It has been years, but I finally installed this transmission on Friday.
Initial driving impressions are good. No gear whine, leaks or other oddities. Although I noticed the closer ratios at part throttle, most would not. Time to inspect my antique drag radials, and see if they will be soft enough for 1 more weekend. Track results and WOT impressions pending. |

Do you have any mph/number comparisons yet for the ratio change? Both actual ratios and results from driving?

3rd gear remains 1:1 and 4th gear remains .70 so cruising is unchanged. |

1st and 2nd are the key, though. I think the stock 1st gear is 3.06 and I hate the shift from 1-2 at 8 mph.

Now it is 2.84 for first, and 1.56 for second. On paper, pretty nice. |

They market and distribute it, but Chris at CK Transmissions was the brains behind it, and is responsible for the manufacturing.

That sounds more like a 4L80 ratio set...

It took much longer than I thought, but a quality aftermarket company has knocked off the original gearset.
Less than 1/2 the price I paid, and in line with the price of other transmission types (Turbo 350, powerglide, Turbo 400 etc). http://www.sonnax.com/parts/3734 |

Ran out of summer, so no track times yet.
Street driving only. |

Any impressions as far as driveability? I want to know what difference it makes in the 1-2 shift in a real world application.

The butt dyno does not notice much of a difference.
I have quite a few datalogs from the last trans, so not only will I be able to compare ET differences, but I "should" be able to quantify the shift point increases (or decreases). |
