2-3 shift prob??

[1985GN]

olk guys here it goes i had the tranny rebuilt not too long ago maybe 3 months. well after it was rebuilt wiht full race stuff i noticed that the 2-3 shift was flairing and not shifting hard. so i took it back and he looked it over and knew that hte piston that was with the billet servo i had was the wrong length or something. so he had the car for a day played wiht the servo and the piston and handed it back to me. hte car was perfect tranny shifted hard as i liked in all gears not matter if it was cold or i beat on it back to back to back. well lately the lazy 2-3 came back but in a different way. now if i cruise and im on the gas 1/4 throttle it shifts nice and firm. at 1/2-3/4 it flairs and slips and is all over. at WOT when i shift it it hesitates then hits into third with a little bit of a nice shift. is this servo still the prob??? te fluid did not smell burnt and i did a flush on the tranny wiht new filter. the filter didnt have barely any metal in it. plus can someone explain whats going on in a tranny on the 2-3 shift? thanks for any help on this matter.

*DIRECT DRUM:
The direct drum must be within .030 of original diameter. Cannot be bent or heat deformed. DO NOT drill holes in band surface. This does nothing but add problems with band oil, the direct clutches slinging their lube out, and I have even seen them crack from the holes, and distort the actual drum itself.(Like a brake rotor) Weakens them immensly. All steels must slide freely in bore. In ring bore, no ring cavities can be present. One of the most common 2-3 flair symptom is , bore is ring grooved near bottom of drum using cast iron rings. Band surface must be PERFECTLY FLAT, no scores, especially with the use of the new band. Teflon rings are recommended and almost a must.
USE OF MULTI or EXTRA CLUTCH PACKS HIGHLY NOT RECOMMENDED!!!!!
The theory does not work. You will cook them,every time. We have spent countless hours testing theories and clutch materials. With the steels at .090 or thicker in stock form,they work perfect. 6 Clutches with stock steels set to .038-.042 end clearence will work flawless!!!!!! We recommend Alto Red Eagle clutches for stock and hd rebuilds, and Raybestos Blue Plate clutches for street/strip and strip use. ( Again, use of Kolene steels is not recommended. Stock .090 and thicker stock steels are just fine and must be flat.)*
