I just removed the kickdown valve and solenoid on two cars, both 87 300TDT's.
Once removed the fluid came gushing out.
Definitely not a few drops.
On the second one, I put a plug in asap and when I replaced the unit and refilled the tranny it took at least 1/2 to 2/3 of a liter.
Be warned you need to be prepared for a lot of fluid.
