Heres the deal. My 5.0 is finally up and running again. Got the distributor set right and everything else.
My problem now is this. Its an AOD tranny, and when I put it in D and start to accelerate it will not go above 2000rpms w/o shifting into 2nd. It then skips 2nd and goes straight to 3rd where it starts to act fine. It even does this when I floor it. Revs climb to ~2000, drop to 1500, flicker to around 1600 as it shifts into 3rd then acts fine. The problem is my acceleration SUCKS, until I hit around 45-50. I then start to pull damn nicely since the intake upgrade. Also at any mph, I can mat the gas and it will not gear down. it just slowly climbs until its in the correct power band to start accelerating. If I shift it manually there is no problem. I can stick it in 1st, rev it to whatever I want, and shift to D. It is hardly in 2nd any that way, but it was always like that before.
Finally, if Im on the hw and have the car in OD, any press of the gas causes it to act like its "slipping." The revs climb like I have a clutch pressed in. It doesnt grab doing that, and I have to let off the gas to let the revs fall then it grabs at whatever mph I was at. As long as I barely put in the gas it will accelerate in OD, any effort on the pedal causes it to "slip" and rev up.
Is my torque converter shot? Im not used to auto problems. I always just stuck it in D and had at it. This is the first time in 7 years Ive had trouble with the stock tranny.
The only mods to the car are...
K&N 9" conical filter, underdrive pulleys, msd dist cap/rotor/coil, and a Cobra upper/lower intake. A full exhaust is going on it Sat, but Id like to know whats causing the tranny to act like this.
Any help is appreciated!

Sounds more like a valvebody problem but thats just a guess. Also did you just reinstall the trans when you got the motor in? Is the torque converter seated all the way in? It takes several turns and clicks to make sure all the input splines are lined up. Is the cabel connected at the throttle body? If you've still got the stock plastic grommet on there, they do break quite often and cause the trans to act up like you described.
Whatever you do, don't drive it any more. You are probably burning up all theinternals inside the tranny. Get it somewhere and let an expert look at it.

I agree, doesnt sound like a torque converter problem, I just started learning automatic trannies in school and i was surprised theyre very complex looking but once you get to know the components theyre pretty easy. I dont know about the Ford AOD yet but sounds like a band not grabbing all the way or maybe a governor problem, idk. Im just giving out ideas though, have a professional check it out.

You are having a bad case of the AOD - you just described all the major fallbacks of the STOCK AOD. If 4th slips, the OD band is fried or the presure to the OD servo is weak - either way it will now require a rebuild - or at least some service to the internals. Get a shift kit from Baumann to solve your shift problems. It will allow you to firm teh shifts to your desire and also extend the shift points.

I reconnected all the TV linkage, and all. I had to go to ford for a new one of those gromments since mine crumbled taking it apart. I know I reconnected it, could it need adjusting?

If for some reason it was the TV linkage would that nuke my tranny and be cause for a rebuild or a new one? Would it be as easy as just reconnecting it? Im sure it wouldnt be lol.

NOPE.


you need to add some tension, or have a tranny shop set it right.

Alright, thanks man.

Its going to the shop Sat or Mon for a full exhaust setup, so Ill have them adjust that as well. Hopefully thats all it is, and it just needs some tension added. It ran great before the intake install. I dont know how it sitting would cause the tranny to grenade, so heres to hoping some tension is all thats needed

I checked the TV linkage last night, and it had come undone for some reason. I plugged it back in and its a bit loose in the grommet but the car shifts like it should now. Im going to try and tighten it up some more over the weekend.
