changing the solenoids is easy.

[Admin]

We speculated (after many hours of serious investigation, mostly by Marks DTM) that the only thing remaining was the internal solenoids. That as we are not an autobox speacialists  , was the point at which we said change the box.

Oh and the thrust bearing in more than one piece at the bottom of the sump was a bit of a sign of a broken box!  

[sassanach]

that thrust washer you refer to is between the oil pump and 4th gear overdrive. what happens is that the gearbox overheats,melts the thrust washer which then lets the overdrive section of the internals float about, which then chews up the oil pump which then makes the whole thing worse.finally the gearbox slips BADLY!!.as a side note there are only 5 solenoids in the entire box all easily accessible when you remove the sumps

Hmmm, wonder if thats worth a try James, removing solenoids from busted ar25 and putting in ar35. That bit would be a zero cost fix? Persumably they just bolt in?  Not sure how hard the thrust washer will be though  :-/

If you have the time, could be a very satisfying fix, though I suspect time is against you.

Failing that, must be an old 3.0l elite on fleabay thats pasts its best, to strip, even make money on?

Jaime - I would have done your idea of soleniod swap (easy peasy to do)  - but it's not worth it, because of the broken thrust washer in my AR35. That's why I changed the box and not soleniods in the first place.

Steve - I too am was agreement with Jaime! As said before, AR25 wasn't intended to last, it was just the only cost effective way of isolating/proving an electrical issue. I knew all along I need an AR35.

Moving forwards, Seems I've located a good AR35 from an MV6, in Nottingham. My good friend Dave has offered to pick it up, and bring it down to me at a convenient time - now that really is a mate.

Just striking a deal, need to confirm it's DEF gearbox, and an AR35 should be en-route!

Does Park work? If so, the prop/diff/driveshafts all OK.

Presumably, we'd know if engine/crank had failed!

So, TC or box. Now, bearing in mind we knew the box couldn't take it anyway, and you were booting it.....

Whatever, you need an AR35 on there, so you need to get one anyway.

[sassanach]

would you care to part with your old ar35?

Sorry Mate, it's already got MR DTM's name on it, when I can get to Notts...

Aye... as per start of this thread, Park works fine, so don't suspect Prop or Dif. Engine runs, so can't be crank!!

AR35 being sourced...

Any odd noises from the box?

None at all

I have just been seriously messed about by a Winker on ebay about the box, I'm spitting fire  [smiley=angry.gif]

[Admin]

Working on trying to find another one now....

You are a very good friend, Dave  

[sassanach]

when your original box failed which came first, the thrust washer failure or the solenoid problem?

We don't know...
