I just installed a TF2 kit this last weekend. This was my second one i have installed, last time i cranked the line pressure six turns instead on the four they recommend and mine shifted super firm, its the best tranny kit I've ever installed.

So my vote is the TF2.

Only difference between TF2 and TF3 is that TF2 still allows the tranny to auto shift. TF3 turns the tranny into full manual, but still retains the kick down linkage to regulate throttle pressure. Stomping the pedal with a TF3 will not "kick down", but in a TF2 it will...if properly adjusted. I have a TF3 in my Demon's 727 and it shifts VERY firm 1-2 and 2-3. Almost too firm 1-2 because under WOT she gets VERY squirrely kicking into 2nd.

Some overlap on the 2-3 shift is crucial to the operation of the TF; like John stated, without a slight amount of overlap there would be rpm flareup.

This is why the TF is inherently inferior to transmissions (like the TH400) that have no release/apply operation.

So your talking more about the street strip version? The Griner style transbrakes eliminate ANY overlap that is associated with the torqueflite!

OK, let's look at the physics; the valve body has no way of knowing the band lever ratio, the band adjustment, the front clutch clearance, the front clutch spring pack, etc. all of which contribute to the 2-3 shift overlap or lack of.

To say any VB will eliminate ALL overlap is good advertising but not very realistic, more likely is the claim to eliminate excessive overlap.
