Re: Transtim PCB

can I assume these sensors generally on/in the trans itself? zeroRYE, Yes, the sensors are in the trans itself, in something called the pressure switch manifold (PSM). You connect the GPIO board to the main connector on the 4L60e, and the shifter position is fed out on pins N, R, and P (aka. switch...

Re: Transtim PCB

zeroRYE, As long as the shifter uses 3 digital inputs to signal the shift lever position, use the GM build. If you need more than 3 digital inputs, or if your shifter will put out a varying voltage signal to indicate the shift lever position ( http://www.msgpio.com/manuals/mshift/voltlever.html ), t...

Re: Transtim PCB

zRye, Does it look like this one? http://www.msgpio.com/manuals/mshift/transstim_built.jpg If so, it is probably the correct switch (I have used this switch several times on my trans stim builds). Note that the instruction manual ( http://www.msgpio.com/manuals/mshift/v2transtimbuild.html ) says: 22...

Re: AA80E 8-speed

Jim,

The upshift paddle is most likely a code problem. I will look at it as soon as I get a chance (we have visitors from the other side of the continent at the moment).

Re: AA80E 8-speed

Could this dialog be advisory? I note is says, "With standard build." Jim, Yes, this page doesn't have any actual settings at all, it is purely there for users (mostly me!) to have a quick text reference to the pins, circuits, and amp pinout when trying to figure out things like which spa...

Re: AA80E 8-speed

Jim, That sounds right to me. The first thing you might do if you aren't sure about the inputs is to use the new input test mode ( http://www.msgpio.com/manuals/mshift/V5tune.html#ot ) to check if the code is responding appropriately to the lever inputs. I couldn't recall off the top of my head if t...

Re: AA80E 8-speed

Jim, I'm somewhat concerned that it does not change when the shifter is moved As I said above, the display does not show the manual gear lever (i.e. shifter) position. It displays the current gear position (which is only in effect when the engine is running, etc.) I didn't see how to expand that to ...

Re: AA80E 8-speed

It is the numerical gear indicator. It should be showing 0 for Park/Neutral, 9 for Reverse, and gears 1-8. It reads 0 in all positions. Jim, Is the readout this one: http://www.msgpio.com/manuals/mshift/7segment.html and driven by the LED outputs? If not, what sort of setup is it? If it is the 7 se...

Re: Damage from no recirculation diode?

bigwheels6, My condolences on the brain injury - they aren't a lot of fun. I will have a look at the datalog and msq when I get a chance. If the lacquer is still in good shape, then you probably don't need to clean the board again, but if the lacquer is cracked or peeling anywhere, I would definitel...

Re: AA80E 8-speed

DRO doesn't change when I move the shifter between PRND. Should it?
Jim,

Possibly, what is a DRO?
