Guest ON3GO Posted July 3, 2003 Share Posted July 3, 2003 is there numbers on the tranny case to tell what year and model it is? if so where do i look? Quote Link to comment Share on other sites More sharing options...
260DET Posted July 4, 2003 Share Posted July 4, 2003 Check out the forum at http://www.classiczcars.com under the What Tranny do I Have? topic. Seems like you should have a Nissan FS5W71B gearbox or perhaps a BW T5 special. The latter has a separate bell housing bolted to the gearbox main case and also a bolted on gearlever assembly, neither of which the Nissan box has.

260DET Posted July 5, 2003 Share Posted July 5, 2003 Far as I know there are no ID numbers on the gearbox itself but the donor car may have the gearbox type on its ID plate. Quote Link to comment Share on other sites More sharing options...

260DET Posted July 7, 2003 Share Posted July 7, 2003 The only other solution I can think of is to check the gear ratios and then see what they match. As you probably know this can be done without pulling the box to bits, by engaging the various gears and comparing the number of output rotations of each compared with one (360 degree)rotation of the input shaft. Then again, if you are really keen and want to inspect the internal condition of the box anyway, remove the front and rear gearbox casings.

Guest ON3GO Posted July 7, 2003 Share Posted July 7, 2003 um im kinda new to all this lol. say what again.... lol. here is a pic of the tranny. thanks Quote Link to comment Share on other sites More sharing options...
Jeff Posted July 7, 2003 Share Posted July 7, 2003 It's easy Mike. Put the transmission in first gear and then place a mark on the output shaft for reference. Spin the input shaft three full revolutions and check if the output shaft is back in its original position. If it is back the you have an 80-83 ZX N/A five speed. The chart that j260z posted simply represents the number of revolutions you will need to spin the input shaft to get one revolution of the output shaft. If you notice all of the five speeds have a number less than one for fifth gear. This is your overdrive and is why your engine sees less RPM at highway speed.

j260z Posted July 7, 2003 Share Posted July 7, 2003 well it isn't the borg warner T5. i can tell you that much. Quote Link to comment Share on other sites More sharing options...
260DET Posted July 8, 2003 Share Posted July 8, 2003 Hmmm. Notice all the external ribs on the two casings, particularly the rear one? They may give a clue. Not like my C series (FS5W71C) box that is for sure. Quote Link to comment Share on other sites More sharing options...
