automatic gearbox not changing gears??
hi i have a year 2000 suzuki jimny and it has a auto gearbox.
My problem started randomly before was working fine, the gearbox does not upshift or down shift.
when i start the car to go and drive in D it will go straight to gear two or three very hard to get accelerating then it wont shift gears up or down when accelerator is floored.
also if i start the car and immediatly hit gear one it the vehicle starts to move in gearone then it will upshift very harsh into gear two, and wont go to gear three or down shift again.
Also changing the gears manualy have no effect while driving slow or fast hit 2nd or first and it wont down shift.
im thinking its an ecu problem as the gearbox was working fine a few days ago with no slip.
i checked all wiring even under the gearbox.
could the ecu be in limp mode? There is no check engine light on.
