Hi Guys,
This question isnt psd related its about my 2000 ranger. I didnt get much response over in the ranger forums so id firgure id ask you guys. A few weeks ago I was driving along and out of no where I lost drive. When I tried to accelerate it had nothing, just squealed in drive. Soon after the squealing stopped. I scanned it and came up with nothing. Oh, and reverse works fine. It has a 4R44E auto 4x4.

Any help would be great before I go and order a new tranny for it.
Thanks.
Steve

 

sounds like something broke


im no transmission expert

 

Yeah something broke for sure. Im just trying to find out if I can fix it or not. I know nothing about the inner workings of a transmission.

me eather the furthest iv gone into a transmison is swaping out entire units and fluid and fliters and pans

 

If it didn't slip before I would say the valve body crapped out on ya. My .02 'cause I am no expert. You may need a whole new tranny. Good luck.

 

It's time to change fluid and have a look around. If you find dark oil (smells burnt) and "junk" inside that's bad news. If you find metal shavings, um, that's even worse.

Usually when one hears a "whining" noise the first thing I suspect is the front pump, and when it goes, it usually showers the internals with metal shavings. Steel from the pump circulating in ATF acts much like a fragmentary grenade destroying everything inside an automatic transmission.

 

does it go foward in manual low?

 

What about the torque converter clutches? Could they be shot?

 

We have an ex-Ford tranny expert, engineer on the forum perhaps he'll jump in and give you some guidance.

Sure they could. But that won't cause the problem you're having.

Since it moves in reverse the torque converter is fine. Your problem is a mcechanical breakage inside the trans. If I had to guess I'd say it is the forward clutch, but without taking it apart I can't be sure.

Don't bother changing the fluid. At this point that's a waste of money. That trans has to come out and be rebuilt or replaced.

 

Thanks for the advice guys. Im going to order a replacement for it today.
