2nd gear shift

turbo nasty

Turbo Dojo / MNTR
My car shifts a good "bark em" second but the problem is it is not consistant. It seems to shift a good firm 2nd shift when it's cooler but once it is warmed up it will still do it from time to time but not consistant. It is still a stock tranny with about 30-40k on a rebuild. My parents bought the car new and the convertor failed while under warranty so the dealer just rebuilt the tranny along with it. But the dealer had it slamming killer hard and my parents did not like that harsh of a shift so they took it back and I don't know what they did but it was toned down, anyone know what might have been done. Now this was years back and the tranny has always seen religous servicing and not beat on. TV cable is on the money. anyone I would appreciate some feedback thanks
