Have Ford Questions? Ask a Mechanic for Answers ASAP
Hi, My name is ***** ***** for the delay.
I will do my best to assist you.
when you put into gear,does it jump into gear really hard?
does it kinda feel like a manual transmission with the clutch let out when you put into gear?
but it idles and seems to run well?
does the engine light stay on?if so,can you give me the computer codes?
does the brakes feel right?
i would think that sense you did hear a hissing noise,,you first need to check all vacuum hoses/lines..but.
from the way you explain,the problem may be the torqe converter ,,it may be staying locked up.this is why it dies when you put it into gear,,the converter may have no slippage

sorry,i was off line
there isnt anything you can do with the converter to un lock it,,you will just need to replace it
the converter isnt likely to be new,it is likely to be rebuilt
did you replace that converter trying to fix this problem to begin with?
stand by,i will opt out,maybe one of the other guys has a better idea of what is going on here
Hello, my name is***** and thanks for your question.
Overfill the transmission by 2 quarts, start it and see if it still stalls in gear. If it does not then pull the pan and check the filter. It probably has fallen out of the pump or has a large crack in it.

Is there a reason you keep viewing my posts without replying?
Ok sounds good. You have to put a full 2 quarts to get it above the pump inlet, assuming it is full.
Find anything out?
Its going to be a stuck valve in the front pump, either a converter regulator valve or converter clutch control valve.
It could be the converter itself but that is very rare.
Was hoping you would get lucky and find the filter cracked or fallen out or somebody changed the filter and did not get the original filter o-ring out of the pump resulting in double o-ring in the pump. Seen that several times also. Usually overfilling by 2 quarts rules all those possibilities out because the high fluid level covers up the leak.
Yes they are both difficult, the trans has to be removed, the front pump removed and disassembled. Should be performed by an experienced transmission technician. Once apart it should be no problem seeing which one is sticking. Not sure if parts available still for this trans. Click link below for an exploded view of the pump assembly.
