G'day all,
This is my first post so take it easy on me...
OK, I have a 2001 (November) GU series II with an auto transmission.
For a while now occasionally it will noticeably "clunk" down into first gear when coming to a halt, particularly when cold. My wife drives the Patrol more than me in recent years as I drive 1/2 an hour to work and take the little car and she has rang me a couple of time to complain that it is making a strange noise, like a stone stuck in one of the break callipers. But I never seem to get this same noise. I've had a close look at it and can not find anything obvious. I've taken it to my local mechanic and he thinks it may be the auto trany on the way out. It has just a tick over 200K on the clock now, so would it be reasonable for the auto to be about to fail?
Also which auto is in this model? The RE4R03A?
I would hate to exchange the transmission before it is necessary.
How can I tell if the transmission is buggered? It seems to select all gears properly (except for the intermittent clunk into first). It doesn't seem to be slipping excessively. I get it serviced according to the manual.
Can you think of anything else that could cause these symptoms, I have read here on other threads that some auto issues can be caused by the ECU or the MAF sensor and that it is worth purchasing ECUTalk to help diagnose what is going on? Is the ECUTalk system worth buying?
Any advice would be welcome.
Regards
Flip
