Transmission Question
I have a 94 3.0 and I was wondering if anyone can explain to me why everytime I shift from park to drive or from park to reverse it shifts into gear pretty hard. But once I'm driving the gears shift fine and without problems. Any idea's?

mine has always done the same thing. if your idle is alittle fast when its cold will cause this to be worse. some of this i think is the nature of the beast. in other words welcome to ford.
also i did change the ATF and it seemed to help.

Lots of things can cause a hard "thunk" when shifting from idle. Lasher is correct, a fast idle when the engine is cold can elicit this. Low transmission fluid levels will cause it as will sticking hydraulic valves, worn/mis-adjusted bands and/or excessive play in the driveline from worn splines on the output shaft or u-joints. Exactly what is causing your condition would be hard to say.
If you want to try a 'cure', the best place to start would be to check the fluid level and also have the transmission fluid changed if it has not been done in the last 60,000 miles or so.
Here is a good link about how transmissions work. http://auto.howstuffworks.com/automa...nsmission2.htm

Thanks for the suggestions. I have transmission fluid leaking into my transmission vacuum tree coming from the transmission modulator. I'm not even sure what the modulator does, but with this modulator being bad is there any chance of this being the cause.

Modulator "modulates" the shifts - makes them smoother under varying conditions. Need to replace that modulator before anything else. You will likely be low of transmission fluid because it has been going into the manifold and out the exhaust.

My car does exactly the same thing. I think it is probably worn mounts.
If you put your foot on the brake and shift to "D," Does it clunk?
If it does, have a buddy shift to D and observe the engine and transmission. If it shakes then it probably is the mounts.
