    So I did a conversion on my 87 motor and redid the c4 trans with a stage 2 kit, new tourque converter and a megashifter. Everything seems to be hooked up right and added about 7 quarts of type F fluid.

    Started up the motor and put in gear and nothing, seams to feel like neutral in gears except PARK.

    What's up with this problem?

    If it was dry you still got more fluid to add it'll hold almost a whole case

    Okay, the guy who rebuilt my trans told me about 8 quarts. So if it's not fully filled, it won't move? Cause I'm not familiar, I'm new new to this and learning as I go.

    Befor I got the motor running, the carb was spitting out gas thru the top and a mechanic told me to bring it in and rebuild it. I just figured it was the timing, so I advanced it and it started up.

    Need to check trans fluid with it running I do believe you will find it low , as far as the carb sounds like it either has bad needle seats, too much fuel pressure, or dirt in the needle seat

    First, I have to say the 95% of all issues with a new trans are either;

    Fluid level..............if you have put 7qts in before your started, well you have enough fuild.............assuming you have a standard pan or do you have a deep pan?

    Incorrect linkage assembly.................have you double checked you installation..........remember P then R then N then 2nd then 1st...meaning that Park would be closest to the front of the motor and every position after that is toward the rear of the transmission.........when you shift the transmission from underneath at the transmission selector attached to the transmission on the side.

    Missmatched parts or not installed correctly. Did you have the transmission rebuilt by someone, who is the company. When you put the converter in, did you spin it to seat it, did you bolt the converter to the flex plate? If you did all of the above correctly I would be on the phone and ask them.

    On a brand new transmission, you should jack the car up so that the rear tires are about 3 to 4 inches above the ground, pour 4 quarts of fluid in the trans, start the motor.............put it into gear and start adding fluid until you put in 6 to 7 quarts..............now run the trans through the gears then check the fluid level and add...........maybe another quart or maybe less than a quart....................run it through the gears again, check the fluid level and if everything is ok, put it on the ground and................then check for leaks.

    Did you hook up the vacuum modulator??????????? If you did, I would check the linkage like I mentioned above. Let us know.

    IMHO

    I put a new converter in empty, when it's running, it looks enough but with the engine cooled, it looks dry. I'll keep adding, thanks joe

    When i jack the car up, the motor isn't on,right? I'll double check with the vacuum. The links are fine, car stays when it's shifted on park.

    alright, guys. so i added 2 more quarts and the car started to move. good sign. it had a slow response, but atleast it moves on drive and reverse. i added an extra quart, so all i have to do now is add exhaust so that i can tune the vehicle. thanks everyone for your quick response

    One thing to remember..................only take the dip stick from the transmission when it is running..................you have to have the pump working in the trans.............and that only happens when the motor is running.
    How many quarts did you put in the transmission? Do you have a deep aluminum oil pan on the trans?

    OK, you really need to check the fluid again with the motor running and in Park. Just make sure it is on level ground.
    Just as a reference; the C4 that came behind a 302 takes 9qts and no more unless you have a deep pan; the C4 that came behind a 351 takes 10.25qts and no more unless you have a deep pan. A C6 does take 12qts and of course the AOD's take almost as much as the C6.
    If you start the motor and check dip stick, wipe it off and stick it in again, and if you can't tell where the level is or tranmission fluid is all over the stick..................shut the motor down...........drain a quart of fluid and try again...................too much fluid will kill a transmission.
    Next time if you ever put a new converter in...........put about 1/2 quart in, don't put it in dry.

    okay, now the trans is getting a better response, but the engine wont stay fired up when i let go of the gas.

    i forgot to meantion that i have two different types of exhaust. driver side has a smaller type from the original 73 motor, and the passenger side has a bigger exhaust, thinking from an 87 motor.

    reason i did this is because i first installed the passenger side and it cleared, then TRIED to install the driver side and it was hitting the motor mounts and wouldnt bolt on flush on the motor. so then, i installed the smaller one.

    what can this exhaust combination result in?
