it is a 1.6 auto gear box
hello to lose all the the even gears like this I'd suspect either a problem with the gear selector or the B shift solenoid inside the transmission on the main valve body I'd suggest to 1st check the shifter lever switch by removing all the trim around the lever and then checking the connection and wiring to the selector switch if this looks OK then disconnect the selector siwtch and use a meter to check that the continuity of the switch in each position if this checks out then the oil will have be drained form the transmission and the sump pan removed to access the valve body
