Ken, I just removed the transaxel from my '83 Euro S about a month ago and the box is currently sitting on my mechanic's bench awaiting parts. The PO of my car had raced it frequently and the syncros in 2nd and 3rd gear were particularly bad. I tried Redline 75W90 which provided some improvement, but not enough. The transaxel is easy enough to remove by following the repair manual sequence. It helps to really get the rear end of the car up in the air. I raised the front of the car about 4 inches with 2x12 planks
and then put jackstands under the rear. The box itself is fairly easy to disassemble down to a certain point. The diff comes out easily (make sure you pay attention to the shims on the axel bearing carriers) and so does all the shift gear. Where things get tough is removing the pinion shaft which requires the use of special tools. I took mine to a factory mechanic who did the rest of the teardown and inspection. He recommended new synchro packages (synchro ring, shift bands, thrust blocks, stops, etc) for all gears, plus new shift sleeves for 1st/reverse and 2nd/3rd. The diff itself and all the gears are in great shape, which is testimony to the robust construction of these units. I am still tracking down parts supplys and will let you know what I find. The estimated labor bill for the shop work (teardown and complete re-assembly) was only about CDN $450. The big cost is in the parts (current estimate CDN $1800). Good luck.
