Hello! Im despite and have a 1993 Honda Accord LX loll, I been trying and trying and trying to figure this out. I have had a few things come up with codes to replace such as my transmission solenoids, TPS and harness, VSS, an even a TCU rebuild jus to bee safe and everything got better an better till it seems to bee my last problem which its seems to not bee shifting out second or first unless I'm really heavy foot/jus high rpms. If I'm jus chilling at low rpms it's jus doesn't seem like to shift. I do still have a code on my D4 still for a code 10 which is my coolant temp shorted or open but I'm waiting on the harness. And even then can that cause the issue? If not what else is it? I put a lot of money and time into this and really trying to fix this.
