The only way a transmission can be overheated by a bad water pump is if the engine is also overheated, and if an engine is overheated that much it usually suffered damage. So did the engine also get really hot? Transmissions overheat when the cooler becomes clogged or a cooler line is crushed and the fluid flow stops, the cooler in this car is located in the radiator and you will need to follow the lines to make sure they are not damaged. The only way to tell if the transmission is damaged is to drain out the old fluid, repalce the filter, and either repalce the radiator or bypass the cooler in the radiator with an auxiliary cooler from a parts store, then fill the transmission with 1 can of TransX and then fill to specs with trans fluid. Now your going to have to fix the cooling of the engine so repalce the water pump if that is what has gone bad and the engine has not suffered any internal damage.

My water pump is no good anymore so you think if I put another water pump and clean out the transmission that it will work

I would drop the tranny pan first and see if there are any bits and or pieces of band or clutch material in the bottom of the oil pan, if there is no sense wasting any money going further it will need at least a tranny overhaul. But if it looks ok then go ahead and finish the service with a filter kit and fluids as mentioned, then go with fixing the water pump and installing another cooler for the tranny or replacing the radiator.

OK thanks going to do that now and let you know how that turns out

OK hope it works out.

OK just got done dropping the oil band for the tranny and I never saw anything in it... Its clean so is my tranny still good

Ok, then I would replace the filter kit and finish the service then onto the water pump and cooler.

OK but the little oil that came out off the tranny when I took the pan off and they transmission oil smell burnt should I have somethimg to worry about or can that be a problem

If it overheated just one time the fluid will smell burnt, that's why I recommended a can of TransX with fluid, it will help resoften the seals that may have been damaged and clean out any burn residue left from the fluid and yes there will still be burnt fluid in the torque converter that you cannot get out, so don't be surprised in a hundred miles the fluid will get dark, you will most likely have to change it again then and possibly one more time to get it cleaned up.

OK thanks so much for the help I guess I will put more oil in it and change the water pump and see what happens

If you don't fix the trans cooler it will over heat again and boil right out the dipstick tube and the vent, even though you have fixed the water pump. And if any of the hot trans fluid just happens to hit the exhaust manifold you will be in a ball of flames.

How do I fix the cooler for the tran I don't know if it messing up at all I thought it wasn't cooling because of the water pump if I have to do the tran s coolant line let me know what has to he done

Probably the quickest way will be just to bypass the one in the radiator, at the radiator you will see two metal lines attached, disconnect those lines and depending on the type of cooler you get you may or may not have to cut off the ends of the tubing to make it work properly, the instructions will guide you on the best way, then you may have to buy a install kit, as the parts person what else you will need to complete the install, things like clamps, push tabs, etc. it just sounds harder than it really is. The only thing that you really need to pay attention too is air flow, it has to have good air flow, so it has too be in front of the radiator. You can watch some videos on YouTube about Transmission Coolers that may help. HTH

OK so I have change the whole lines.. How I know if the lines are good or not

10

OK I done took off the water pump how do I know if the water pump is good or not once its off tho by looking at it nothing looks wrong with it at all

10

This my water pump I just took off do it look like it still good

If the tranny cooler lines are bad it will be obvious, kinked or crushed, water looks good check the weep hole if it shows and sings of seepage replace it.
