How do you adjust the bands on a c6 transmission?

Adjusting the bands is a straight forward process. Just get the car safely up on jacks. Locate the intermediate band adjustment (the front one), loosen the locknut, torque down the adjustment screw to 10 ft lbs and then loosen it exactly 1 1/2 turns. Tighten locknut.

What do the bands do in an automatic transmission?

Automatic Transmission Bands The lining absorbs transmission fluid to aid in heat dissipation. As the band tightens around the drum, ATF flows into grooves cut into the band’s surface, helping to cool the fluid as the band brings the drum to a stop.

Transmission Band Adjustments As the band tightens around the drum, transmission fluid is squeezed out into grooves cut into the band’s surface. The band brings the drum to a stop and holds it there. When the friction material on the inside surface of the band becomes worn, the gripping ability is affected.

What causes a automatic transmission to shift hard?

Transmission Fluid Low or Poor Condition ” Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.

What does a kickdown band do?

Although the name implies that it should “kick down” gears, the primary role of this component is to shift up into higher gears as the vehicle accelerates. It comprises of rubber and metal and is attached in the transmission and will engage when a gear shift is about to occur.

How do you adjust a Powerglide transmission band?

The powerglide transmission has a single band….The powerglide band should be adjusted to the following specs:

How does powerglide work?

In an automatic transmission, gears are arranged in epicyclic gear sets, also referred to as planetary gear sets. The Punch Powerglide 6 speeds offers six forward speeds and one reverse speed by combining three planetary gear sets only.

How to Change the Fluid in a Powerglide Transmission

What does the servo do in a Powerglide?

The Sonnax Smart-Tech servo advances the Powerglide transmission to new levels that back up extreme horsepower with never-before-seen reliability. If you’ve upgraded other components and are still struggling with servo-related problems, the Smart-Tech servo is a key piece to solving this puzzle.

How much pressure should a powerglide have?

In a powerglide, most setups should see anywhere from 45 to 100 PSI. This will vary depending on the input shaft, pump, and converter combination.

How do you check pressure on a Powerglide?

You can check line pressure by installing a 0 ” 300 PSI gauge into the 1/8″ NPT pressure port located in the servo cover on the passenger side of the transmission. The servo cover is the triangle-shaped blue cover attached to the case with three bolts.

How does a transmission servo work?

It tightens to engage the gears, and loosens to release them. This type of transmission also uses a servo piston to activate and deactivate the bands. The transmission turns the output shaft, which in turn spins the axles, which in turn make the wheels go. There are a myriad of ways to do this.

For low fluid levels, you’ll need to add more fluid to repair the problem. For burnt or damaged fluid, you’ll need to drain the exhausted fluid and replace it with new fluid. For a leak, however, at least part of your transmission will need to be resealed to prevent further slipping and transmission problems.
