AboutRoland Finston Expertise I take questions about domestic Chrysler-product front wheel drive cars and minivans for the years 1982-2000 based upon my experience and shop manuals. I don't have detailed information (e.g. manuals) nor expertise for Jeeps, trucks, SUV's, import vehicles, or for years more recent than 2000.
I am available to take a question between 8AM CST and 9PM CST . If I am shown as "maxed out" try again later in the day as I add question opportunities one at a time so as to respond quickly, but I do have other responsibilities as well so may not be available for several hours at times. Try at 7PM CST as I will always be available for one question then.
There are answers to hundreds of Chrysler questions at your finger tips: click on "view past answers", one of which may be to your question as well; or put a few key words in the "search for" box, above.
Experience I have been a do-it-yourself auto hobbyist for 5 decades, and most recently have been concentrating on the various Chrysler Corporation domestic front wheel drive cars and vans. I have shop manuals and wiring diagrams for many models for the years '83-'00, as well as rear wheel drive cars for the early 80's. I enjoy analyzing problems that other Chrysler enthusiasts are having and sharing my information. <BR><BR><B>Organizations belong to</b><BR>Group co-moderator of the Yahoo autos group The Chrysler LeBaron Club<BR>

Question I used an OBDII scanner to check for codes on a 1995 neon coupe i'd just purchased, after it was idling harshly and wouldn't shift beyond 1st gear. It gave me the error code P0743(Torque Converter Circuit Electrical/TCC Solenoid Circuit). Is this a fuse or relay that needs to be replaced? Where is it located?
Answer Hi Derald,
The fuse for the solenoid is #10 (15A) in the fuse box, middle row, third column. The 12V wire is dark green/white on a plug at the transmission side that faces the front of the car, near the engine/trans interface. It is connected for start and run positions of the ignition switch.
The control of the solenoid is the orange/black wire from that same plug which goes to pin 79 of the powertrain controller.
That is the basic wiring for the solenoid which is inside the trans.
Roland
