Hello to everyone I finally finished stripping my parts car and decided to look inside the transmission, I am not an expert on gear boxes but this looks really clean, What do you guys think? I'm thinking about just swapping it out with the one in my car with bad syncroes

Other than seeing rounded off dog teeth or chips in gears it is nearly imposible to tell much by looking. Roll the dice or take it apart

5th gear synchro looks pretty good.

Can't see enough of 3rd and 4th synchros to tell much....

Thanks for the reply's I was amazed at the condition when taking the cover off. What your looking at is untouched just the cover removed it looks to me like its new but what do I know about gear boxes other than I cant see any signs of anything coming apart or getting hot.

No combustion gases, nothing to ever make it look dirty. Without thorough knowledge of the condition I would not chance putting one in.

How much hours of labour is a complete gearbox check without repairs? Disassemble and assemble the box?

I spend more time cleaning and inspecting than disassembling and assembling.

10-12 hours. Replacing most of the parts takes no time...old part or new part install the same. The exception are pieces related to the ring and pinion (bearings, damaged gears, installing a limited slip differential.) Set-up of ring and pinion is time comsuming, requires special tools, and special knowledge.

Take a close-up picture of 1st and 2nd gear synchros....that is where the problems occur first.

You've supplied a good picture of 5th gear and a lesser quality picture of 3rd and 4th. These are not very informative....by the time these are worn out, 1st and 2nd are terrible.

Thx Greg,
for the helpful answer.
I think I search an gearbox shop for my 85 S3 box here.
I can play Lego but set up ring and pinion is way beyond my mechanical skills.
