I have a 1996 ford explorer 4.0 with automatic transmission. My o/d light flashes and when i drive on the freeway, (not all the time but most of the time), and it shifts hard into second and first when i come to a stop. The light goes out when i restart it but still shifts down hard until the next day. No problems driving in town the next day. Was told torque converter isn't locking up when freeway driving. Could the tc solenoid be bad? Never have a problem driving around town unless i drove on the freeway that day.
I did some testing after i had a diagnostic done on it and the tech said my maf was showing a high number on it. I think it was 10 when it should be 3. He said to clean it first. I did but didnt solve the problem. I hooked up a volt meter to the harness side of the maf connector and it read 5.4 volts. Isn,t it suppose to be battery voltage of 10 to 12 volts ? I still have to check the other sensors on that circuit but i wanted to get some feedback first. thank youI did some testing after i had a diagnostic done on it and the tech said my maf was showing a high number on it.

Re: I have a 1996 ford explorer 4.0 with automatic...
There are a few solinoid packs that could be faulty, your best move would be get it to a trans shop to be tested and repaired correctly. further driving will only do more damage.

your post I GUESS, means the whole car works great end to end and engine runs but the transmission fails. as most do now 1998
me playing fast and loose with century.
no miles on car told (odometer)
but most are bad this old for 100 reasons inside it
A/T boxes love to fail that is there THING.
but we check fuses.
and scan the PCM/TCM.
it must be scanned. (OBD2 tool) or as the service manual tells you you how to do that 1996 to 2000 cars some have flash codes
only for the transmission (USA car)
Gen 2 Explorer
the wiki list gen 2 boxes
as you can see there are 3 boxes used that
USA cars only
5-speed M5OD-R1 manual (4.0 L OHV)<<< NO !
5-speed M5OD-R1HD (2001-2003 Explorer Sport)
4-speed 4R55E automatic (4.0 L 1995-1996) 4-speed 4R70W automatic (V8 models) (special ratios)
5-speed 5R55E automatic (4.0 L 1997-2001)
so as you can see the engine dictates the box and not told.
and the 55E is TCM electronics controlled
same with 70w
so must be scanned or guess 100 times or more.
the overdrive light flashing on a A4Od transmission is a fault signal for the transmission , just like a ck engine light but for the transmission only , get a code read to find the fault stored in the ecm and then you'll know what exactly it is
its very common for engine swaps to have a few intermittent sensor failures on restart due to the connectors all getting maybe not all the care and protection they deserve in the swap (plastic baggies) and having a bit of dirt and corrosion in them now (spray contact cleaner)
with the od in/out/in/out an educated guess is that the engine throttle position sensor is not being read now , but a code reader will tell all
The flashing light means there is a system problem with the automatic transmission. You will probably notice a lack of power when starting from a stop with this lamp flashing. The dealer or local mechanic should be able to scan for a fault code.
It usually means the solenoid in the transmission is either bad, or sticking. Try putting in in drive and revving it a few times to see if it gets unstuck. Go down the road at about 20 mph and gas it once or twice.
The friction plates maybe well worn and need replaced. Torque converter may be failing. Automatic transmissions can and will wear out in time. 14 years is alot for any vehicle.
It's possible the light bulb has a bad filament or connection. If the transmission doesn't seem to be shifting in and out of overdrive while you're driving then chances are its the bulb or connection.
There are 5 automatic transmissions used in the Ford Ranger, Explorer and Mountaineer. They may be identified by checking the transmission code on the Safety Standard Certification Label attached to the driver's side door post, in the space marked Trans. The transmissions can also be identified by a tag attached to the lower left hand extension attaching bolt. The transmission codes are as follows:
1991–94 code T is for the A4LD transmission
1995–99 code T is for the 4R44E (2.3L, 2.5L & 3.0L) or 4R55E (4.0L) transmission
1996–99 code U is for the 4R70W (5.0L) transmission
1997–99 code D is for the 5R55E (5-speed automatic) transmission
So, what you need to do now is...establish from a FORD workshop, whether both the A4LD and 4R55E transmissions share the same components and mounting dimensions.
1996 & up are OBD2, I suggest if you are going to try to play with Transmissions , you find a good 4WD aftermarket Shop & a 4WD Forum for you Exploder. The physical fit of the Transmission may not mean it will work properly.
You need to test the selector motor at the trnasfer case, the connector might be disconnected or damaged, they had to remove this to remove the trans, so take it back to the guys (or gals) that did the work, have them check those items.
