87 Prelude tranny problem

I've replace the throttle body on the prelude (2.0 Si 4WS) Made a lot of
diff.it works and goes!!!! much better but now tranny shifting stuffed.(Very
very late changes)Any ideas ?????? please.(timing is OK,tranny cable
adjusted again)

 

Sounds like you still need to adjust the trans throttle valve cable. Late
shift usually means the cable is too tight. Good luck. Scott

 

Tx Scott,well it turned out to be the WRONG bloody TB (apperently it was out
of "imported wreck") and TPS was the culprit,so replaced it with the
original one BUT this time i'd made sure i put the vacum hoses RIGHT way
around ..Its OK now,actually like new.Tx again mate.Steve

ps.According to my tranny mechanic the cable SHOULD be very tight(which he
did) it changes very nice'n smooth now.

 

Two thoughts, one easy to check and the other not so easy:

The tranny cable may be hanging up. With the engine off, the cable should
maintain tension at the throttle body as you open and close the throttle. If
it is hanging, graphite (I like Lock Ease, graphite in kerosene carrier)
squirted inside the cable housing is the ticket.

Anything that reduces engine performance will cause the throttle to be open
farther than "normal" and make the tranny behave as though the cable is too
tight... late shifts. If the response feels good now this probably isn't
your problem, though.
