1983-84 FIREBIRDS WITH 5-SPEED MANUAL TRANSMISSIONS
Some 1983-84 Firebirds equipped with a 5-speed manual transmission may exhibit light gear clash during aggressive shifting maneuvers. This condition can be recognized by a slight crunch or click noise from the transmission as the next required gear is engaged, the duration of this noise will be very short, less than one (1) second, with the condition described. The condition primarily occurs during 1-2 upshifts and 3-2 downshifts. To repair this condition, the transmission will require disassembly and replacement of all synchronizer springs with new P/N 14085893. In addition, the clutching teeth of each respective speed gear, synchronizer sleeve and blocker ring should be examined for excessive wear or damage and replaced as necessary. The procedures to be followed for this repair are detailed in the appropriate section of the service manual.
