What other symptoms would a damaged thrust washer produce ?

I have normal gear changes almost all of the time ,but every so aften it "hangs onto 2nd " then gives a firm jolt when it engages 3rd.Sometimes does the exact same thing going down the gears.

Will a Tech 2 confirm the solenoid is at fault.

yep that too

If there`s no signs of damaged thrust washer....................sticking 2-3 solenoid

Yep

Looks like I need to have a chat with Tech 2 then before I pull it all to bits and get covered in ATF again.

Symptoms sound exactly the same as mine, also an AR25 - if I remember correctly (MDTM may remember) tech 2 said torque convertor solenoid and low voltage codes.

I dropped the sumps (no thrust washer bits), removed and cleaned the torque convertor solenoid, refilled with clean fluid and checked & cleaned all electrical connections.  All this made no real difference.

My last thought was an alternator issue as I was getting the pulsing/dimming dash lights

Is this solenoid ..2/3 change..accessable from the small sump or the big one ?

That way I might be able to preserve some ATF if I only need to remove the small sump pan.

Looks like a bundle of fun ..upside down peering up at the inside of an automatic gearbox...oh well these things must be done.

Not clear from the images but can this 2/3 solenoid be accessed from just removing the smaller sump ?

I don't think I've ever seen an AR25 thrust washer fail.... plenty of AR35's though

Pressumably ,James,the failure of a thrust washer would not just effect the shifting between 2nd/3rd gears  which would also seem to be related to the loosing drive if that solenoid wasn,t returning or what ever it does ?

In my experience, the thrust washer failure usually means a really nasty jolt from 3rd to 4th...

Cube, it may be that there's a bit of crap in the solenoid or something. Now the ATF is nice and fresh, I'd say drive the car for a little bit and see what happens, pending on MOT result. If still not right in a week or so, worth checking the solenoid...

The T/C solenoid can be got replaced with the small sump removed.
The 1-2/3-4 and 2-3 solenoids can only be accessed after removing the main sump.

Predominantly in 3rd is it?

[amba]

Drive has only been lost on a very few occasions if I remember it was under acceleration so would imagine going up the box from 2nd to 3rd.Engine continued to rev so gas released and fault message appeared.Limp mode came on although drove fine without the benefit of 4th..

The general opinion seems to suggest that the solenoid is at fault causing problems with the 2-3 change more often down shifting..

Just want to be clear on what would be the symptoms if the thrust washer has got damage or has broken up,as I don,t recall seeing any eveidence when I dropped the sump late last year although I didn,t do the last fluid change myself so may have had the evidence "tipped away" on the change before.
