    Morning,

    My daughter hit a tree limb in the road and the result was this hole in the transmission. The weird part is, there was no trans fluid on the ground and the car will still drive. I'm not very familiar with the driveline in this car. Anyone have any ideas? With a hole that size I expected to find a huge puddle underneath. Any ideas are appreciated.

    Chris

    It appears that it all leaked out quickly based on the size of the hole. How much further did she drive before she stopped? Once she stopped it may have already leaked all out. Did you look behind the vehicle for the distance she may have kept driving?

    She pulled right over. There was a trail small trail of drips about 50' and a even smaller puddle where the car stopped. I was expecting to see trans fluid covering the underside of the car and it's not even damp. I obviously need to put a trans in I just don't understand why the car still moves. Drop the fluid in any other trans and the car won't even go into gear. I'm just trying to understand the mechanics.

    Wow yes dry as a bone. What a tough transmission.

    Transmission must be replaced. Lost of used ones out there. easier to pull the engine/trans as a unit. Your looking at about $1500 to $2500
    installing a used trans.

    I would say the car is totaled especially if it has the original hybrid battery but don't know the mileage.

    Insurance company did total it but I bought it back from them. I have the capability of dropping the sub frame and swapping trans. I was just surprised that the car still drives. Time to get to work.
    Thanks everyone

    Basically, Toyota’s hybrid transaxles have only one gear train, and it’s always in mesh: shifting is done by controlling the gasoline engine and the two motor-generators inside the transaxle. This means there’s no need to use hydraulic pressure for power transmission or shifting; the fluid is only for lubrication and cooling.
    For this I highly recommend Toyota’s New Car Features books (more info) and training courses; I’ve also suggested some technical books for interested readers.
