[DML] Transmission Computer, Again



 
 
Steve,
 
What is it that you are trying to do?  Attached is the schematic I  have.
 
I know it can be frustrating working on the AT governor as it often seems  to 
have a mind of its own.  That was one reason I moved mine to the drivers  
side of the engine compartment.  Easier to get to it.  The usual  problems are 
the blown caps, but once you open it up and remove the boards you  have to deal 
with broken wires in the little ribbon cable that connects the two  printed 
circuit boards as well as other intermittent solder joints.  These  bad solder 
joints were not visible even with a magnifier.  I replaced the  ribbon cable 
with a number of thin flexible jumpers and carefully resoldered as  many points 
on the PCB as I could stand and I haven't had a problem since.   Of course all 
these things never solved MY original problem which was that  occasionally 
the tranny  (seems to ) decide to shift into neutral when in  third gear and I 
"give it the gas".  With the tranny solenoid lights  installed I have found 
that the lights stay off, i.e.. not telling the tranny to  shift out of third, so 
I suspect an internal mechanical problem.  One day I  will do what Dave T 
said and check the tranny pressure.  I have the gauge  but....
 
So again the question is what are you trying to do or solve?

Group,

Does any one have a schematic or any type of  electrical drawing on the 
automatic 
transmission computer?  Even a  partial drawing on a napkin will help.  I am 
trying to figure 
out a  broken computer.  According to the archives, doctorDHD or Mark Hershey 
 have some 
pretty good ideas on how the thing works.

Also, anyone  thought about just replacing the computer with press buttons 
and mount  
them on the steering wheel?  A couple buttons on the steering wheel  (like 
the Audi sports 
shifting) are certainly more rugged than the darn  computer in the  
transmission.

Thanks.

Thank  you,
