Which torque converter do I want?

I am getting a new torque converter because my stud that goes into the crankshaft spacer is all geeked up and I keep breaking flexplates, and I think this is the problem. Autozone has two different ones but for the same transmssion, so which one do I want?

There is an ATC Proking, it says special note "lockup" and it is 128.99 I believe.
The second is an ETX for 134.99, but it doesn't say lockup.
The part number for the ATC says AL4d, but the part number for the ETX says FM136HD, will they both work? It has my vehicle specified as an 89 Ford Bronco II 2.9l V-6

The FM136 was a Mitsubishi 5 speed manual transmission so that kinda makes me wonder about that part number......

lol yeah...I wasn't sure what was up with that...so I wonder if that one is really for an al4d and they just put the wrong number in it

I believe I got the one that said lockup...don't all torque converters lockup eventually?...did i get the right one?.

IIRC
Torque converter lock up is kindof a black magic term. They say 'lock up' but nothing is physically rigidly connected. (well, some dodges did, for a few years) when they say lock up it means that both sides are spinning the same. Under heavy load they will 'slip'.

so as long as the converter is for my engine, and transmission i should be fine?

 

[Dishtowel]

I defiantly think so.

if it's spec'ed for your engine/trans, why would it not be fine?

not sure, just the lady at the counter was being real pushy to check to see if it was or not before I ordered it, but I have no clue how to check because it doesn't run currently and is out of the bellhousing...lol
