Reached 5 Pic Limit, part two.
I figured it was worth replacing the input shaft seal while I was able to. Be careful removing the old one, I did not have any kind of puller device so had to carefully deform the seal inward with a screwdriver to enable me to remove it. There is a washer behind this seal, be sure to put it back in place before you drive in your new seal.... Especially if your method of removal destroys the seal. Seal is only £7 os so, but it really screwed up my Sunday when realised I had left the washer out having just driven my new seal in.
Amazed me when I saw that all the power and torque form the V8 is transferred to the torque convertor by this thin plate of stainless bolted to the flywheel.
Any ways, all fitted back together OK. It was hard handing over £200 to BMW stealer for fluid but it had to be done. I filled using a long piece of hose and big funnel. Relied on Gravity to push the fluid ino the box. When it started to drop out the bottom I would start the engine and run throught the gears, then get back out a put in more fluid until it began to flow out constantly.
Once I dropped it off the blocks I was unable to properly test the level so I took it to a BMW specialist to Top up.
I've put about 1000 miles on it now with no problems (touch wood). Rebuilt valve body seems to be working well, nice smooth shifts. It can be a bit notchy when cold but I can live with that.
All in it cost me about £450. Fluid was more than the box itself (ebay special).
I wonder what will break next......
Thanks for all your help.
