I have a 99 honda accord 4dr. I changed the header and exhaust system on the car. I changed the transmission not to long ago would say 3 months ago. Everytime the car shift it takes long to change gear, you could hear it change gear loud. Dont know poeple have told me to change the solinoid on the transmission. I changed the one that goes underneath the battery. Should i change other one or is it something different?
