Hi. Recently my a44Of started slipping when cold,and then wouldn't change out of first until it warmed a bit. Then no overdrive lockup. Fluid level was right, kickdown cable fine.
I pulled the pan and the filter was very clean. The fluid was clean too. [ I drain and fill 5 litres every 6 months or so with dex111] The magnets had a small amount of fine graphite looking material on them, but overall very clean compared to my cherokee trans when I inspected it. I have a separate fluid radiator mounted horizontally with a fan that kicks in when the temp reaches 1OOC, so the trans has never overheated.
Assuming it's the original trans, it has done over half a million kms, witch is some sort of miracle in itself.
I put the pan back and topped up with fresh dex111, and added some lucas tranny s***e.
Now it changes fine and doesn't slip any more, but no overdrive still. It also seems sluggish at 1OOkmph. It has noticably less power than it had when the overdrive lock was working.
I did the "party trick" a couple of times, but no change.
To any tranny guru's. What is the most likely reason the a44Of stops locking overdrive? The lock up relay control valve is easy to access if I pull the pan again. If this valve is a common culprit I will pull the pan and inspect it. If not, I suppose driving it the way it is should be ok.
Thanks.
