Title: Gearbox ECU
Post by Scorp_Kev on Jan 13^th, 2012, 11:13am

Hi. Could anyone tell me if the auto box on the 2.3 ultima has a seperate ECU and is it easy to change. A last resort to try and solve my ongoing gearbox problem. Thanks

Sorry remind me of the 'gearbox problem' ?

I did a search on 'last posts' but kept getting Gateway Timeout ::)

When cold, if I select reverse, it puts gearbox in "limp" mode. Its fine when warm. I have an odb2 reader to clear codes, that seems to take out of limp mode.

Ah yes thanks.

Have you done the others' suggestions in that topic? E.g. Dave2302, he's our autobox guru. ;D

PS: he's right about warming it up then turning it off, then restarting, turning it off takes it out of limp mode.

PPS: the Scorpio's ECU is aka PCM (Powertrain Control Module) so-called because it also controls gear changing via solenoid valves, it also electrically tests all these electrical bits. 'limp mode' is invoked in the event of a problem, in order to prevent further damage to the box. So says owners handbook anyway.

I highly suspect changing the ECU module won't make any difference, but might be worth checking its connectors though in case there's an electrical connection issue. (?)
