Hi everyone , I’ve just got a smart 451 and gear change was working but a bit sluggish so I came across a post on here and stripped and cleaned the actuator I then decided at the same time to strip and clean the gear motors and change the gearbox oil , when I got it all back together and turned ignition on there was a lot of noise etc while it was checking the gears , then when it finished the car would not start , I tried the learn mode with ignition on , it goes into reverse, neutral, 1 and 2 and back but will not go into 3 4 or 5 , the car will start after this but not move, it won’t go into any gear when running, once I turn it off I have to repeat the process to get it to start again but it’s always the same :(
Gutted
Any ideas please

i have also read that there is marks on the cogs on the shift motor to align up when refitting but other posts say there is nothing to align up so i am a bit confused , i dont really want to take it all back to bits if there is no marks to align

i noticed on this picture of the gear motor you can see a triangle mark, so would the gears in the tranny have the same mark to line up with these ?

Yes both motors are moving when tested out the gearbox , engine light was on but it’s off now I think it was because of having it running with no air pipes on , I don’t have diagnostic software :(
