Tranny wont stay in OD
Hello, I have a '92 Honda Accord EX 4cy. with 4 speed automatic. When it shifts into OD it keeps shifting between 3rd and OD(back and forth constantly). It will stay in OD for a few seconds and then fall out and back up again. What is wrong? Is this a major tranny problem? I'm not a Honda guy so I'm totally unfamiliar with them.

Re: Tranny wont stay in OD
I'll take a swing.
1) Trans fluid level is? Fluid condidtion is?
2) Throttle control cable is properly adjusted?
3) Test and clean the locak up solenoid
EDIT: Dang it, first question should have been.....Any stored codes in the ECU/TCU?

Are you sure it’s dropping into third gear and you’re not feeling the torque converter lock dropping out?
If it’s the torque converter lockup the RPM will shoot up a few hundred 200-300.
I would check the following:
Make sure the engine is running the proper factory temp when warm. (If the engine temp is too low torque converter lock will always keep dropping in and out.)
Check the connector for the top solenoid for corrosion and OHM check the solenoid.
OHM check the front NC sensor on the right side of the trans as shown in this link. This sensor should also be removed and cleaned.
