Okay, so I replaced the shift solenoids because there seemed to be a problem with one of them. The car works fine for about an hour, then starts acting up again. I.e., it won't shift into second unless I lift off the throttle at the shift point. In the meantime, that silly danged gear on the instrument cluster keeps flashing at me.

Soooo......

I take it to a transmission shop to have them run the transmission trouble codes. The guy takes her out for a spin and gets the following codes:

P0712 TRANSFLUID TEMP SENSOR LOW INPUT
P0713 TRANS FLUID TEMP SENSOR HIGH INPUT
P1715 SHIFT SOLENOID 2 FAULT
P0755 SHIFT SOLENOID B FAULT
P0758 SHIFT SOLENOID B ELECTRICAL
P0733 GEAR THREE INCORRECT RATIO

He then cleared the codes and drove it back to the shop. On the return drive it worked fine, so I drove it home. The one thing I noticed was that immeiately after putting the car into motion after startup the gear light flashed, but quit after shifting. The car worked fine the rest of the day, so I thought the problem was fixed.

The next day, the problem returned: Revving at the 1-2 shift point, and no shift unless I lifted the throttle. :angry: That was Friday.

On Saturday my wife had to drive about forty miles (one way), so I drove for her, and we took the Taurus. I wanted to see what the car would do on a longer trip, especially with the stop-and-go traffic we'd be in. I was also hoping to be blessed by some automotive god and the problem would go away again.

No such luck. :angryfire:

However, by the time we got where we were going, I got to thinking about that P0758 code. It occurred to me that the transmission was suffering from a bad connection. Since that white plug on top of the tranny seems to be the one that feeds power to the shift solenoids (among other things), I decided to unplug and inspect it. It looked a bit grungy and the pins looked grungy. So, I wiped off the female side of the plug and plugged it back in.

It has worked fine, for the most part, ever since. I can't decide whether to be happy that it's working or mad because I apparently wasted about $70.00 on those three solenoids. The only problem I still have is the gear light flashes the first two times it shifts from a dead stop, and the 1-2 and 2-3 shifts sometimes feel a bit slushy.

Call me old-fashioned, but I am not at all convinced that electronic controls belong on an automatic transmission. Wires and hydraulic fluid just don't go together, IMHO.

By the way: The odometer hit 200,000 miles on Saturday. We've driven the heck out of that Taurus!

Your old fashioned.. we don't have much electronic problems witht he transmissions.. problems are almost always mechanical. I think I have only replaced a couple of solenoids on a AX4 trans in 10 plus years of working on fords. And I can't even remember a internal wiring problem on one.

Most common ax problems i see now are torque converter splines striping, pump shafts breaking and pumps breaking.

I love my MTX.....

As for problems.. all of mine are on my AX4N. And they are usually compound problems. AKA. More expensive.

i KNOW this is an old thread!! my question is to Grover: do you still have "Carmen" ?? and, most importantly-if you still have her, how is the trans holding up ?? good job on finding the bad connection, now if only i could be so lucky,,,,
