B&M Shift Plus Revealed
Saturday, April 16, 2011 4:22 PM
As I have mentioned in another thread, there are only a couple ways that the Shift Plus unit can work. Considering how cheap it is, I was convinced that all they did was throw resistors in parallel with the Pressure Control Solenoid.....Behold







These are located side by side in the rectangular box portion of the unit. All we find in the "D" shaped portion is a crap load of epoxy around a basic 3-way switch.






So, just so you are aware of what you are buying: It's....
- one 10W 5ohm resistor
- one 10W 27ohm resistor
- one 3-way switch

...and the end result looks like this





I hope that clears everything up

cool! the only reason it sels is due to the name on it and the pretty packaging i guess

Let's not forget the ridiculously low price for an immediately obvious gain.

you you're saying it cost just a few dollars to build a shift plus lol

Just taking a guess, but from the toilet paper on your hand you must have cut yourself opening it lol

How hard was it to open? I may modify mine to have a dash switch rather than the annoying D block.

Paper towel, but yes, it was a rather painful experience. I have a few good slices on both hands from the razor blade and my knife. I had to pull out the hack saw just to get through the solid block of epoxy around the switch.

All you would need to do is cut the wiring between the D-block and rectangular resistor block, and then wire in a new switch. You probably wouldn't be able to reuse the switch from the B&M. Cutting through the epoxy, I mutilated one of the leads from the switch


I should make a correction though, it's not a 3-way switch. It's a SPDT on/off/on rocker switch. When you cut the wiring, you see three wires: white, red and black. The wiring looks like this








white wire = 5ohm lead
red wire = 27ohm lead
black wire = common (This is the same as the black wire at the end of the Shift Plus)

These were verified with my multimeter.

The one I opened was 5 Ohm and 25 Ohm.

Well now that we know exactly what it is and does, does raising the pressure like this help or the trans? I have heard raising the pressure can prolong the life, but others saying they were weary of raising pressure on old transmissions.

Ahh you suck, now I know the truth and the magic is all gone.

I wonder in the photo of the schematic, wish cable is the red and wish is the black, looking at the drawing, the upper is the black? wish is connected to light blue cable on the tranny? Thanks in advance TURBO
