I am not fond of automotive computers.
My 1999 truck has a computer controlled automatic transmission, even though the shift lever is on the steering column. At 45 to 55 MPH it hunts between overdrive and third gear. The overdrive lockout does not work, so the only way to stop it if go faster than 55 or slower than 45. Annoying.
My PT Cruiser had a turn signal failure. Computer had to be replaced. $800
Then, a few years later, the ECU died. No new ones available. The shop got 4 "refurbished" units, all failed to load the programming. Finally, the 5th one worked, after being down all summer, $1800
The truck transfer case is mechanical shifter, as is the Jeep transfer case.. The Jeep transmission is a 6 speed manual, no computer.
Our 1966 Chevelle has no computer, except for the AM/FM radio. IMO, that's the way a vehicle should be built!
