The KM177-6 (also known as F4A23)is a four-speed electronic automatic transaxle built by Mitsubishi and was used in all TP models and carburetor Second Generation models.

it is normal for a first gen auto to lurch into first at the lights as you slow down

clunks are not normal

tranny oil thinning or clogged filter = a service may lessen the clunk
could be diff back lash
worn CV joints
saggy /broken front and rear mounts
that little shock out of gas (now only found as a second gen V6 auto shock near its rear mount )
worn kickdown band (internal )
or faulty kick down solenoid


Check the single wire going into the solenoid on the front of the Auto
it frays/cracks because of the heat and movement over the years

the solenoid is part of the round cap held in with a large circlip

you take the circlip and plate off to do the adjustment
