Shift Kit for a 727

The Trans-go TF-2 kit is the best shift improver kit there is but the only problem is since yours already has a TCI kit in it that means the transfer plate was changed. That's the way TCI does it. The Trans-go shows you how to modify your stock transfer plate, along with changing springs, adding a spacer to the rear band servo, modifying a couple valves and adjusting the line pressure. To do it correctly you need a stock transfer plate and I don't know of a place that sells them. You'll probably just have to locate a used one. With the Trans-go kit installed and the accumulator blocked you'll have a pretty snappy shift. Not as quick as a manual valve body but as good as it gets with a stock valve body. That's what I have done to my trans. and barks them in 2nd real good and 3rd it don't bark em but is very solid. Of course I'm already going 80 when I hit 3rd so not many will bark them at that speed. The only other option to get a more performance oriented shift is to go with a manual valve body but that eliminates the automatic shift feature and you'll have to shift it yourself. If you do go that route make sure it has "low band apply". Most of the ones marketed today have this but a few still don't. Without low band apply it's a safety hazard on the street.
