    Thank so much for the response. Yet, I have changed the VSS located on the rear-end, top of the differential and it improved the condition for a while ( kinda strange) and now it's back going back and forth from overdrive to 3rd..with just a little hit of the throttle..and backing off it pops back in to overdrive....doesn't know to stay put or shift. It's there another sensor I need to change???? Could the Throttle Position sensor be an issue..??? Thanks...

You need to replace either the vehicle speed sensor depending on your mountaineer it could have two, or transmission ranger sensor.

Should i drive my mercury mountaineer in over drive on or off

Depends on what you are doing...

NEVER TOW in OVERDRIVE, you will burn up the Transmisison

Under normal Driving Conditions, leave it in OD (Overdrive), the vehicle will automatically choose the gear for you

If you are driving up and down Hills (Mountains) where it is shifting back and forth a lot, my own personal preference is to take it out of OD until I am going down the hills. I hate the shifting back and forth and prefer to keep the RPM's up in the 2200 -2350 range to maximize the engine....

Ford Ranger 98'Splash don't shift 3rd and

you will need to connect it ti a scanner to confirm but it sounds like your solenoid (there is a solenoid that controls those gears inside your tranny) the part is actually cheap and should take no time to replace. the cost comes in a way of replacing the tranny fluid that will be lost.

Yes, it could very well be a bad transmission.

Automatic gears

Honda transmissions,as well as most other overdrive transmissions,should be driven at all times in drive 4,or the overdrive position,with the exception of severe driving conditions,such as towing a load,extremely hilly terrain,or long uphill grades,the trans should be taken out of overdrive,and placed in the drive 3 position.This is to prevent the perpetual shifting back and forth of the trans from 3rd into 4th,back to 3rd,back to 4th,back to 3rd,that would eventually damage both the 3rd and 4th gear clutch discs and components.
