I don't think it uses a third gear accumulator. I believe the band is used in second gear it releases and the high gear clutch pack applies, when you shirt into third

Flair is caused by the applied releasing before the next one(clutch or band) to be applied applies. More than likely it is a timing problem with in the bands/clutches. Could be in the VB, too.
When I had a couple of coustomers that ran Comp with high powered P/G trannies we had just the opposite because of pressures it held the band on too long. You are probaby headed in the right direction in setting the band where it holds longer before the release. The next area to work is the high apply. Make it apply quicker. Since I'm not familiar with your tranny I'll just throw out some possibilities. Start with the clutch pack clearances. Any thing tighter than .0025 per side of clutch plate might cause drag when the clutch pack is not applied. If you reduce clutch pack clearance to the very minimum the high will apply quicker. You can also speed up the high apply by using a waffle or clutch plate that has oil slots. You can also window the steels to cut the oil off the plats at the time of apply. You can reduce the spring tension working against the clutch piston that is moved by the oil pressure. You can shim or reduce the volume of the fluid capicity in the high piston to improve quicker apply if there is a fluid volume/flow problem. You need to check for leaks in the sealing rings or the passages that flow the fluid to the high pack. Make sure the o-ring or seal on the high piston is not leaking.You might even look to see if there is a factory Vent/check ball on the high apply piston/drum that is leaking fluid on the apply. (Factories do that for soft apply in grocery getters). Next. VB springs on shuttle pistons and pressure pistons??? Working ot timed correctly. I'm not familiar with your VB so I can't get specific. When you get it where it has overlap then work backwards to eleminate it. Usually Overlap will hurt ET more than flair. It is also hard on parts life. Good
luck.
