Would it be better to fit an exchange box?
is it true that to repair a gearbox after 97,000 miles , futher problems would be anticipated? have been told it is a bad idea to put new parts next to old - they are not compatible,
any comments ?

less than 100,0000 miles, how long is it reasonable to expect gearbox to last? (after repairs)

Yes it is true. There are many fine tolerances in a gearbox. They wear together and new parts create imbalance. I would go so far as to call it bad engineering practice on a box of that age. A totally different situation one that has certain types of fault at half the mileage.(ex motor technician)

Depends on how well an exchange box has been reconditioned. The company doing it will not have tried it in a car before or after the repair so they probably will only replace the bearings and any obviously damaged parts.
It would be better to cure the problem you have and change the bearings anyway.

Only if it needs repaired. New parts will work OK with old gears unless a gear tooth is chipped or broken off.
There is an old saying about that; "If it ain't broke, don't fix it."
Usually only the roller and needle bearings need changed and the brass synchronizer rings, if any. If it works and does not make any noise, leave it alone. Just change the grease and drive.

It would be best to spring for a rebuild. If you just replace broken parts on an old box, you'll be working on it forever.
There's no problem mixing new parts with good old parts. All new parts have to break in to each other just like new and old parts do, so that's not a reason.

Rebuilt, exchange, same thing, some old bits some new it will work fine if all the damaged parts are replaced, better than new as gears run better when run in.
If the synchronisers have failed is probbly beacuse off lack off or rong tipe of Oil

Depends on value and type of car whether or not its worth putting a new one on.
Never heard of new parts not being compatible.

A properly overhauled transmission will perform as well as a new one no matter what the mileage is.
