Really?

Come now children, let us sit together and listen to the stories the old timer brings...

Please.. tell us more old timer

 

so can I just replace the pump or is the whole damn tranny going to need rebuilt? Also how can I tell for sure if it is the pump when I drop the tranny?

 

Always a young whiper snapper smart alek around huh? ...

 

If nothing else is damaged (you did not burn any clutches) al you need is a pump change and you "should" be fine as long as pump did not trash out and send metal filings through tranny.

 

now can I rebuild the pump or do I have to get a whole new unit? also how much am I looking at for parts?

 

Yeah, little more info if possible. Was the 'verter too far away causing the non pumping action, or was it too close initially. If it was the second, why did it just occur after he put the washers in, conincedence?

Thanks,
Andrew

 

that is the same question I have. It worked fine when the verter was against the fly wheel, but due to a few threads I read and on the manf web site I shimmed it as recommended.

 

The converter is driven by the outer flange on the torque converter that engages a "cog" on the pump. It appears that when he shimed it the it pushed the flange in far enough to put too much pressure on input cog/flange and cause the pump to fail.

 

There is no cog in a 4L60-E front pump, there is a vane rotor. There is no flange, there is a pair of raised keys that engage notches on the hub of the torque converter. 4L60-E's do not have a 3.09:1 first gear, they have a 3.059:1 first gear, 1.625:1 second gear, and a 0.696:1 fourth gear. "Second" is really overdriven first, "third" is really direct, and "fourth" is really overdrive. Try to be less incorrect. Misinformation is the MOTHER of all failure.

 

possibly what happened is when the converter was shimmed, it was pushed into the pump. The pump ring is actually plastic, and could have broken. It also could have pushed those vanes into the backside of the pump and caused them to score which would result in lose of pressure. There's a lot that could have gone wrong there.

Try and stay with me here ....



See the thing that looks like it would belong in an electric motor? That's the pump. The metal tabs you see laying done go in the gaps of that little electric motor armature looking thing. See the ears on the rotor? That's what the converter locks into. Those could have even broken.

snoman, this isn't old skewl trannies. Times have changed, keep up or stay home on the porch. Regardless, know your stuff before you try and start informing people. James is right, mis-informing people will do more harm than help even though it has good intentions. As my grandfather used to say ... the road to hell is paved with good intentions.
