trying to point out that it is not in line with the wires that carry the ACTUAL line pressure voltage. Its most likely in line with the wire that REPORTS actual line pressure. <--- Im just assuming just like yourself... so I could very well be wrong... but it sounds plausible to me.
