Question about 1991 Ford LTD Country Squire
Crnaks ok and idles but cuts off when put in gear in idle. recranks ok but must give it more gas when putting in gear to continue
Does it buck when you do get it to go into gear? Another likely possibility is the idle speed control is gone. If your idle speed is too low, you'll die when you go into gear. I'd look at that before you get too crazy with the transmission shops. It's a likely fix, and much cheaper than having your converter checked. Also, yes, you should be getting a warning for either of those conditions, however it's possible that A) the light itself might have blown (Yes, contrary to popular belief it can happen that the check engine and/or service engine lights quit working!) B) You may have a problem with the ECU.
The ECU problem is NOT very likely though. Certain emissions and electronic controls have a "tolerance" before they send an error message. In some cases, an electronic part can be just bad enough to give you trouble without being quite bad enough for the ECM or PCU to read it as a fault and send a code.
When in doubt, always have a look at the easiest to diagnose, and cheapest to diagnose, first. Save the big, expensive, nasties for last. This doesn't mean just to throw parts at it. Just keep things in perspective:
If a human being kept fainting, you wouldn't automatically jump to heart surgery.
If your car keeps stalling don't do the same!
The basic things a vehicle needs to run, are spark, fuel and air. If any one of those things is not being provided in the correct amount, you'll have problems with stalling, poor running, or just all out not starting.

Don't remember for sure but I think that has a transmitttion with a lock-up converter. AOD trans I think. If so the converter is in the locked-up mode. Not letting it free wheel when put in gear. Will need to take it to a transmittion shop or dealership to have it checked out. Might be just a sensor or maybe a converter that's bad. Should get an amber check eng light too. Being that the lock-up is computer controled.
