First you have to figgure out which part is the one causing the problem. Or you can replace them all and probably spend more that the $130 in parts.
The potential sources for the fault are in no particular order
switch (not too common)
wire from the switch (happens, and is a real bitch to change)
relay (common)
wire to the OD solonoid (could be bad where it rubs on the case of the trans)
wiring to relay (not too common, but has happened)
Remember in that $130 is not only the labor but also diagnostics.
