    First things first. Check the color and smell of the fluid- brown and burnt smell= heat problems which are usually signs of old age, burnt clutches etc. Check the vacuum line to the modulator, if it's got one, and replace it if there's any question. Then the linkage and kickdown cable adjustments to be made. If thats all good, you will need to tear the tranny down to find out what's wrong inside.

    You won't move, constantly burning tranny fluid. Lots of metal shavings in pan. If fluid is burnt try changing fluid and filter. See if it helps any. Always check fluid level first with engine running.

    Sorry to tell ya, Confederate9, but I think I hear taps playing in the distance for your tranny. From what ya said before that tranny is definitely DOA.

    There are only three things that warrant pulling the transmission out of the vehicle:
    -Burnt clutch
    -Fried Band
    -Exploded part

    The last one means that you have to do more than just replace the blown-up part, you have to clean the metal out of every part of the transmission.

    If one of the first three conditions doesn't apply, there are many things that can be done while the slushbox resides in it's normal home.
    -Clean, rebuild, replace seal for governor
    -Clean, rebuild, replace seal for Servo
    -Clean, rebuild Modulator
    -Check TV linkage
    -Air check the operation of the servo
    -Remove and clean or rebuild the entire valve body
    -and of course, change filter and some of the fluid.

    As said before, fluid level is very important. Always make sure that it is right according to instructions (i.e. warmed up, engine idling in drive against the parking brake). Whether or not the level was correct last week or even yesterday is irrelevant.

    It has to be in drive to check it???? I thought it was to be warmed up and in park, running.

    You ahve to have it warm, but you need to shift into each gear all the way to first, then back to park through each gear, THEN measure. You HAVE to make sure the fluid is hot thoguh first...just letting it idle for a few minutes won't do it IMO...the tranny will be overfull if you don't get the fluid nice and hot first.
