tranny issue need help

Two weeks ago i installed a low milage tranny in my brothers 97 bird. Everything was fine till tonight. Suddenly tonight the car became very difficult to drive. very hard to get to accelerate from a stop. when you step on the gas it bogs down. Once you get it going it drives sorta ok. We drove it on the highway. the car really was not much good in "D", but when we left it in "2" it would maintain 55mph at 4000 rpm.
Even when the car was in park when we try to rev it up it acts like the engine is under load. I cleaned the MAF, no difference.
The green "o/d" light started blinking tonight when all this came on. Otherwise the car was running nicely for over a week up till tonight. Any input i can get is appreciated.
Thanks!
Gordon

Have the trans. codes scanned??? The blinking OD light is it's way of saying "Hey, something is wrong". The only thing that comes to mind is bad or mis-alinged MLPS, but I don't know if that would cause that issue or not.

These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

I got under the car to check it all out. The main connector that leads from the car to tranny harness was rather dirty. I cleaned all the contacts real well, and made sure the connector was securely fastened. Now it drives 100% better. Though the blinking trans light is still flashing. I'm assuming at this point that it still remembers the code from the eariler problem as i havent disconnected the battery.

Gordon,

What year tranny did you install? Did the harness need to be repinned? Just a thought.

It's not a 97 Sport, it just looks like one!

If the blinking light has been an issue since the swap then you may indeed have something wired wrong.

Its a 97 trans, so there was no need to repin anything. There wasnt a blinking light at all until last night. Been driving the car over a week. It only came on when the car started driving crappy.

I got under there last night and cleaned the main harness connector for the transmission real well. That seemed to solve the issue. I did notice that the wiring that is attached to the connector on the vehicle side looks a bit worn. the insulation is frayed in several places. Does anyone know if that harness for the tranny that comes from the car can easily be replaced? Is there another connector under the carpet somewhere? Or is it completly wired to the main wiring harness.

Thanks for all the help so far guys!

Here's an update for anyone interested. The car seems to run fine, but after he drives awhile and it gets warmed up the symptoms sometimes return. LEt it cool off and its fine again.

Thoughts??

I am going to guess MLPS, but I would get the codes read first. If the O/D light is blinking, then it is throwing a tranny code and that will probably diagnose your problem. The other option may be a bad shift solenoid, but I don't think I quite understand what is meant by not running right? Is it missing, etc.?

Currently In the Short Bus Garage:

1 - '97 F150 XLT 4x4 Flareside, 4.6L (130,000+ miles) - Currently being dismantled and rebuilt with upgrades!
1 - '00 Mustang GT (likes to accelerate with the brake on!), 4.6L (60,000+ miles - only comes out when I need to get somewhere fast.)

oh yeah, and they all have 4R70W's

As far as "not running right" goes let me describe it like this. The car was running basically perfectly. Then without any warning it started to run as if it had no power, or more accuratly like the car was under load. When the symptoms are occuring it dosent sound good revving it up even when its in park. It revs up like its in gear (but its not). Then if you take it for a drive and get it moving it feels alright until you get to needing more than 2nd gear. We drove it on the highway and at 55mph it was revving at about 4000 rpm. Then i parked it, let it cool down cleaned the wiring connector that goes to the tranny. Then suddenly it ran fine. The symptoms have returned and gone away a couple of times. It seems like it does it when the car gets warm(sometimes). When it does the check engine light, the tranny light, and the low coolant light all came on. So I'm not sure what exactly to make of it.

Dude....

It gave a code with the flashing OD light. No need to have the internet guessing going on or keep messing with wiring and stuff, you have the means to actually very likely know what is wrong. Get the code scanned.

I mean, that is exactly what it's there for and it is flashing at you trying to get your attention to let you know that it knows what you need to know.

Or you can go on chasing it the hard way. I wouldn't, but it isn't up to me.

Sorry Darrin,
Not trying to waste anyones time. Not mine the internets or anyone on here. My last post asking a question was like 6 days ago. Wether asked what i meant by "not running right". He took the time to respond to the thread, so i followed up with more detail. Thats all.
The hard part right now is that i dont own nor drive this car. I havent touched it or worked on it since the original post. I've been trying to get my brother to go get the code read. Which is a bit harder than it might seem.
Soon as i know what codes it pulls, hopefully the solution will present itself.

Thanks to you and everyone who has offered advice or suggestions.

No, no, no..

I wasn't meaning that you were wasting anyone else's time. I meant why waste your time guessing when you have the means to an answer is all.

Did you see the movie Bruce Almighty and see the part where he was asking for a sign? This brought to mind that.

That's why I posted. LOL

I gotcha Darrin. No worries. I wasnt freaking out on you there.

So yesterday i got my brother to get the codes read. Currently the o/d light isnt blinking. The only code it read was a camshaft position sensor...so who knows, ghosts i guess. maybe badgers..

Nope, insufficient equipment. LOL

He went to Autozone or something like that to get it done didn't he? Either that or a generic universal coed reader like an Actron cheapie was used.

The transmission codes take a better scanner to get to.

I had a feeling that might be the case. It was an autozone. I need to find a real deal scanner.
