The powerglide transmission has a single band.  It is used to hold the clutch drum during low gear operation.  If the powerglide band is not adjusted properly the following things can occur:

• Band failure (burning of clutch material)
• Slipping in low gear or no low gear function at all
• Shift flare between low and high gears
• Car rolling backwards when the transbrake is applied

The powerglide band should be adjusted to the following specs:

• Tighten the band adjustment screw to 72 inch lbs
• Unscrew the band adjuster three and a half turns (3.5)
• Tighten the band adjustment screw’s locking nut

The band should be readjusted on a semi regular basis throughout the racing season.  BTE recommends using a heavy duty band adjustment screw to prevent band failure.  Stock band adjusters can bend and warp under heavy duty conditions.
