This is my g/f's old car that I am just fixing so I am not 100% sure of it's past... Car is a 2001 LS 3.8 with 139,000 miles on it.
I have fixed a few things on the car and it is running great for the most part now... Only issue I have now is that it doesn't appear to be shifting into overdrive. It shifts 1st, 2nd, 3rd just fine... but never goes into OD. It's hard to even tell, and the only reason I did notice is that I was driving it on the highway at 70 mph and the RPM's were at 2800-2900. I moved the shifter from D down to 3, and no obvious downshift or no change in rpm.
Any advise? There was a full tranny system flush done on it at 122,000 miles, which sorta scares me. But that is one of the things I don't know... if the problem started after the flush or what. I was just thinking of trying to add some "cleaner" to the trans fluid, but not totally sure. I will probably just take it to a shop to have it looked at, just wanted to see if there was anything I could look at prior to doing that.
Thank you!
