Help! What did I do wrong? (kick down)
Morning all. Even though I'm getting everything together to change the TH350 tranny in my '67 over to a 700R4, I wanted the kick down linkage to work. I've been just putting up with the fact that it didn't work.
I pulled the kickdown cable, the bracket that mounts to the intake and the hook-up at the carburetor off of a '72 C10 that came factory equipped with a TH350. The one that's in my '67 was transplanted in. So, I get the non-functioning linkage (it wasn't hooked up at the carb - and wouldn't fit) off of the '67. I did notice that the vacuum modulator wasn't even hooked up to a vacuum source ![]() So far, so good. Then I take it out for a test spin. The thing won't shift out of first gear! WTH? I take the kick down linkage loose from the carb and take it back out for a test spin. It STILL won't shift out of first. I fiddle with the linkage to make sure that it wasn't pulled out (engaging the kick down, and take it back out for a spin. It STILL won't shift out of first. WTF?!? Help!

The kickdown only operates the downshift at WOT. The modulator sounds like it needs to be changed.

Yeah, I think that it does need to be changed. The thing is though that it wasn't even hooked up before and the tranny shifted fine - harsh from the shift kit - but fine.
I'm not a tranny guy. What does the vacuum modulator do anywho?

Okay, she's fixed now.
Apparently, I was mistaken about the modulator not being hooked up before, but the tranny still working. That's what I get for trying to do too much at one time. Thanks to longhornmail and slam33 for pointing out that the vacuum modulator does, in fact, need to be hooked up ![]() Man, with the kick down hooked up this truck really hauls. I can't wait to get a 700R4 in it. Then I'll have a rocket launch AND a comfortable hiway cruise. Always something to do on these old trucks. Great, ain't it!?! Thanks again guys. Jeff ![]()

Well, you'll get off the line ok, but I'll be passing you with my 200R4 in second while you are hoping to rev up till the cam kicks in cuz you are bogged down.

Terryp, how much HP/TQ will the 200R4 take? I don't think that it'll take as much as a 700R4.
The 406 that I'm building should make about 500 ft-lbs of TQ and almost as much HP. What it'll take is the deciding factor with me.
