430 Smart eMT F1 Relay "normal operation"

I haven’t driven mine in a while, but I’m pretty sure it wasn’t operating that often. The relay has some diagnostics associated with it, are they giving you any warning? Are you losing fluid?

I’m no expert, but sounds like the system is losing pressure, with all the accumulator/actuator/bleed activity, personally I’d start at the beginning and give the entire system a once over, change the F1 fluid and start the bleed all over again.

 

The x431 has the capability to do real time graphing of pressures .. try doing that while idling , driving straight and in circles and then look at graphs ... Someone did tfaf on here and it definitely helped track the problem down

My initial experiences with the smart relay in an '06 430 with comparable mileage were similar to yours. No problems with shifting, so I just got used to ignoring the alerts from the smart module. Then a little more than a year ago, I went to upshift from 1st gear after a long cruise and no response from the paddle input for about 5 seconds then back to normal. This would happen very occasionally at first, but of course became progressively worse over time while our indie and I tried various remedies to eliminate the problem (i.e. bleeding system, ediff solenoid replacement, new accumulator). The module also started reporting more second-level alarms where the red flashing light stays on in the module until you clear the alert (or turn off the ignition).

Long story short, 2 of the F1 actuator bleed screws turned out to be loose, which appears to be a fairly common problem with the 430s. Alerts from the smart module dropped significantly after reseating the loose screws. I still very occasionally hear an alert from the smart module, but nothing resulting in a second-level alarm that had to be cleared from the module.
