2nd gear synchro replacement, What else should be done? Options

[MikeInMunich]

Greetings from Munich!

I’ve purchased a new 2nd gear synchro and am planning on installing it with my mechanic/friend from SOCAL next week while he’s here for a working vacation. We’ve got a lot to do! Installing Mike Blizzard’s ( Hi Mike! (IMG:style_emoticons/default/aktion035.gif) ) 2.0 that he sold me back in March and a lot more.

I cannot downshift into 2nd at high RPMs without grinding unless I rev match.

Otherwise the tranny is good. Even 1st and reverse aren’t bad.

We’re limited on time, but I am looking for some advice on this little job.

Is there something else we should probably or certainly also do while we’ve got the tranny open? I don’t know what the 2nd gear looks like, condition-wise. Should I just replace it as well?

Are there any seals / gaskets we definitely need to replace? I guess the main one for sure, of course, but any others?

Any other advice regarding potential pitfalls would be much appreciated.

How long should this replacement take? (IMG:style_emoticons/default/idea.gif)

Thanks for your support!

The expensive bearings on the intermediate plate. They will usually fall to pieces when you press the shafts out (which you will need to do to replace the synchro).

You may find that the dog-teeth need to be replaced as well as the synchro bands.

Obviously you need the paper shims between the intermediate plate and the transmission case. Measure them and order before you need them...

There's probably more that you should do. I bet Doc E can give you a list.

Thanks Dave!

I just don’t know what you’re talking about. (IMG:style_emoticons/default/sad.gif)

I ordered the „slider“, whatever that is. Not sure what the „intermediate plate“ is either. I ordered the dog teeth as well, by the way. And the paper shims? I need to measure them?? (IMG:style_emoticons/default/idea.gif)

Thanks again for always being generous with your time to be helpful!
