Article 13 - Delayed Initial 1-2 Upshift - C-4 Transmission

TSB #1 - September 15, 1971
(1972 Ford, Lincoln/Mercury - All Car Lines)


Delays in the initial 1-2 upshift for longer than normal distances at light throttle during cold start and drive operation are usually typical of a sticking governor valve. If the condition still exists after preliminary checks and correction, (if required) of the fluid level and manual linkage, replace the governor assembly.

In many cases the governor will become functional during the first 500 miles of operation due to the flushing action of the fluid. Therefore, if the customer prefers not to have immediate service, the condition will probably disappear.

NOTE: Some sluggishness in shift characteristics may be noted on 1972 models due to improved emission control devices.
