Why wont the pms work

I am at my wits end with this gpio. I get 5 volts out to the appropriate ports and down to the pressure manifold switch but, and if i ground the wire inside the connector to the pressure manifold switch it changes state, on my outputs. Reading the emperature works correctly etc, i just cant seem to get the gpio to recognize what gear i am in if any all of the inputs act as if nothing is connecting anywhere. Is my gpio messed up becouse i only output 5 volts to the input 1 (pin 26) input 2 (pin 6) input 3 (pin 25) . Any ideas here guys please help me. The donor vehicle ran fine with this trans and stock ecu btw and i installed a brand new pressure manifold switch when i first realized this problem was happening.

m-5m,

What transmission are you working with? Could you post an MSQ and a datalog of the problem?

A log of you shifting the lever through the gears would be helpful, it will show what the controller is, or isn't, getting for signals. Lance.
