This morning I took the Auto-box off my dead MV6. I started at 9am, and had it in the boot of the tractor by 10:30. It would have been less, but the OS cat downpipe bolts gave me a little grief - nothing a soaking in plusgas and some help from a little, er, breaker bar couldn't sort!
I then mooched over to Mr Sassanach's place for the post mortem! Dis-assembly showed that while there was no signs of thrust washer in the sump - it had still split, and come adrift. The pump/bellhousing faces were screwed. The clutches all showed some pretty serious signs of slippage - EG burning.
The icing on the cake though was when he took the Sprag clutch assembly apart - it had basically disintegrated internally, and split into many peices.
So these issues will explain the mis-meshing, and loss of drive! The good news is, this was contained within the casing, meaning it could not have got anywhere near the TC.. so that lives on
I am also gobsmacked, because Mr Sassanach has donated me a good AR35!!
(Tango please don't worry, I'll still buy yours for the Tractor, so I can chip it!!)
It was the infamous RonnieMcBurger Box, which was not fitted with the TC aligned correctly. Mr S has popped a nice new bellhousing in there, and the box is fine.
So next step is to finish fitting the new box and fill with nice fresh ATF - tomorrow morning
Sadly, my facilities for autobox swaps are limited - EG ratchet strapping it to a 3 tonne jack and encouraging it up there
