adjusting shift points

[gotdust57@yahoo]

how do i adjust the shift points on my passing gear linkage, i put old style linkage on the type with that screws in and out and now i dont shift from 1st to 2nd until 30mph and i went up to 55mph and still wont shift into drive, i didnot go any faster because it was winding out to much anyhelp? thanks

with the motor off and the carb throttle in the idle position pull the kickdown rod all the way forward, then adjust the front piece on the kickdown rod so that the back of the slot just fits back on the carb linkage. if it's a tad mushy lengthen the rod out a bit until you get the shift your looking for.

On the screw in adjustment piece attached to the throttle lever on your carb. shorten its length( less threads exposed ). The longer it is the more delayed your shifts will be. Here are some linkage diagrams of various setups. http://www.moparts.org/Tech/Archive/auto/35.html

do i put a nut and bolt in slotted spot on screw end of adjuster to hold it in place or does something else hold it there? thanks

If your talking about where it connects to the carb. that gets a special stud. Sorry I don't have a pic of one but it shows it in the link Oldschoolcuda provided. It's not real easy to see but if you look close at the carb. you can see it.

A spring was added to some throttle pressure linkages to keep the weight of the linkage from adding MPH to the upshift at part throttle as well. Something you may want to try.

If you adjust more slack into your linkage, you will shift earlier and softer. BUT and I do mean BUT, you will potentially shorten your transmissions life. By reducing the throttle signal to the transmission, you reduce the line pressure, which reduces it's torque holding capacity. However, if the linkage is to "long" the transmission will think you are under a higher load and raise shift points and firmness accordingly. If the linkage is way to long, you will not get full throttle at the carb.

Here's the basic thing to look at with the linkage. The lever on the transmission should JUST touch it's rearmost stop when the carb JUST hits wide open throttle. So long as you are using some version of a Chrysler compatible carb and an unhacked OEM linkage, you should be fine. A factory service manual will have a great picture and instructions.

If you set it per the above and your transmission will not upshift, you have some other sort of problem, such as a screwed-up governor or a $40 shift kit.

No need for a jam nut, the linkage cant rotate once connected.
