1. ALL the T-96 transmissions use the SAME rear seal regardless of model. I've had the standard T-96 and T-96 ODs from 61-63 Americans and a 63 Classic. All three used the same rear seal. I ran the Classic OD with an American open driveshaft. You just have a flange on the end of the trans doing nothing. 2. Correct -- ONE BW-10 OD unit for ALL MAKES, not just all AMC models. There were some external differences, such as different wiring schemes, but internally (and the main case) they are all the same. A Studebaker V-8 OD unit will gladly give up it's guts for a T-96 OD unit, or vice-versa. The adapters are different on the 01/10/80 because they hold the seal and they each have different size driveshaft yokes. The 01/10 six has the same size yoke, but then you're looking at open drive vs. torque tube. I'm not sure if the 10/80 V-8s use the same size yoke (diameter, same seal) or not, but as you mentioned there may be a difference between the standard and CV universal joint yokes. 3. The little tube was used to for the rear seal on the American OD unit so AMC wouldn't have to have a special seal made. It's even listed as a "seal adapter", I think. 4. The output shafts for the OD equipped trans is definitely shorter. There is a gear in the OD unit that the shaft splines into. Not sure if that hole/splines are larger for different models or not, but I would suspect the OD units all use the same gear (not different). ------------- Date: Fri, 09 Nov 2007 10:45:45 -0800 From: Tom Jennings <tomj@xxxxxxx> Northwest Parts finally found my trans, and has all the parts, but can't ID the rear seal. I'm looking for an manufacturers part number, if anyone has that data, or knows DEFINITELY whether this is the same hardtop vs. convertible, let me know... There is only ONE BW 10 OD unit for all cars. There are very small differences at the output end to accomodate different models. Some differences are obvious: adapter and seals. However these need examination: 6.330 CLIP and RING. Not sure of their function; application varies, 01, 10, 80. CLIP is used only on 80, so it's CV joint vs. single U-joint torque tube weirdness and is safely ignorable when sticking this mess onto another trans. The 01 adapter is a dinky little tube that holds the final oil seal. Rather than having it's own page in the catalog, it fits on the illustration. (IL6-8) On the transmission output shaft for OD: no information. There's a unique part number for everything, but that doesn't reveal much. There's a different output shaft for 63-64 classic right hand drive vs. left! -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
