After contemplating this mod for a coupla years now, finally did it this morning. It went pretty smooth, no corrosion to deal with but getting the circlip out gave me a bit of a challenge, 5 different sets of circlip pliers and none of them would grab worth a darn, maybe the holes are metric sized...Didnt have an issue putting it back in place tho.
I have the plate style holding the trans lines. Beware the two o-rings on each line, one stayed in the block when I removed it, just watch you dont lose either. 10 and 13mm ratchet wrenches to remove, added a 10mm stubby ratchet wrench when installing due to exhaust pipe.
I did some test runs afterwards with "4 stop and look for leaks", quite happy with the results.
