I'm having some problems... I hope someone can help...
Here are some bullet points (very hard to summarise these symptoms I'm afraid)...
Recently we towed our caravan to the Convoy for Heroes and on the way there and back I noticed that once we'd been up a few long gradual slopes at 45-50mph with foot-to-floor, for the rest of the journey the TC would not lockup at all. It would attempt it (as above) and the revs would drop, but they would not drop enough and the revs would still go up and down as if it were only part-locked.
So... Ashcroft suggest the "govenor valve" (or something like that) is jammed, and are suggseting I either buy a new TC or a new gearbox with TC. I don't have the cash for this.
My local garage (knowledgable, but not LR specific) suggests I just put some flushing fluid in it for a week and then drain the ATF, replace the filter and fill it back up with ATF again.
What do you suggest?? And if I do drain the ATF and replace it, how many times should I drain/replace/drive for 2 miles/drain/replace/drive for 2 miles etc... to get rid of the old ATF in the TC?
Thanks in advance!!
Here are some bullet points (very hard to summarise these symptoms I'm afraid)...
- It's possible that the ATF and auto gearbox filter has never been changed. It has a regular service history up to 96,000 miles (but with no details), and it's unknown what happened between there and 168,000 miles (where I am now).
- I bought it at 145,000 miles and *I* have not changed the ATF or filter ever.
- Since I bought it (Sep 2010), the torque converter has been reluctant to lockup at 50mph at the start of a journey. Once it's all up to temperature though it locks up better.
- It will lockup better at the start of a journey if I accelerate through 50mph as fast as possible, while ensuring it stays in 4th (i.e. no kick-down). If I gently take it over 50mph or let is accelerate itself down a hill it does not lockup properly at the start of the journey.
- When it "fails" to lockup (as mentioned above), it always does try... it just kinda "half" locks up (i.e. the revs drop at the right moment, but they don't drop enough and the revs still change if I accelerate or decelerate).

It would attempt it (as above) and the revs would drop, but they would not drop enough and the revs would still go up and down as if it were only part-locked.
- When we got there (after 1.5 hours at below 50mph with a few hills) I pulled the ATF dipstick. What looked like a little puff of steam came out the dipstick tube. Probably oil steam. Maybe this is normal?
- The ATF is not the scary "brown" colour, but it does have a hint of brown in it now (after this long journey with the caravan). It's basically still mostly the usual "cherry red", but with a hint of brown in it now...
- My 0-60 time seems to have dropped even though the engine revs are remaining high. I don't care about this, but it suggests something's amiss.
- This morning, I noticed it was reluctant to change from 1st to 2nd... it revved higher than normal in 1st before kicking into 2nd. The rest of the journey was relatively normal.
