Re: tv cable

Don't drive it this way, you will kill the trans! The TV cable does so much more than just kickdown. Running around without it, you have only around 50 psi line pressure, while normally you need around 200 at half-throttle. You don't always get that, but 50 psi at full throttle WILL kill the trans. I've been there, done that.

It can, but usually does a pretty crappy job if it does. From what I know the tv cable is the low tech method of the engine telling the trans what it is doing. It controls shifting a lot more than some people give it credit for. I remember when my tv cable was out of adjustment I could hardly get the thing to shift out of second without peddling the throttle.
