Automatic won`t change above second gear

automatic or manual ?
if not a linkage or adjustment needed
auto
=probably a shift solenoid problem
get to the solenoids with the pan off

manual =syncro

check the linkages from gear stick to gearbox may be loose.

may hav burn a shift solenoid--put car on a scanner--local parts place does it for free--nomerical codes will show and explained in a manual--but bfore replacin a part a more detailed scan shud b performed

Check your ignition coils. One of mine was bad and when I replaced it, the shifting issue stopped.

got a lot of miles on it???? might need syncros

Most likely the second gear section of the transmission has gone bad. There are 3 or 4 different gear sections or assemblies in an automatic transmission, when they go bad, they go bad.

What you need to check is the transmission release bearing because if there is a clearance on the release bearing you will encounter this problem and also check the transmission oil.

do not flush the trans, that will make it worse.
My friend you have no second gear, you need trans rebuilt.
If you flush it now you can cause more damage.

sounds like the selector box at fault but change the auto oil and filter with some treatment and this should solve youre problem

you need to replace clutch pack for that gear can be ordered seperately from parts store or dealer if you want to save money call peach street auto recycling at 1800-365-2341 for a warrantied used one! also might be time for change trans filter and fluid filter could be slightly clogged but I lean towards clutch pack I replace these alot on Hondas
