Post th350 troubles

the trouble is the transmission in my truck only shifts 1st-2nd under full throttle if I take off in 2nd, otherwise in drive and full throttle it's 1st-3rd every time not even a hint of 2nd gear. it also drops my rpm in 3rd to a max of about 4500, but it shifts from 1st-2nd at about 5200...
I would kinda like to fix this if there is an easy remedy.
Thanks for your input

I should also mention that it has a shift kit and appears to work just fine under part throttle, shifts nice and crisp and shifts really hard when I'm in 2nd, it's just when I drive in drive, there is also no kickdown hooked up.

The kickdown does more than just kick down to second on hard acceleration. It gives a throttle position/engine load signal to the tranny at all driving conditions. That combined with the governor tells the tranny what to do when. You are depriving it of needed info.

thats what I like to hear, the kickdown cable is laying on the intake, I have an edelbrock carb and they dont look like they mate (the cable and my linkage), I'm looking in my haynes book right now to get an idea of how it works (this is my first automatic). I do remember the last time I played with it (the kickdown cable) it seemed to be stuck.

ok it says that I should try to check it with the vehicle idling and in neutral, and the cable should move freely forward. this will have to wait until it stops raining out. all I need to do now is find a way to attach it to my carb.

They don't have a real long stroke so what you interpreted as being stuck is probably just a shorter stroke than you expected. You will need to find someone with an Edelbrock carb/TH350 to see how they set it up. Should be easy - there has to be at least a gazillion rods out there with that setup. Maybe Edelbrock tech line can advise you on setting this up. The only combo I have done that is similar is an Edelbrock w/ a TH400 but that tranny uses an electric switch, not the cable. I think you should be using the big hole in the top of the throttle arm for your throttle and the little hole on the bottom of the arm for the tranny cable. At least that is how the Holley carbs are designed. Go to the Edelbrock web site and ask them, thy will know.

Willys36 thanks for your help.
I've had sm465's in my last 3 trucks and before that I had an m21 in my firebird, I'm not too impressed by automatics so far but the local dragstrip only has wednesday night bracket racing for street class.
