904 "braking" in 2nd gear

Hi,
As some of you may remember i had a problem with my 904 last summer due to not putting enough ATF in. I ended up getting the transmission rebuilt and put back in the car. Got about 120 miles on it, and now when the tranny shifts into 2nd gear, it feels like the brakes are put on. It is very clear that it is 2nd gear. it drives fine in first, shifts to second and feels like the brakes are on, then shifts to 3rd and it feels normal. I dont know what it is, possibly something internal?

the guy that rebuilt it for me earlier this year told me i should have a 727, but everyone here says that a 904 is just fine for what i need. It was a stock rebuild, so if it does need to be rebuilt again, i would like to find one of the guys that makes these things "bulletproof".

anyone know what is wrong?

anyone know someone within 150 miles of auburn, ny that is a 904 mastermind?

thanks,

Steve
