This is the engine oil colour on my wife's 2007 Toyota Auris 2.0 litre D4D DIESEL engine 1500 miles after a flush with 1 quart Totally Awesome and 5 quarts of oil, idling for 20 minutes.
Appreciate the response. I am very skeptical at this point that it is anything to do with the valve body itself, especially since when I lock the center diff, it shifts through all 6 gears as smooth as butter. Plus the grinding noise I am hearing now leads me to believe it is something else besides the valve body. I couldn't see the valve body make any kind of grinding noise, please correct me if someone knows different. Now I am thinking more it could be differential or transfer case related. I am not sure about this but this is what I am thinking. If I cant figure out the issue by Tuesday I am taking it in to a local trans shop to at least get a diagnosis as to what is wrong and as long as it doesn't require them to remove/take apart the transmission to diagnose, I will probably preform any repairs needed myself.Ok I have gone back in time and read all the two threads. Your initial issue is the same issue I had when I bought my v6 3.2. When under load the 4 to 5 was harsh and sometimes frightening. I had two related issues. The flector (flex) disk was torn to pieces and my speed sensor gave up a few days later. I fixed both so now I have a gentle but still present and noticible only by me shift from 4 to 5 and only when I have done over a 100 km (hot box). Most of the times I don’t notice it but I know I have to take care of it. I thought about getting a new tcm. I bought 20L of ravenol atf type 4 oil and will be doing a full flush then an oil and filter service. I have a thread for this hard 4 to 5 **** too but I havent updated it in a while.
Now back to your issue. I understand you don’t want to lose more money. You need to make sure the revmax valve body is 100% ok. It’s a rebuilt unit so something might have gone wrong after the 1000 miles you put into it. This is what I would do if I were you.
