    Hey!

    Well at the point of a transaxle swap:

    What lead up to this:
    - Leaking Driver Side Transaxle seal
    - Drained the Transaxle Fluid and found water mixture inside (I've owned the prius for 2 years, never had issues)
    - Flush fluid out, add new fluid, Drove like normal.
    - 2 weeks later, hear a clunking kind of from the transaxle when put into drive
    - Go to flush the new fluid again to clean out the past fluid, to discovered it is mixed with water again.
    - Trying to find the source of water mixture, its NOT my radiator/antifreeze fluid from the engine or Inverter/transaxle (Someone mentioned I may have a cracked housing on the transaxle which is rare, but no where else the water would be coming from.
    - Picked up a trasnaxle for 100$

    Now, to change out I need some help/guidance.

    I've followed instructions gotten to the point where I've removed axles, everything around the transaxle and ready to lower.

    My question, for GEN 2 I saw they dropped the crossmember under the engine, DO I NEED TO DO THIS FOR GEN 3? Anybody that has done this swap please let me know. I don't want to drop it if I don't have to, but it is a tight fit to lower it out.

    Please HELP! I've done plenty of civic engine swaps but just changing the transaxle of the prius is a little of a pint to drop under right now.

    Thanks in advance for everybody's help!

    I’ve no experience, but anyhoo: think I’d disconnect and pull the engine, then the transaxle, all through the top.
