There are 2 types of converter. Lockup and non-lockup. Jeep and later AMC cases are lockup capable, but might not have the internals in place for lockup. The best way to tell is to check the depth of the hole in the middle of the input shaft (with the torque converter off of course!) If it's just an inch or so, it's non-lockup. Then there is the diameter of the converter neck. 727 is bigger than 904, but the 999 in my '83 Cherokee had the larger neck and the 998 in my Eagle was the smaller one (broke several of those hauling my 5 ton trailer just around the yard) Jim Blair, Lynnwood, WA '87 Comanche, '83 Jeep J10, '84 Jeep J10 From: Greg Taylor <amundaza@xxxxxxxxx> To: AMC-LIST <amc-list@xxxxxxxxxxxx>, FSJ-List <FSJ-List@xxxxxxxxxxxxxxx> Subject: [AMC-list] 727 vs. 999 converters ???? Message-ID: <350045.16879.qm@xxxxxxxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="iso-8859-1" Hey guys, Can the 727 and 999 converters be exchanged or are they tranny specific?? A guy is interested in the 727 360 flexplate and converter for his 999 Jeep project.? Thanks for the feedback.
