Yesterday I noticed the overdrive solenoid on my A518 has 3 wires coming out of it. What gives? Do I have an OD section from a gasser? The wire colors are: orange/white, black/blue, purple/yellow.
The build sheet for the truck says A518, and it surely is not a lock-up tranny. Any ideas?

 

When I talked to a couple tranny shops on my project they all told me that it was very possible that some 93's had a lockup trans. Both shops told me that they had seen them in person.

 

The funny part is the tranny does not exibit lock-up charactersitics. I have owned this truck for 8 years and since it had 30,000 miles on it. I always assumed it was the standard A518.
I was just getting ready for a converter and valve body upgrade for the tranny, now I am not sure what I have and what to order for.

 

What month of 93' was your truck made?

 

Are you sure it's the O/D solenoid and not the neutral safety switch? I believe that switch has three wires...at least mine does. The neutral safety switch also controls the backups lamps...that's why three wires.

 

Is it he connector that points up, or the connector that point towards the rear (sort of) that you're speaking of? The connector that points straight up is the O/D solenoid.

 

The connector plugs in on the driver's side of the OD housing. It plugs in toward the transmission, if that makes sense.
Last night I compared it to my dad's '92, definitely different.

 

Speed sensor? can't remember been a while since I've really looked at one

 

Not sure of the month of manufacture. The last six digits on the VIN are 169886. Does that help?

 

if it was a lock up couldnt you tell by the adaptor plate, wouldnt it be thicker to make up for the bigger torque converter..

 

You sure its not the sender for the electronic speedo?

 

should be on the door jam sticker.

 

The truck was built in June of '93. The wires I'm reffering to are about eight inches from the driveshaft u-joint, and plug in perpendicular to the driveshaft.

 

That's the speedo, not the trans OD connector.

 

And to further add to the confusion...

When McMopar had mine opened up, he found the VB had everything machined & ready for a lookup TC... just no wiring (inside)/plug (outside) to get it signal!
