I realized the other day that my recently installed new TH350 tranny wasn't shifting out of 2nd...It occured to me that I really tightened up the kickdown cable.

If I would have tightened it too tight so the tranny was always in "kickdown" mode, and when I accelerated, it was pulling beyond the amount needed to just drop a gear...could I have damaged my tranny?

I can't test anything right now becuase my car is up on jackstands getting a new rear-axle.

Usually if you have it too tight, you wont get full throttle either. Not a great thing, but transmissions can take a lot of RPM.

The newer transmissions like the 700R4 can be damaged by having the throttle position cable too loose, since it controls internal shift pressure, not shift points like the old TH350.

I would be worried about over-reving the engine.

Thanks...I definitly havne't over-revved the engine yet...since it is my first project, and I did it all....I'm really nervous about driving hard so I haven't run it through its paces yet.

I'll loosen it up before I drive again...and hopefully I'll find 3rd gear.
