I was cruising at about 50 mph this morning and all the sudden out of no where my car will not move in any gear. It has just been rebuilt about 2,000 miles ago with a brand new art carr convertor (junk). Any ideas of what has happened? It quit locking up yesterday afternoon as well and then it just quit. Maybe the pump?

did you hear any noises before it quit.

Ok first lets see if its the pump disconect one of the cooler lines at the radiator put a drain pan down and start the vehicle it should spray a significant amount of fluid in a very short time , If it sprays none out then its the pump , If it sprays alot I would then remove the trans and though rare inspect the converter input splines to see it they are stripped

Yes i heard a some small clank around like maybe the size of some small ball bearings banging around for a breif second before it went.

And performabuilt i appreciate the advice i do need to do that but i need to get it off the side of the road first so i can check that. lol Thanks a lot for the info!

luckily i got access to a truck and car trailer though!

If it was the pump would i of heard a noise when it went like the clanking around in the tranny?

Not nessesarily if the rotor just split it could be quite sudden and make no noise at all

i have always associated a pump failure with some kind of whining noise. of course i'm not saying that the pump will definetely whine if it's low on fluid or failing, but i've seen several that did. since you heard a noise like ball bearings breaking i would have to assume something broke. problem is it could be in the converter or internal. might need to plan on making a trip back to your trans mechanic

01'WS6

I appreciate your info as well. And the trip back to the trans mechanic is already in order. Kinda hoping its the convertor though! And i never did hear any whining.

I figure he will have to do that anyway it works out was just giving him something to check ,As for noise sometimes they do and sometimes they dont

hoover112

yeah the instructions for checking pump flow are ok if you want to verify flow. i have a feeling he dont have a pump problem though. i also cannot imagine any hard part that would cause a complete loss of pull in forward or reverse, that would have caused it to loose lockup the day before except for the input shaft. even then i dont see it breaking while cruising at 50mph. i'd like to hear what ends up being wrong with it just for future knowledge.

01'WS6

I will definately follow up on it once its torn down and we find the culprit. And im sure i was "cruising" 50 and not beating on it because my cruise control was on.

Well its also possible they are unrelated issues , Or possibly the converter clutch came apart and stopped the filter up and resulted in pump failure , Im curious my self to see what it is

01'WS6

The pump ended up locking up and broke the shaft off the convertor for those who wanted to know.

Do you mean it broke the stator in the pump off the outer shaft that goes into the converter?

01'WS6

U got me there! lol I dont have a clue. It was broke at the end of the convertor shaft (the only one that i know of that comes out of it) and the pump was in a few pieces. Sorry i dont have a clue when it comes to an automatic transmission or any transmission as far as its concerend! lol

can you take a picture of the broken stuff would be cool to see

Who's TC were you using when it broke? I have seen some lower budget converter hubs break do to improper hardening. Just a little FYI.

Just curious... With the pump dissasembled does it appear to have lost lube? Meaning is it severely scored and discolored or not? Pumps usually do not lock up at cruising speeds under a light load with cruise on... usually start up, hard launches or when towing heavy loads.

It is possible the converter hub failed and took out the pump... that makes more sense to me... probably happened during a PWM event or at 100% lock-up.

I am sure the folks making the repairs will thoroughly inspect it for residual debris. Sounds like you are in good hands indeed.

of interest all our units have pwm disabled regardless of pcm setting
