1987 legend transmission problem

[curly bo]

I have a 1987 legend LS with automatic transmission that does`t shift up from first gear. When i select third or fourth on shifter it starts off in first gear as it should, but won`t shift up. When i select second gear ( the lowest option on selector) it will drive in second gear as it should. I don`t think the shift linkage is the problem. Is there anything i can do besides changing tranny`s

Doesn't sound all that good the lack of response to curly bo's auto transmission troubles back on 06-18-2008.
Hmmm, my car just started these symptoms just today but was fine yesterday and ECU only flashes an oxygen sensor trouble code.
Possibly anyone have an idea?

How does one troubleshoot something like this?
Thanks!

The shift problem comes from the transmission solenoids failing. Sometimes removing and cleaning them will solve the problem. The car should have two sets of them. I think the one you are having problem with is the pair that is mounted lowest. Removal involves removing air filter housing and some surrounding fittings to get to them. Then unplug harness and remove two or three bolts and carefully slide them off so as not to damage the gaskets or the two small dime size screens that filter the fluid. Clean them by spraying carb or brake cleaner. Also you can test for function by grounding them and applying 12 volts. You will hear a solid click if functioning properly. No click, no upshift. Hope this helps.
