Torqueflite Band Adjustment

This is one of the most misunderstood procedures there is when it comes to Chrysler transmissions. Most people will shy away from this method simply because it does not involve torquing the band adjustment screw to "X" in. lbs. and then back it off "Y" turns. However, in my opinion and from my experience, using this method will give you results far superior to the factory specified method. What people seem to forget about the factory method is that the technicians at the dealership weren't concerned with performance shifts. They were more concerned about having a transmission shift smoothly to suit the customers.

To do this, all you'll need are wrenches for the lock nuts and a socket for the adjuster screws. You can also use this if you just want to adjust one band. First, assuming you'll be doing both bands, loosen both lock nuts and snug the adjusters. You should now notice that you can no longer turn the drive shaft in either direction. Loosen either of the adjusters until you can barely turn the drive shaft by hand. Once this happens, loosen the adjuster another turn and tighten the lock nut. Now, do the same with the other adjuster, only this time you should be trying to turn the drive shaft in the opposite direction. Once you can barely turn it by hand, loosen the adjuster another turn and tighten the lock nut.

Not only is this procedure just as easy as the factory one, it's also more accurate. I've always been of the opinion that the factory specs made the bands too loose - especially the front one since that's the only shifting band that makes a difference in shift timing. If you're still skeptical about how well this procedure works, try the factory procedure and notice how the shifts are. Then try this one and I would be willing to bet that your shifts will be firmer. This method not only works on Chryslers, but on any transmission that has a band adjustment.
