Linkage adjust
if it is automatic then this would be caused by shift down is not working in transmission
you have to put your foot on the break pedal, to shift out of park its a safety feature
clutch plates could be welded to gather
A bad first speed overrun clutch.
Throttle position sensor
try changing both the a & b shift solenoids
Torque converter may be the cause.
my guess would be there is a blockage in the transmission or it needs a service with new oils and filter. or you have a problem with the vacum hoses in the gear box
would you rather it shift slow????????
Yes it will... you need to switch the flywheels though to mount it to the automatic transmission...
An automatic transmission can lock in a Honda for several reasons. The most common problem is with the shift solenoids. These parts allow the transmission to shift and when one is malfunctioning the gearbox may not go into gear.
