Probably a small block 727. Check the casting numbers to be sure.

Don't bother looking for a vacuum modulator, Mopar didn't use them on Torqueflites.

Incorrectly adjusted throttle valve linkage will make it shift all over the place. On mild acceleration 1-2 shift should be at 14 mph. 2-3 shift should be at 28 mph.

You probably need a complete flush of the tranny fluid but before you do this an inspection is necessary. First I'd remove the pan and the shifter body and clean it thoroughly. Next, while the pans off, check the servo pistons to make sure the snap ring inside, that stops the piston movement, hasn't popped out allowing one of the pistons to drop down. If this happens, your band won't engage. Look for anything loose or out of place inside the transmission case. If your pressure control linkage is misadjusted, shifting will be erratic or nonexistent for some gears. Change the filter and fill the tranny after you complete the above, adjust the bands, and give it a go. If your not skilled enough or comfortable to service or rebuild components of a tranny, your last recourse is a transmission shop or a used tranny. I'd bite the bullet and go to a tranny shop - it may be something small that doesn't require a full rebuild, then again ........

Let's eliminate something simple first...

Are you checking the level correctly? Warm and idling in neutral?

Checking in park will give you the wrong level.

Grab a service manual from here if you don't have one already.
MyMopar - Mopar Forums & Information - Service Manuals

The trans section will show how to adjust the throttle linkage etc.

ok thank you all for the input right now my car is at my work and 1st week i n january it will be home ill drop the pan and report back thanks for a starting point merry christmas everyone

I wouldn't make dropping the pan the first thing you do. If it ends up being something external you may be able to avoid that pita all together.

Agree, don't take pan off until you get it working right then take it off and change fluid and adjust low/reverse band.
