Today my AW4 exhibited signs of erratic shifting, not slipping but more like it would kick up or down at the wrong times. It shifted fine for the first 200km that I owned it and now has started acting a little funny.
Here are the symptoms:
From start up, everything seems fine. After driving around 5 miles(and subsequently letting the transmission warm up) it started to show signs of erratic shifting.
I reached my destination(around 15 miles from home) and did some business, letting it sit for around 2 hours. Hopped in, drove home and the same thing..shifted fine with NO abnormal shifts or torque converter lockup for around the first 5 miles, then it started acting up again.
I bought this thing not too long ago, and it appears to have had the fluid/filter changed fairly recently(maybe even at the dealership where I bought it, since they did other tune up things at the same time--plugs, wires, air filter,new oil/filter, new 02 sensor etc--quite likely that they did the tranny at the same time).
The tranny fluid is at the right level(a hair above the full level, actually), checked both hot and cold. Fluid is nice and reddish, no signs of wear--it actually looks brand new. would the minute amount of extra tranny fluid cause these problems?
I'm wondering if there is a possibility of the wrong fluid causing these symptoms? The fact that everything shifts fine until it starts to warm up leads me to believe this may be the case. I have read it is quite common for the dealer to mistake the correct fluids and substitute ATF3 for the dexron2 the manual calls for.
To be more specefic about the "erratic shifting", it'll upshift fine into first, second, third and OD at the correct RPM's but when slowing down it will sometimes kick down from OD to 3rd rather erratically, rev to 3000RPM then get back into OD. It'll do the same thing between 2nd and 3rd occasionally too. I don't redline it at all, and accelerate really slowly to allow it to comfortably reach it's shift points instead of stomping it and forcing it to shift too quickly.
thanks!
