Questions about a broken automatic transmission.

[1 fast evo 2]

I have a question about automatics and I believe some of you know a thing or to about them.

My name is Mike and I was driving the blue Talon in daily driver. The trans gave up the ghost between Dallas and Shreevport.
It had been driving comepletely normal, had ran great at the track. Then I went to leave a stop light and it free reved like a false nuetral then took off ok but in 1/2 mile it started acting wierd, dropping out of gears and then went into limp mode. Later on while doing some diagnoses behind a dairy queen I found that there was no fluid flow out the cooler lines.
We finally got the trans out of the car last week and found that the stator was broken in the torque converter also the pump in the trans was kinda scarfed up but not broken(looks like it should still pump oil).

Now I don't know jack about an auto so my question is can a broken stator cause there to be no fluid flow out of the cooler lines or did the pump just suddenly out of no where loose pressure?

Thanks for any help

I'll take a guess at this, but I am a more of a tractor mechanic when it comes to transmissions. The cooler flow is not under system pressure so just checking the flow there does not mean the pump is not working. It just means the flow and/or pressure is low enough that non is being diverted to the cooler. The free wheel then moving then dropping out of gear was just the catching and releasing of the stator. Does anything else look toasted?
Good luck, I'll be diving into mine this winter.

Thanks for the reply.
The end clutch or od is a little worn, that I am assuming is from pulling that large trailer with a small car at high speeds(wont be doing that again). The 1st gear clutch pack is pretty much toast, that I am assuming was from trying to limp the car and trailer back to town( if I let it sit for a minute then revved the snot out of it it would moved forward for a short distance).

wild guess....the converter went bad, then it damaged the pump, and the low line pressure could not apply the clutch firmly enough, so it fried.

im with squirrel on this one...make her bullet proof for next year,and cruise with us slowpokes.lol

Number 1 thing I would have checked the fluid level...
that would cause the initial problems and that slamming
will bust the sprag... also most trans wont move fluid
in park(mopars dont for sure) so it wouldnt come out
the cooler line

Mr P body, his car is more Mitsubishi than Dodge. Sounds like converter Failure is where it started. Did you check flow to the cooler in all gears or just Park?

You said it was driving normal! You ran me off the road with your trailer on the way to Texas. I don't call that normal.

Thanks for the replys.
I didn't check for fluid flow in other gears.
I did check the fluid level and it was full ( it didnt slam into gear from the false nuetral, was just a slight nothing and then it was in gear).
Slow pokes rule.
Next year I will either have no trailer or a very small and light trailer.

BigG- sorry about that but I was trying to keep up with the maniacs I was following(which I am assuming partially led to the trans failure) I later went off by myself until I hooked up with Moparman63 and his buddies for a much more relaxed cruise.
The car will hopefully be back together this week, then maybe head to the track for some passes(that's the plan anyway, I hope the weather permits).
P.S.-BigG I believe I was the one off the road when I passed you.

Well that was partially my fault. Once again sorry.

Mike I had a simular issue with low fluid and the whole f'king tranny was toast. Glad to hear you'll be on the road again quickly.

I'm leaning towards the opinions about too low a fluid level being the start to the problems.

Funny now thinking back, It just would have not made sense if I said you ran me on the road? No big deal, I am still alive.
