Re: Auto trans ARRRGGHHH

>From what I have read, heard from other owners and my direct 
experiance the problems with the shift computer appear to come from 
two main sources, 1 blown capacitors, and 2 cold solder joints. The 
repairs are obvious, replace the caps and resolder the board. I have 
heard of the transistors blowing but it is rare and if that happens
it 
cannot shift into 1 of the gears so if you have all of the gears even 
intermittantly the most likely problem is cold solder joints. The 
multi switch can even go bad but that is very unlikely. Don't rule
out 
the connecters to the big plug on the firewall, a bad connection
there 
can cause intermittant shifts too. The trans needs 12 volts so if it 
doesn't get it or the connection is "iffy" it can cause weird shifts. 
Be careful a bad shift computer can put a lot of strain on the trans 
with all of the improper shifts and damage internal parts.
