1993 Accord Taking Forever to go into Lockup

I have a 1993 Honda Accord LX and it takes it forever to go into lockup. 15 miles or more. When the transmission is finally hot enough it will go into lock up all day long. I've changed the transmission fluid twice with Honda fluid. I don't know what could be wrong. Thanks.

Nothing wrong with that ... it has to get to a certain temperature before it will go into lockup.

My accord 91 does the same, I just clean the fast idle thermo valve and the car it's fine know, hope this help.

Where is this valve located?

what is lock up?

Have you considered replacing the thermostat. My 91 was having the same problem, but i noticed on colder days the temp guage registered near cold. I replaced thermostat and it locks up as soon as i get on highway. Was running about 3400 rpm at 70 mph....now i run 3000 rpm at 70 mph. Saves on the gas bill. 3 more miles to the gallon highway. $3 part plus gasket and 30 mins of work. Worth a shot.

Thats probably what it is... I was having problems with my 91 going into lockup. When I went to change the thermostat It wasn't even there LOL. I put a new one in and it goes into lockup with out any problem now.
