Nice fix and nice car. Glad it was simple. Sometimes your first suspicion is correct: "The short list is that the band tab is out of position..."

By the way, you can check your throttle pressure adjustment by road testing the car. On nearly full throttle acceleration, you should feel it shift from low to high without the engine revving any higher once it began the shift. If the engine flares up then the adjustment is too low. If the car does not come out of low until 50+ mph then you are either on the gas too hard, or your throttle pressure is very high, or your linkage is set to the wrong hole.

Then, when coasting to a stop, the downshift to low at about 6mph should not have an obvious engagement. Since pretty much zero power is transmitted when that shift occurs, they made it very soft. If not then your throttle pressure is too high.

Here is the linkage under the hood. Note the linkage "A" near the bottom. It shows an optional extension kit held on with 2 screws. You should either have it in the top hole where the one screw is, or in the extension kit hole.

Let me know how it goes. Might as well get it good so to have the nicest shifts and least wear from the start.

To late now.

But Ross's shift mod is the way to go
