904 Accumulator Spring

Actually my original statement was to put it back in for his use.
Transgo, now say to use it, I guess after continued development they found it was of no great importance.
I think overlapping shift timing is going to cause more wear in the trans than the use of the accumulator spring ever would. If you use a shift kit designed for a spring and then don't use it then maybe your also creating extra wear. I think in the big scheme of things it plays a very minor part.
I guess people can make up their own minds.

All possible, and good points.
Shift firmness and overlap can be dealt with easily by opening oil passages for apply or release oil flow, but in the factory form the accumulator makes it a little more forgiving on possible 1-2 overlaps, so you are right on that point.
The spring can mean the difference between a second gear tire bark or not.
Really the main reason they put accumulators in there in the first place is because of old ladies wanting the shifts nice and soft in thier big old boats.

All in all you are correct of course that it is a personal choice.
