YACT: Transmission ... strange problem

I have a weird problem with my automatic transmission in my Ford Mustang 1993 LX.

When I start the car (after it was standing for some time) the transmission has problems smoothly transitioning into 1st gear (and also sometimes) 2nd gear.
It just doesn't shift until suddenly it does and the car lurches forward.
 
when you say it was "standing" meaning it wasn't driven for a long time, or you just had it in park for a while, but the engine on?
Well either way, you prob want to change the tranny fluid and see if it is any better.

i wouldn't change the tranny fluid yet. that tends to break up a lot of fine particles that are in the trans, and they can get lodged in the gears after the new fluid is put in. This happened to me in my old trans am. A shop changed the trans fluid at about 100k miles and boom, 200 miles later the trans went.
 
well a 93 is going to be up there in miles and you need to change the trans fluid every once in a while. It looses it's viscosity after time and needs to be replaced. There's no other way to fix it with out draining it in the 1st place.

The V6 AOD is not the same as the V8 AOD's. There are all kinds of variations.

The current AOD-EW is a pretty good transmission. Nicely reliable.

The 5.0L uses the AODE and the 3.8L uses the A4LD.

I need to know if this happens when the tranmsisson is cold, warm, or both. I would also like to know what you mean by "after it was standing for some time", do you mean not driven for a few hours or days, or do you mean after it has been idling for a while?
 
After it was parked for some time. Although it also happens after driving for a couple of minutes. Have not done any long drives yet with this problem ...


I think I will try replacing the trany fluid.
Shouldn't be too hard to do that myself, would it?

depends on whther or not you have a transmission drain plug. Drain and refill shouldn't be all too hard. If you want to replace the filter, then it gets a bit more involced. you'll need about 6 qts for the ford? (i don't know too much bout domestics, sorry, maybe quix can help ya better)

Might also want to think about replacing the rear differential fluid while you have the car up for the transmission, though I'm not sure if the rear diff has a drain plug either. When you do the rear diff, make sure you can get the fill plug off before you take off the drain plug; if you take off the drain plug first, and then find that the fill plug is stuck, how are you gonna fill 'er back up?
 
My Crown Vic has an AOD....it delays shifts then slams the next gear with a neck snap unless you're on it hard...who knows why. Now the front seal is spewing fluid. Love the car though 🙁

I think the new trans needs a shift kit so it doesnt eat itself to death.
 
It sounds like you have a cold transmission shifting concern. Worn clutch pack seals allowing excessive fluid to by-pass the clutch packs and not allowing them to engage the drive drum usually cause this type of concern. There is no simple fix for this concern, but it couldn?t hurt to replace the fluid if you feel up to the task. I usually don?t recommend fluid additives because they can cause more harm than good, but in your case it might be worth a try to prolong the inevitable transmission repair or replacement.

Here is a link to the repair procedure and to an additive that I prefer to use occasionally.

I also recommend sticking with Mercon or Dexron III transmission fluid. Any synthetic or synthetic blend would worst the condition that your are experiencing because they flow better than normal fluid.
