    Well, well, well....why am I not surprised?? After a complete engine remove and re-build, auto transmission now will not engage gear!! I know the Zed is known for it's recalcitrant ways, but this is getting ridiculous!! Removed transmission pan and replaced gasket after minor leaks (?) but car still won't engage forward gears. Car will reverse but no forward motion....
    After this does anyone know what the next Zed 'trick/s' is likely to be? Just thought I'd start to get prepared for it's next little "try this on for size" stunt...!!
    In the meantime, any thoughts as to why no-go....??

    You said auto. Check fluid very carefully

    Yeah, thanks Madcow....researched and surprised at fluid level required (7.7lt) but correct quantity was replaced. Just no forward engagement of gears nor movement of car....????

    SYMPTOM(S): Transmission Has No Forward Gears ? Reverse Gear May Work
    CAUSE(S): Problem with Valve Body or Other Internal Problem Causing Pressure Loss
    RECOMMENDED ACTION: Diagnose Problem and Repair
    ESTIMATED DIAGNOSTIC COST: Repair Shop: $75 to $125 DIY Cost: $0
    ESTIMATED COST: Replace Valve Body: Repair Shop: $375 to $1000+ DIY Cost: $250 to $1000+
    ESTIMATED COST: Rebuild Transmission: Repair Shop: $1600 to $3500+ DIY Cost: $400 to $700

    NOTE: Diagnosing a valve body problem typically requires a transmission scan be performed at a repair facility.
    Most repair facilities will waive diagnostic charges when the shop makes the repair.

    Try to do a manual diagnostic on the auto tranny. There is a write up on here somewhere explaining how to do it, by turning key on and off, changing gears and then reading/counting the flashes of the engine light.
    might help :)

    possibly...check that the o ring on the filter is seated correct...also the filter is sitting flush and hasn't dropped during gasket replacement.

    Nothing, guys...thanks anyway. Car will actually move in reverse, but won't select any forward gears. Transmission worked OK before previous drama with engine timing and engine rebuild. Now engine works fine but no gearbox motion....

    Have you checked the fluid level on the dipstick with the gearbox in park and the engine running?

    Did you remove gearbox when you did the rebuild.
