Won't downshift into 2nd
 

Just got done getting H/C installed @ Speed,Inc. And when i test drove it the car would not downshift into 2nd gear. There's no problem getting it to upshift into 2nd-no notchy-ness or grinding. Also, it will downshift just fine into 2nd if i put into first gear (while holding down the clutch) and then bring it into 2nd. The H/C really shouldn't have anything to do with the tranny/clutch- neither have ever been touched. Any ideas?
