hi

when switching the od switch off the magna doesnt change back a gear like it should, goes in r and d find when you shift into those gears.

recently connected 2 wires to the od switch plug r/w to r/w and i r/b to r/y.

if i connect the r/b wire to the wire thats alive when the od switch is on and the r/w to the r/w on the auto ecu would that help

or will the transmission need new oil and service

when you turn od off was it in the od (4th gear)? Try accelerating to 80kph and drive steady for a while and then switch od off.

fixed it now

will a diamante transmission computer work in a 94 magna 3 litre, are they the same, does the diamante auto ecu have firmer shifts
