95 ford aod shift problem
My 95 ford has been sitting up for a couple of months. when I started it the other day,it had a shift problem. It has never done that in the past when I drove it all the time. I had a mechanic install a new oil pump as it was running lower pressure before I parked it. Could it be something he left off? Maybe need fresh fluid or low fluid? Help me out guys. I don't drive it anymore and need to sell it!!
Thanks

What might the symtoms be? And when does it happen.
Yes some fresh fluid and additive may help. The e4od is electronic so check all connections. If it act like goes into neutral while driving the MPLS or shift position sensor may be bad, give us little info . Thanks

not real sure. I had been having a oil pressure problem. the guy working on it installed a new pump. I wonder if he did not install the tranny back right. I am assuming he moved the tranny since that is one posibility. it started happening when I cranked it up and put it in drive and hesitated to go in gear. it went in gear and hesitates to change gears. When it lugs, it goes into netural then back in gear. I thought when I first cranked it up, that the conveter drained into the pan. any ideas???

From my limited experience in troubleshooting automatic transmissions, I would venture to guess it may be low on fluid, or possibly have something misaligned. I'm not sure how the electronic one operates for shiftpoints, but on some of the Ford Taurus cars they start slipping like that from internal issues. Typically on those, they need a rebuild.
On an AOD like that, especially an electronic one, it may just be a bad sensor inside. First thing, check the fluid. Is it full? Is the fluid in decent condition? (Pinkish red, not orange or brown, doesn't smell burnt, no metallic floaty bits, etc.). After that, check ALL the electrical connections that go to and from the transmission. If something wiggled loose, it would wreak all sorts of havoc.
Aside from that, without seeing it for myself, I'm out of ideas.

My 94 did that, new filter and fluid fixed it right up, now it jumps right into gear again.
I doubt he would have taken the tranny away from the motor to chance the oil pump, no reason to.

Fluid/filter change is really just a good idea anyway. Especially if it fixes your problem. One thing I just thought of, on a LOT of overdrive transmissions, the T.V. "kickdown" cable *ABSOLUTELY* has to be adjusted properly. Otherwise it will do all kinds of wierd things. Check that too. If you had the oil pump replaced, they most likely removed the intake (and all the linkages) to get at it.

I must admit I got a little lax with the trans, have the oil changed like clockwork on em but didn't do the trans since just after I bought it about 6 years ago now.
So naturally that was the first thing I thought of when I started noticing it wouldn't go into gear like it should.
I know, my bad.....
Never happen again!

Transmissions are sadly one of the most overlooked parts of a vehicle. Most people never think to even check their fluid level in an automatic. I'm guilty of this myself, and I'm trying to break myself of that habit.
The other thing is the gear oil in the axles. Nobody ever checks those anymore. No one thinks of tranny fluid or axle grease until there's a problem, and usually by then it's too late.

Oh, I will agree there.
My '90 IROC-Z wound up needing a new tranny at 200,000 miles because I never changed the filter/fluid in it. When I first took the pan off, it had an inch of metallic sludge in the bottom of the pan. Surprisingly, it still worked ok, but slipped when going from 1st to 2nd.
My '63 C-10 needed it's 3 speed auto replaced a few years ago due to me never checking the fluid, and it ran so low it eventually burnt out the 3rd gear clutch pack. I had 1st and 2nd, but no 3rd at all.
Now I try to monitor my fluid in my automatics every time I check my oil. Figure it's a good habit to get into.
Step 1. Check oil.
Step 2. Start vehicle.
Step 3. Shift into all gears.
Step 4. Check tranny fluid.
Step 5. ???
Step 6. Profit!
Fortunately, I only own one vehicle now that has an auto tranny. It's a C6, so I don't worry about it nearly as much as I did in my Mercury with the AOD.
