[DML] Re: AUTOMATIC TRANSMISSION STARTING OUT IN 2ND TILL IT WARMS UP???? HELP PLEASE

[doctorDHD@xxxxxxx]

I agree with Dave T.  It's the shift computer that tells the tranny what gear 
to be in.  You may want to add the solenoid indicator lights that display 
what the computer is telling the transmission.  

When I replaced my computer I moved it into it's own small box on the 
driver's side wall of the engine compartment as I did not want to have to play with 
it under the car.  As Dave T said I also had problems with the little ribbon 
cable that connects the two circuit boards.  It it very stiff and fragile.  I 
just replaced it with individual flexible wires.

I also had a similar temerature / shift problems but mine wouldn't shift into 
third until it warmed up. The added solenoid/shift lights confirmed that it 
was the computer and I was able to make a test generator with a 9 volt battery 
and a 10 turn 100K potentiometer.  With that connected to the input of the 
computer and the solenoid lights on the output I was able to test the system 
without driving the car.  I found that slightly flexing the individual circuit 
boards would affect the shift points indicating bad solder joints. I also noted 
that just touching the boards with my fingers would also affect the shifts so I 
ended up wearing latex gloves.  I was not able to trace the exact bad joints 
so I resoldered most of them and that fixed the problem.

If you need more info don't hesitate to contact me.
