The TH350 is the easiest trans I have rebuilt. I've done 5 of them so far and they are all still going. I attached a link for transmissionpartsusa.com which is were I buy most of my parts. they have the best prices around. I'm not sure if they will ship to the UK but it's worth a shot. There is a book out called "Turbo-Hydro Matic 350 handbook" which is VERY good. I highly recomend it as it provides step by step instructions with lots of pictures. It also has performance and trouble shooting chapters. I agree with the others about a clean area and special tools. I made my spring compressor from threaded rod & angle iron 12 years ago and it's worked every time. Give it a shot.  If you have questions or run into trouble give a shout.

hahaha well thats what happens if u live in england. Actually i also own a jetta and man can i tell u the parts are expensive. if i could have only kept that money used in german parts and used it for american parts for my bird.....it be running mid 12s by now hahaha

A Jetta??? omg lol
Do you need parts? is it cheaper to buy them here?
As for living in England....... it wasnt my fault where i was born.... but we do have fish n chips and proper pubs! etc etc and MINI's eh Rick!

As for the help guys, i cant tell you how much i appreciate it, im hoping to move workshops soon ( to get more space ) so if work doesnt get too busy the Bird will get a makeover!

Jeff thanks for the link, ive added it to my faves. ( ps wheres your bloody passport? )

I rebuilt my TH350 last summer, I was a little intimidated at first, but once I got into it it was actually pretty simple.  I completly disassemble it and took the torque converter and a few parts to a local shop.  I had them flush the converter and run the case through their machine to clean it.  Then I had them install any bearings that needed replacing.  I assembled the rest.  I bought my kit from Northern auto along with a shift kit.  I cannot stress enough that a good manual and torque wrench are needed  during the process.  I took a bunch of pictures, but don't know where I have them.
