The throttle valve cable controls the transmission pressure. Adjusting this cable is the most important step when installing a 700R4 or 200R4 transmission.
The 700R4 is controlled by vacuum lines and throttle cable kick down linkage (TV) and need to be re calibrated to the engine as to being 4.3 or 5.0 to 5.7. Best thing to do is to get a transmission shop that knows how to custom install transmission like a speed shop.
The TV cable adjustment on the 700R4 needs to be perfect. TV cable is used to set part throttle shift points, line pressure and if not set right will burn up the clutch plates due to low line pressure.
Good luck and hope this helps. you going to need tools that most of us don't have, like to be able to measure and adjust the line pressure at different RPM. If you need more information, keep me posted and be glad to help.
try some transmedic .put a little in tranny .try to take out some fluid add it in dont over fill transmission .put about a half of bottle in it. it wiil loosen those stuck shift valves.
The float is probably mis-adjusted in the carburetor.
Either that or the choke is out of adjustment.
It would probably bne best to rebuild it if you can, or have it rebuilt.
If your vehicle has the 5.2 liter,aka 318 cubic inch engine,there is only one transmission model applicable and it is the 42 RE which used to be designated the A500.It is a 4speed overdrive transmission.If installing a rebuilt trans and new remanufactured dry torque convertor.You add 4 quarts initially,then fire the engine and add another 5-6 quarts for a total capacity of 9-10 quarts.Fluid level is checked with the trans in Neutral.If you are only dropping the pan,you will replace roughly 4 quarts.The transfer case fills separately,but uses the same automatic transmission fluid.Capacity for the transfer case is about 2 quarts/fill to the bottom of the fill plug hole.Good luck.
