'93 Mustand with A4LD (auto) transmission.

Can a bad torque converter/transmission bog down the engine enough at speed to kill the engine? I know it can kill the engine when you stop but haven't heard of this happening when up to speed.

The car runs fine at low speeds (0-45 mph) and will go through 1st to 3rd gear with no problems, but when you get on it and it should be shifting to 4th gear; the RPM's go up for a few seconds then plumet down and the engine quits. Restarts fine. If you slowly bring up the speed it works most of the time and you can cruise 70-80 mph with no problem.

Been havingthis problem for over 2 years: See original forum post here: http://www.mustangforums.com/m_1315019/mpage_1/key_/tm.htm#1315019
and still haven't got it fixed. Had three mechanics look it over and all came up with nothing.

Thanks for any help.

Have you pulled codes yet? Its sounding like something other than the transmission because your saying it eventually gets there, but if it was the transmission you wouldn't.

Try doing a good look around the engine and transmission to see if anything is missing or broken

Have you tried cleaning the injectors since 2006?? It stopped doing whatever it was doing after the injector cleaner correct??

are you good at rebuilding transmissions...

Cleaning the injectors didn't help back in 2006, but I have cleaned them twice since then just to double check.

The only code we've ever been able to getwas P211 (PIP signal erratic) other then that, nothing and the check engine light has never come on. Have done visual checks and haven't seen anything.

Nope, not in the least. All I've ever done with a transmission is change the filter.

That is an ignition problem. It's the pickup for the signal to fire the engine.

Buy another distributer and put it in and see if anything changes

Would never give a smartass reply, that's why I said "Thanks, I'll take a look at it and let you know."

I "knew" he was referring to the two DIS boxes;)

He was talking about sleeper.

PIP is distributer, not DIS.

If its throwing a PIP and its DIS than its either your ignition controller, or a DIS box. Also look at your timing bet and your crank possition sensor

Thanks for all your input, i'll check those items noted above. Getting ready to move Monday so wont be able to check the forum awhile. Thanks again for the help.
