Shift Kit?

[Unofficial]

Has anyone ever installed a shift kit in a 700R4 transmission? My friend has a 4L60E that he put a Transgo kit in, and he took me for a ride. I really like how it shifts. It's real firm and quick, unlike my slow shifts that just slip into the next gear. I found a Transgo kit on Summit for about $75, and was wondering if it's worth it, or if it's something I shouldn't really waste my money on. The transmission has a little less than 90K miles, and there's a rebuilt 350 sitting in front of it. Any experiences or ideas you could share?

I've used their reprogramming kits and parts many times. They correct a lot of problems and you should do it.

Add a Corvette servo also.

Check out the installation video to make yourself more comfortable with the idea of installing a shift kit.

Is there any truth that the harder/firmer shifting causes more wear on the transmission?

The general concensus, based on what I've read/heard is firmer than stock shifts actually decrease wear due to less slippage (stock shift calibration tend to aim more for comfort at the expense of some longevity), but there is a limit to how hard.  I don't see how super hard "bang" shifts could possibly be good for trans, u-joints, axles, etc.  And what good are they if you break traction everytime it shifts?  That's just less energy spent on accelerating and more on heating the tires.
