TSB 20-2190 DIY

[w102acd]

 

We recently bought a 2019 Ford Edge ST from my in laws.  I was expecting it to have the 8F35 tranny, but it has the 8F57.

 

It was having shifting issues (maybe 4-5 with some "flaring").  My in laws weren't sure when the tranny fluid was changed so did that (and it didn't look too bad).  I also reset the adaptive tables in FORScan and this made a huge difference!

 

My question:

In TSB 20-2190, it says "Reprogram the PCM using the latest software...".  Is this different than resetting the adaptive tables?

 

If it is different, is there a way for me to see if this has been done?  I have a laptop, cable, and FORScan extended license.

 

If it hasn't been done, is this something I can do with FORScan?

 

Since it's good after the adaptive table reset, should I bother with this TSB?

 

Thanks!

Yes, you need to update the firmware of the module.

ForScan can flash the PCM firmware. But you will need a paid license, a very good wired adapter, and to know which Firmware versions are required.

Also, you should be using a battery charger/maintainer (minimum 10 amps) to keep a stable voltage during programing. If the battery voltage drops too low, the firmware update can fail.
