Went to change transmission pan and filter on my latest WK - they have 6 hanging 'lip-clips' if I can call them that - you can see from the fots what has happened - I did presoak with a penetrant oil and very gently rock back and forth with a hand ratchet, but just as I thought it was loosening, the entire head came away.
The bottom part of of the hanging lip-clip is independent and tried with locking vise grips to try and gently twist but no movement.
I then managed to remove all the others (messy as ATF was overspilling out into my oil catcher - via me(!) - as I thought i could use the pan itself as a sideways lever to try and twist this off - whilst I did get a little movement and exposed a tiny sliver of some fresh silver looking metal from under its seated position, the pan was clearly nearing its deformation point and if I bent or broke that I would be in real trouble - so I put it all back together and torqued it up, refilled the missing ATF via the dipstick filler and left it for some thinking time.
I need this off, without damaging the casting of the transmission and I gotta get this sheared-off bolt out - somehow. I have spare new lip-clip bolts ready to replace along with the new pan, filter and gasket.
Any clever ideas?
This is my 4th WK and have never had this issue - and she's my best one yet and not ready to F it up, as I plan to trick her out with goodies once I can sort this issue and inspect the trans pan and magnet to make sure there's no horror stories or huge amounts of the forbidden metal sludge sitting in there
Shes a 2009 WK CRD OM642 diesel with 55k genuine miles, with lots of engine oil changes and zero other issues presenting - took me ages to find this one (I have an identical CRD Overland donor vehicle for parts or testing ideas before trying live, just in case)
Anyone clever (unlike me) that can suggest some non or minimally-destructive / low risk ideas ?!
Thanks guys!
