1997 trans computer

Does the 1997 auto have a stand alone computer for the transmission like a 93 idi turbo?

I have access to a 1997 7.3l auto with a blown motor. I can get a 7.3l idi with a turbo that has been rebuilt very cheap from a friend. The idi is a 5 speed.

I'm trying to figure out if the 94 idi will work with the 97 auto. Thanks.

No the trans controller is part of the pcm.

Don't know of anyway of making it work with out swapping the entire engine and trans harness and computers. The 97 trans computer depends on inputs from the engine pcm.

Thanks. I will have to get pedals and links from a junk yard (car-parts.com) I love the body style of the 97 and the simplicity of the idi. I know it normally doesn't make sense but the truck and engine are under 1500.00

I have a friend with a '97 PSD with auto transmission. The PCM is fried. Evidently, Ford does not make them anymore. He also can't find anyone who either sells them or can repair them. Can you guys help? Two mechanics are stumped. One guy is a former Ford stealership transmission technician. otherwise, the truck appears to be junk. thanks.

Try craigslist, ebay or salvage yards. It doesn't have to be from a 97 but it will need to re-flashed to the 97s calibration. How did they figure the the pcm is fried. Has the dealership tried to re-flash?

the mechanics tried other PCM's and claimed they could get the engine to start but the tranny would not function. Other PCM's...and the engine would not start. I do not know if they tried re-flashing it or not but I think it is just plain bad/cannot be repaired. I need to ask more questions. not sure if the dealership has been involved either. thanks for all the tips!!

The trans computer is separate. If the engine starts and runs on a pcm I would go from there. The pcm needs to have the correct calibration to talk to the trans computer.
