As bad as the shift controller is and as bad as it's placement, it is VERY possible to replace the capacitors, any bad transistors, redoe all of the solder joints, fix any burnt traces, and reseal it. I agree that it *may* be better to "improve" upon it but the origonal unit can be made very reliable. Of the many I have fixed I have only had one not work right the first time. I have also helped many owners fix their own and in most cases (I assume depending on how handy they are with a soldering iron) they were able to successfully repair it themselves. Too many forget that you MUST do ALL of the On-Car adjustments and checks to assure the proper operation of the automatic transmission. They can be just as important as getting the shift controller to work corrrectly. In particular, setting the Line pressure and making sure the vacuum modulator is hooked up and working. The other very important point I want to add is that I have seen too many with burnt-up wiring harnesses. That is probably what takes out the power transistors. The wiring harness MUST be zip-tied AWAY from the exhaust pipes so it can't burn. Everything has to be done right to get the automatic transmission to work correctly for a long time. I not seen an automatic transmission actually worn out from use. They seem to last a pretty long time if they are taken care of.
