Transmission rebuilders in SoCal? Options

[Tdskip]

Good morning, hoping to get a recommendation on a transmission go-to person or shop. My project 914/6 she’ll came with a 901 with only a little bit of history. Apparently the box is in overall good condition but the 2nd gear synchro is a bit weak.

I’d like to address that now while everything is apart.

I’m also game to give it a go myself if this is something I can/should do myself.

Thanks in advance for the coaching.

I agree with Dr Evil.
Looks like silicone sealer which builds up the gasket thickness. The gasket under the intermediate plate determines the pinion depth. Using silicone sealer increases the gasket thickness which negates the depth adjustment done without sealer.
You should only use sealer that soaks into the gasket. I use Locktite 574 or similar.

Product used here is Three Bond silicone liquid gasket for engines and gearboxes. Product dries flat and does not affect pinion depth.

Still not necessary, not recommended in the factory manual, and I don't use any.

Dimensionless sealant? Reminds me of the time long ago when I was putting some roll on sound deadener in my car and a guy said it would add 400#...the bucket, mixed, was 40#. Magic (IMG:style_emoticons/default/wink.gif)

I will add this, though, the spec is +/- 0.03mm and the used ring and pinions are not as tight as 40 yrs ago (hey, none of us are). They tolerate a lot of slop in setting, I have seen it/done it in the beginning. However, correct is still correct and sealant is an attempt at improving on something that does not need it. Leaks happen from the rubber seals 99% of the time. If it leaks from the paper, that's a bad sign and a case needing truing.
