It's not just the transistors, it's the wiring, the design of the circuit, the workmanship, etc. I bring this up because we all know how how notoriously unreliable the shift computer is. An automobile's electrical environment is a difficult place for sensitive electronics to live. The voltage varies, people may jump-start impressing voltage spikes, maybe they accidently hook things up backwards and draw a nice big spark! I think your trying to improve the car is a great idea but you have to consider all of the things that could go wrong. If you go ahead with this other owners may not be as careful as you are with your car! Also remember some people's cars have had their wiring modified so on some cars there is no "Plug and Play". Maybe an owner is running on a bad fuel pump that is drawing way too much current. If you offer this as an "improvement" you have to consider what may happen once it gets "out there". Your relay will get blamed for all of the problems that the car has. Just look at all of the problems DMCH is having with their new headlight switch!!!!!!! Even Zilla had some problems with their stuff and it was considered excellant. You really do need to do a lot of testing on a lot of different cars so your can be confident in your relay.
