How can you tell if your soleniods is bad on a 96 chevy truck transmission

SOURCE: I want to switch transmissions

If they are both 4L60Es' then yes. I know the 96 1500 does but you didn't state what size the 97 is. And are they both 4X4?

SOURCE: Where is the kick down soleniod located on 1998

it should be around close to your battery or the alternator if not then it is by your starter depending on its position determines the difficulty of replacement! good luck!

It doesn't sound like a solenoid, check the universals and if it's not those, it is more than likely a linkage problem,

Please rate this answer. Thank you.

You don't say what kind of transmission you installed in place of whatever transmission you took out. 4L60E, 700R4, etc.

You probably have a mess on your hands. If your replacement is pcm controlled, there is no practical way to override the pcm for transmission control. It does all the work that shift valves did in older transmissions. You NEED the pcm involved. I guess you COULD bypass it with a set of switches, but then you'd need a co-pilot to work the solenoid switches while you drive the vehicle.

There are add-ons available that will adapt transmissions for racing, show car building, etc but they are a bit of work, a bit of money, and require some understanding of electromechanical systems on transmissions. Might start at tciauto.com or google trans adapter harness.
