As a follow up to our previous blog posting, the other common problem with transbrake operation in powerglide transmissions is the transmission moving in reverse when the transbrake is activated. Again, this can cause the car to roll out of the staging lights causing an instant loss.
Once again, we will review the normal transbrake operation:
solenoid pushes the brake valve to a position in the valve body that
pressure from the reverse piston and clutches. The car now has forward
movement in low gear and accelerates down the track.
If the car is moving backward any during the transbrake setting and
staging process, it is likely due to one of the following problems:
OEM or weak pumps need additional RPMs to move fluid quickly and
adequately to apply the reverse clutches. Increasing your RPM before
setting the transbrake is the first solution to try.
Check these areas if you are having transbrake trouble in your powerglide transmission. These are simple fixes! If you have any questions, contact our technical department @ 1-662-851-3213.
