RE: {Chrysler 300} 57 torqueflight rebuild

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.
