it's easier to ask you chaps, rather than me trying to trawl through that friggin google.
any way a customer of mine replaced the batteries in his MITSI CHALLANGER. diesel 1996.
he recons ever since then he has had trouble with the auto hunting between top and overdrive, !do you think resetting the ecu could help ! !how do you reset these computers

Two thoughts -1) a spike has gone through into the gearbox computed because of the knackered batteries
2) with the batteries out the car has gone back to the default factory settings.

the trans ecu needs to be relearnt as has gone back to factory remove battery for 2 min then drive quietly for 30 min or so will also need gradual speed increases and open road

have you tried this n3d4sp3d, this isin't some bad dream your having !
this could be fraught with difficulties, but we'll give it a go !
ta chaps

He is semi correct early mitsi invecs (and mpi) learned adaption was stored in volatile memory. Disconnection of the battery for more then 16 seconds will erase learned data, there is however a correct drive procedure required to "relearn" the transmission

AH !ta savanna71
which is !1:you know, but you cant tell me.
2:you don't knowso you cant tell me,

TLD-I'm speaking from personal experience -the symptoms do sound like the computer has reset to default.The FIRST thing I've always been told to do is drive the vehicle normally and let the computer relearn your driving style/speed.
But has anything else about the vehicle been changed! wheel/tyre upgrade was my thought.bigger wheels changing the point the vehicle kicks into OD

this is diamante relearn but procedure is pretty much standard for most.
Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select
"D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle
shifts into top gear.
* Cruise at light to medium throttle.
* Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally.
* Process may be repeated as necessary.
