<div dir="auto">The syncro cones in the BJ8 gearbox, the ones that use steel syncro rings, have a special coating on them.

<p class="m_3863921813223833434MsoPlainText">My question for you on my transmission rebuilt is when I
was downshifting from third gear to second the gears were grinding I was always
having to double clutch to get it in the second gear. I have replaced just
about every part in the gearbox including the second gear which I thought was
the problem as the synchro was bottoming out or touching the face of gear it
was well worn. Went yesterday for my first test drive and all of the gears
worked perfectly and shifted very smoothly but when I try to downshift from
third to second it grinds terribly I had to come to a complete stop to be able
to shift it into second gear. It shifts from 1st to 2nd no problem third and
fourth gears work very well as does reverse. Do you have any suggestions? I couldn’t
find anything on the tolerances between the gears would you have access to some
kind of chart or spec sheet? My other thought was the plunger in the sliding
hub might not be engaging on the first motion shaft. Any thoughts or ideas for
me to try! <u></u><u></u></p>
<p class="m_3863921813223833434MsoPlainText">I would certainly appreciate any help you might be able
to provide!<u></u><u></u></p>
