Trans only goes in to gear below 1000 rpm

[volks14]

Just bought a 92 explorer,its kinda got a weird issue.I start it and have to let it idle down below probably 900 rpm and then shift it dirrectly to 1 2 or drive to get it in to gear,If i shift it above such rpm or into overdrive it makes a whinning noise and goes no where and has no gears........but on repeating the 900 rpm or below it slides right into gear....When in gear it doesnt slip or cause any grief,any idea what this might be?Also overdrive works after I get up to 50 mph weird stuff?

Welcome to this forum! Connect a 0 - 300 PSI test gauge onto the rear service port to check the pressure in each gear setting. How many miles does it have? Did you check the fluid level? Was the filter ever replaced? Does this only happen when it's cold?

It happens all the time cold or hot,has 303000km on it and I bought the thing for 200 bucks so I would imagine the filter has not been changed though the fluid does appear to be good in color.And when in gear it climbs like a billy goat no slipping whatsoever

Transmission Troubleshooting Step 1: Fluid level. I know it's such a beginner type thing but that's exactly why it gets overlooked. I've seen so many trans "holy-****" moments boil down to low fluid. Also keep in mind that on an older one like this, it's possible the trans has been changed or worked on. This opens you up to the chance of an incorrect dipstick length. Don't know about this model/year. But some vehicles have had different length dipsticks depending on year but the same transmissions. (pan depth, tube length, etc). Which can give you an incorrect measurement. Just something simple to think about. Best of luck.

OD does not work below 50 mile per hour, this is normal they are made that way.
