A-466 Cast Iron Torqueflite band adjustment without Torque Wrench .

[Bucket]

Would anyone be able to tell how to adjust the bands without a Torque Wrench .
How many turns back from when adjusters are snugged up .
I am getting different results while googling .
Transmission is still in the vechicle .
Cheers,
Greg

There are guys that do it without a torque wrench, but if you want to, you can improvise a torque wrench pretty easy with a fish scale and knowing the length of the wrench.

Torque is radius times force. Example: 10 lbs applied to a wrench 12" long equals 120 in/lbs. You need to use the measurement units in inches and pounds for torque value in in/lb.

Mark the wrench where you want to attach the fish scale and pull the wrench with it to torque the adjuster. Use a longer wrench or extension if your scale doesn't go high enough.

In many cases, "Google" can be your friend. BUT, in this case, www.jholst.net can be your best friend (might need to manually enter that address). Chrysler factory service manuals and parts books. 1955-1965, but mostly related to the Chrysler 300 Letter Cars (on the service manuals and such), but Chrysler only built ONE parts manual for all of their cars.

As to torque amounts, there are "foot pounds" and there are "inch pounds".

Enjpy!

Torqueflite Band Adjustment

When the band adjuster is first torqued down to a certain value, that is applying the band full on (which is where the driveshaft turning comes in to play). From that point, then back it off a certain amount and lock it down with the lock nut.

The "backing off until you can just turn the driveshaft by hand" is like backing off the adjuster on a drum brake after tightening it until the drum can't be turned. Backing off the adjuster so the drum turns freely results in the final adjustment.

I am presuming ALL of these adjustments should be made with the transmission at full operating temperature?

Certainly, these "shade tree methods" can and do work. As the OEMs will use torque amounts to put a more professional face on things, for dealership purposes.

To me, "performance shifts" include an elevated shift point, and with a higher line pressure. None of which apply to band adjustments per se. Deleting the accumulator spring can "harshen" the shift action, though.

Whatever works,
