'85 G.Wagoneer 727 torque converter, lock-up, high stall, or low stall?

[Luke Harris]

I have a remanufactured torque converter bought for a 1985 Grand Wagoneer with AMC 360 and Chyrsler 727. Does anyone have knowledge on how to tell if this torque converter is a lock-up, high-stall, or low-stall. According to the repair manual there should be a decal on the front of the converter which tells you if it is a lock-up, high-stall, or low-stall. Unfortunately, there is no decal on my converter. There are two stampings in the body of my converter. One reads "B438" and the other reads "8600".

Stock is a non-lock up low stall converter. The lock up converters can be told on the transmission if there is a gap of about 3/4" from where the splines end and the shaft end for the input of the torque converter. vs. a non-lock up the splines will run all the way to the end.

I hope this helps,
Phil

Are you sure about that? I just rebuilt a 727 originally taken from Narnian's 1980 Cherokee, and it required a lock-up converter.

I haven't installed it into my 1984 J10 yet, but I assume they're the same since the 360 engines from both vehicles have a toothed flexplate; a non-lock-up torque converter would have a ring gear, whereas the lock-up type doesn't.

My 727 from my '85 was a non-lock up. I had Advanced Transmission in Iowa City, IA rebuild it and install my TCI upgrade kit. I asked them this question (as I wanted to get an upgraded Torque Converter while I was at it). I asked them what I had and how to tell. That is what they told me. Now, I did not rebuild my tranny myself, but I did handle the remanufactured torque converter and it did have 'low stall' stamped on it and I did examine the shaft to verify what the splines did. I wish I would have taken pictures because (like a few people, I think) I searched for days trying to find an answer to this question. I dunno, maybe I got it backwards, but I don't think so. Easiest way to make sure would be to call a tranny shop . . . Lord knows, I am NOT an expert and have been known to be wrong (just ask my wife :D ).

I hope that helps,
