As a first time user, I'm hoping someone can answer a nagging tranny problem. I have a '68 camaro originally equipped with a 210HP 327 and powerglide. The 327 was completely rebuilt with fairly conservative parts (9:1 comp., Edelbrock Perf. cam and intake, World Prod. Stock 1.94/1.50 valve Heads, Tri-Y Headers, 600 cfm Holley) and the powerglide was replaced with a B&M rebuilt TH350 and a "Saturday Night Special" converter (stall approx. 300rpm above stock). The problem(s) is that 1st gear seems sluggish on acceleration, followed by a nice firm 1-2 shift, and then almost immediately afterwards a barely perceptible 2-3 shift. Also, the kickdown only operates with your foot almost through the floor? This engine has been professionally tuned and should be a screamer up to 4000 rpm.
