Bent torque converter snap ring

[CNY_Dave]

OK, I have my boneyard trans, they pulled the torque converter and so I looked at how to put it back in.

 

It looks like you slide the tube that drives the pump all the way off and out, then insert that into the torque converter, get the snap ring settled into place, then slide the whole kit-n-kaboodle into the trans.

 

Looks like they munged the snap-ring, though, is that common or indicative of a heavy-handed disassembly?

 

Should I get a new ring or straighten it?

 

Is the snap ring really required?

 

I don't want to get this thing in and then find out they broke the pump- any way to feel for it being 'right' after getting the TC back in?

yes you need it and yes you can straiten it it holds the pump extention to the converter if not there the slip ring can move in its bore

[Gloyale]

I'd get a new one.

 

You can straighten it, if the ends are not ground off.

 

It needs to hold the extension tube securely to the TC during assembly.

 

Once assembled, there is no load on it, so it just needs to fit well engouh to keep the extension tight on the TC during seating.

 

Fully seated, the lip of the TC should barely protrude beyond the edge of the bellhousing. less than 5mm.

I've seen them be a little wonky and not want to stay in place well on a bench before too so I'm not too concerned by the pictures.

 

New snap ring sounds like the way to go but I've installed some "loose" ones before I didn't like simply because that's how they were and the trans was running fine...always on older stuff.

 

I have a torque converter for an H6 lying in my garage, i could send you the snap ring if it's on there.

 

There's a ring seal on the shaft too, sits in a groove at least on the older 4EATs...I can't recall if my H6 had one or not when I replaced it, might want to get that or make sure it's in place. that can get tweaked and not want to ride tight on the shaft as well. Dealer only on both of those I imagine.

[CNY_Dave]

The dealer 'should' have a new snap ring, and TC seal, and driveshaft seal, and filters by Friday, when I'll need them.

 

I didn't see any kind of a seal inside the TC, or inside the trans, other than the seal for the converter itself, but that doesn't mean it's not there.

 

When you get the TC seated can you feel the drag of the pump when you turn the TC?

[johnceggleston]

i would probably bend and reuse it, but why not use the one off the old trans? still have it?

[CNY_Dave]

I really need to make this an in-and-out job, I just want to be prepared for all contingencies.

 

If I can get the trans ready to slide in before I even take the old one out, that's preferable.

IIRC (please get confirmation from someone else before assuming that I am correct), you can look down the snout of the trans input shaft and see the pump drive-tangs. Casual abuse should not snap/bend these, but EASILY damaged if TC not totally seated and you try to draw engine and tranny together with bellhousing bolts.

 

There is a procedure for seating the TC somewhere on this board, mostly involving how to seat each shaft. Make absolutely sure that the TC is seated, and ensure that it doesn't slide forward out of engagement while horsing the beast around; some people use steel wire to immobilize the TC during installation.

 

(BTW, I didn't follow my advice when I did one, and snapped the pump tangs. I had been feeling frustrated and in a rush. Bad combo...)
