    well 302 is in. no exhaust yet no floor linkage yet. just a hole where it is gonna go. the craziest thing. (shift arm on tranny is switched to the floor shifting position or 180 degrees from normal) todd says all positions aside from PARK make the car go forward! before i go nuts troubleshooting, is this possible? how? there is the right amount of type F in there too.
    thanks

    Scott when ya'll drobed the valve body to flip the linkage ya miss stabbed the manual valve........I hate to tell ya this but ya gotta do it again:( (manual valve= the part of the valve body where the pin on the shift linkage makes contact with the valve body) the linkage needs to be between the 2 discs on the manual valve...

    OOOOOO ok, now i know exactly what you're talking about. That pin in the corner by the vac. mod. It has to go in between the peices in that slot. ok ok now i know, I was wondering if it mattered when i did it and forgot about it. Man do i feel stupid. Inexperience = inexperienced mistakes i guess.

    so now all you have is forward and neutral??? will it not go in reverse or park???? if this is the case unhook the linkage from the tranny to the shifter and see how many shift points you have on the linkage (clicks) if you have 5 clicks with the shifter un hooked put the tranny linkage where park should be on the tranny and see if it goes into park(make sure no roll) and from there see if you can put the tranny in reverse from the tranny linkage..........maybe your linkage needs adjusted.....

    Before you go tearing it apart again, have you "bled" the transmission? Starting with an empty pan, you'll add four quarts or so. Start the engine. Then, get in the car and shift slowly...P, R, N, D, 2, 1, staying in each gear about 5 seconds. Then go back through them slowly, and leave it in park. Now, get out and add another quart (or two). Do this again....P, R, N, D, ....same as before. Then get out and add another quart. Keep doing this until it goes into all gears, then get the level topped off. You will need to check the level again after a day of driving. The total is usually 9 or 10 quarts.
    The torque converter is probably not completely filled with fluid and there is still probably air in the valve body and servos. You just need to slowly work some fluid in there. It will not go into gear until you get rid of all this air.

    Good luck!

    Thank you a whole lot!!!:):):)

    We have "bled" the trans, I get all the clicks, all the gears, now it just wont upshift. Tomarrow i am going to check all my connections on the vacuum lines and the vac. modulater. I am sure it is now just a matter of faulty vacuum connections etc. When i turned over the shift lever on the trans to accept the floor shifter i put it in the wrong slot so i dropped the valve body again and realigned it and now we get all the gears. it just wont upshift so i am pretty sure its a vacuum prob. thank you all for the help. Hopefully it should be working good by tomarrow if not tuesday night! thank you again.
