Ok, so one day while car shopping, looking for something good on gas. I find my beautiful 73 mustang. She was perfect for about 5 years then blah one day no drive. So I love a challenge and convinced my dad (who is a wonderful shade tree mechanic with no transmission rebuild experience and a daughter who says we can do it) to rebuild it. So we take everything off the transmission and drop it, take it out, rebuild it and we are ever so confident.Everything just fit perfect together. We put it back in and filled with fluid. So we expect everything to work we taken off then put everything back just the same. So why when I go to start her up does she turn on her pretty dash lights but nothing happens? NOTHING...Anything would help at this moment. I'm thinkingthat it has something to do with being in park. I dont think it is in park.How do I put it in park?The car rolls freely. even though we took the shift linkage off and put it on the same way we took it off. Am I missing something here. I know I'm not the best mechanic. So it's a possibility. HELP PLEASE

The fact that you've got slipping in reverse and first at least will narrow the problem down. The C4 shares the "low band" for reverse and 1 on your selector. There's a reverse "band" that's tied into a hydraulic solenoid that will stop the outer band from turning and engage the inner ring causing the output shaft to spin in reverse. Sometimes if you've got to low of a fluid level there's not enough to push that servo all the way and lock into reverse but since you're not finding 1 nicely either I'll say its mostly one of two things. 1) you've got too much fluid. This can cause some slipping issues or 2) you put the valve body back together incorrectly.If you've got no transmission experience and its problem 2, check and double check that all your balls are seated in the correct spots. This is of course assuming that you didn't take apart all the valves and internals to the VB. Otherwise you might be best off either taking the VB to a professional or to buy another one. Seriously, Automatic transmissions are not fun to tangle with. It'll take you lots of spent time and $$ to get it right.
The simplest thing to make sure is that you've got all your clutch packs seated correctly, the servo's are free to move without stiction and that the little balls inside the VB are in their correct spots. Just by moving those from one spot to another can make a transmission work or not work.
To add to it if you're not finding "park" and the car is moving freely then you've got some other issues as well. If you can put the transmission in park by moving the lever on the transmission by hand, then you've most certainly got something wrong in your linkage. Otherwise you most definitely put something together wrong.
