Re: {Chrysler 300} 57 torqueflight rebuild

Cannot agree more with John. You must use the shop manual regimen for throttle linkage adjustments and throttle valve adjustment and the procedure is what it is because it is interrelated. It is also rudimentary as such linkages go and as such must be set up right. All automatic transmission diagnosis should start with fluid level and throttle valve rod adjustments.

yes — but if pedal angle not right , just setting it that way alone can be all wrong , It can limit wot or not move enough or fast enough toward WOT . Or carb plate movement is not synced right to trans pressure . people have often messed with say one adjustment only , —- often , —- over the life of the car before you so it can be way out . Three adjustments DO all interact right?

They had so much trouble with this , in 60 they made those holes in firewall bell crank that you lock bell crank with a rod so you know where you are at start . Earlier linkages are a lot more complex than it looks to really get right . I got into this while making a new gas pedal repair pivot of stainless and aluminum to fix the usual rust mess , wobbly pedal at floor ( Forward Look parts )

I think i noticed by comparing F to earlier that one arm is level or almost so at bell crank at zero , meant as observed info not instruction .

Ram setup section has good overall linkage info too .

Remember it is NOT linear movement , the arms are all at angles . We should be just using the book exactly , ( really!) although some years are way better than others on this . Some much too brief .

You really have to do it in exact sequence of FSM or you can screw it all up , been there and very frustrated at times , despite years of working on this . Average mechanic uses his own ideas , not the book .

forget that . start over.

That's what I said

The kick down linkage

Controls shift speeds.

If you make the rod longer

It will shift later vise versa.

The transmission throttle

Lever should be completely

Forward when carb is at curb

Idle.

So…I pulled an article from the Tech section entitled Torque Band Adjustment by Mark Eisenhart. Turns out the article is about the softness or firmness of the shift.

My 300C shifts from first to second at about 11 mph, then shifts from second to third at about 20-25 mph. The engine is not that happy in third gear going 22 mph. What you are saying is that I can change the shift mph by adjusting the throttle rod up or down? The manual says proper shifting is 15 to 30 mph 1^st to 2^nd, 20 to 60 mph 2^nd to 3^rd.

I changed the intake manifold and carb on a Newport years ago and did not adjust that throttle rod- was surprised when the 727 shifted differently (late). Didn’t realize they are set to things like that but it really does affect it.

Our 64 Newport shifts a little late when cold only when it’s either

1) low on ATF or

2) has been sitting a while.

WRT 2 above, does the torque converter drain out after sitting and cause that? I wonder if that could be part of Gary’s issue (if there are internal seals that might be leaking too much) but I’m not familiar with the mechanics of the 727 yet.

Gary, I know Don Verity usually pays attention to the listserv but you might call him about this and talk it through first. Also, did you adjust the throttle rod to the shop manual specifications? Very important.

To all great folks in letter car land.

It has been suggested that the delayed upshift from 1st to 2nd may be caused by a worn spring in the kick down governor assembly.

I understand the 300 spec'd different springs/weights compared to other cast iron 3 speed torqueflights used in other mopars in 57 & 58.

Is there a source for the upgraded spring/wt parts for the C?

Any leads will be appreciated.

Thanks to all.
