92 thunderbird transmission slipping, its about a half of a quart low. would this cause it to slip and what type of fluid do you use?

Why Is My Automatic Transmission Slipping? If you have an automatic transmission and it "slips" while you are driving it-that is, the car engine revs without the power going to the wheels-the most common cause (though not the only possible cause) is low transmission fluid. If the slipping is caused by low fluid, it will get worse as the transmission gets hotter.
Why Is My Manual Transmission Slipping? A standard ("manual") transmission uses fluid too, but leaks aren't a common issue; a standard transmission could lose all its fluid and never slip at all, though eventually it would lock up while driving down the road. If you have a standard transmission, and it's slipping-the engine revs but it doesn't transmit power to the wheels-the problem is usually in the clutch.
Further down in the article I discuss how to diagnose this problem.
Sounds Like Low Transmission Fluid to Me

The first thing is to check if you have enough transmission fluid in it. There is a dip stick and if you don't see any fluid on the dipstick, then add one half quart at a time and see if this helps. Also, there is a transmission repair fluid that may help such as "slip stop". List Transmission Treatments Additives Reilly Auto Parts

22's answer as to location is correct. Check the fluid after the vehicle has warmed up and with the engine running. Check your manual for fluid type if any is required (should be type "F"). Do not overfill as it will not help. If fluid is a qt low you ahould check transmission lines going from radiator to the tranny as there is a leak somewhere. Also look around the transmission pan for leaks. Slipping of the transmission is the most obvious indicator of low fluid, stepping on the gas but the transmission doesn't push you faster.

ther will be a drain bung on bottom of transmision box to drain

There's no easy fix.

Replace the seals

No,1 quart won't cause slipping

A bad lock-up Solenoid or Worn Converter Clutch, Might

OD is another issue

ANY SLIPPING-and you will be completely
rebuilding it ,in a couple months

Though most transmissions hold about ten quarts of fluid, the last quart and a half are very critical.
At about one quart low you'd begin to get slipping or disengagement on turns and below that most often the vehicle won't move or will slip severely. Always check fluid level with the engine at operating temp, running, trans in park, vehicle on a flat level surface.
Check and add using dexron III/ mercon fluid and look underneath and check to see where it's leaking
After repairing the leak (if it's a line etc) top off using lucas sealer and conditioner.(that will help if you glazed any internal clutches and will also help with any minor external seal leaks)
If you find a large leak, I suggest you bring it to a shop and have that repaired.
The amount of fluid loss and the length of time you drove it that way will determine how much internal damage was done. In most cases, what I said will get you back on the road but if you did major damage, the only solution is a replacement or rebuild.
Good luck!!

Depending on the amount of damage done driving it low on fluid you may be able to salvage more use out of it. The first thing you gotta do is change the filter and gasket inside the transmission pan. Check the owners manual and be sure to replace it with the correct type and amount of automatic transmission fluid. It might even help to get your local mechanic or parts store to recommend the best transmission additive available. After and only after you've done all this. You wait until low traffic time and drive it in the immediate area until such time as you can tell that it's shifting and not slipping at all. If it has "any" slip it will only continue to get worse. Don't let anyone sell you some 6 buck a quart fluid for the change unless that's the only one the manufacturer recommends. Good luck. This repair, if you are mechanically inclined and have a suitable jack to safely get under the car to change the filter, shouldn't be bank breaking. You may have to go to your local mechanic. But even a hundred or so is better than the pocket emptying transmission overhaul.

Its slipping ? Like the engine rpms go up and no go ?
Check the trani fluid - while the car is running in park..
Trani fluid is messured in pints on the dipstick - not quarts.. Be careful not to over fill..
Note; If trani is low on fluid to long and slipping to long - it is causing damage..

Hope this helps !!
Rate me good ;o)
