I have a 1990 Honda Accord Ex and I am having tranny problems. I can take off and it will shift till i get to about 30 miles an hour and then it won't shift on into the next gear. I changed trannys and the tranny computer and it still does the same thing. The Sport light blinks but I can't find anything that will tell me what the codes are.

Re: 1990 Honda Accord EX Transmission
possibly due to low trans fluid pressure. the cooler in the radiator
may be plugged. to check, disconnect and bypass cooler with rubber line
& clamps. drive 2-3 miles. shifting OK now? install auxillary
cooler to bypass one in radiator. you can get one at auto-zone $30-$50.
may just need fluid & filter change, but more likely it's the
cooler. when they get plugged, either one, pressure drops alot.

i have the same car and problem and yeah its exactly that your low on tranny fluid, of course you can always pull the dipstick in the tranny with the car shut off (what my Manuel says, usually its hot and running mine says engine off) chances are your gonna be a quart low
I don't know if this will help but I 'll give you my experience .... I have a 90 accord ex 2.2 l ( love these hondas) and my s light kept flashing .... I bought a book , took it to honda of fife they said i needed a new computer 750 bucks yaeh right....... I did some tweakin under the hood and found a broken transmission solenoid sensor wire and fixed that and noticed my tranny fluid level was a quart over full, so i drained some out.... used an ohm reader and found one faulty temp sensor of 4 or 5 , changed that (the main one for the fans) anyhow I am almost certain all my troubles stemed from the computer getting the over full signal or the faulty tranny solenoid reading..... now everything is top on it .... but before the computer kept me locked out of half of my tranny, ...........
it has a problem with the second gear drum it cracks and does not fully engauge the n shifts to 3rd ..many honda owners also learn the 8 bucks a quart is the only fluid to pour in a honda..but remember 3 qaurts per drain and fill the tranny holds 7q ....it will take a case to do a drain flush...a high pressure flush will ruin a automatic tranny with alot of miles or metal deposits floating around inside..DRAIN AND FILL 3 QUARTS AT A TIME NO GASKET NEEDED ITS BUILT AND DESIGNED LIKE A MANUAL TRANNY
A green flashing "S" is similar to a check engine light. It is telling you that something in or on your transmission is not functioning correctly, such as the speed sensor or shift control solenoids. If it starts flashing and the speedometer stops working or the transmission shifts weird, take it to a mechanic.
